  • Excellent Service Great For Privacy! Apr 29, 2021

    By Against Goggle
    I am a ProtonPlus paid user, I started with a free account but I actually paid 2 years in advance I like it so much. I really am not cool with advertisers having the ability to read my emails which often contain much personal info. The ONLY reason I am giving 4 stars instead of 5 (which is not really protons fault) is because there are some companies that will either not accept your email address from proton or some online stores that will cancel your order when you give them as your email. It has only happened a couple times so far. I’m pretty sure the reason they don’t accept is because they are assuming your are some kind of criminal or scammer because you have a private email. When in actuality it’s because people are starting to realize what are huge problem we are facing with these tech companies knowing every detail of our life and mind. Anyways I’m hoping as more people start to use Proton, the stigma will be erased. Also if you notify proton of this they contact the company that is denying your email. Other than that it’s great! Some great features for filtering your emails into different folders too
  • Nice mail app for privacy Jun 17, 2021

    By Joejoejoe344
    I’d love a dark mode. Also, the search feature shouldn’t pop up like it does, but rather it “inbox” should be replaced with a search bubble and you should be able to search while not obstructing your emails. Additionally, it should refresh the email search after every letter and not finally when you click “search”. Furthermore, there should be a badge notification on the three line icon (hamburger icon) when you have an unread email in a folder that you’re not in (i.e. if I’m in inbox and there’s an unread mail in spam, there should be a red “1” to the top right of the hamburger button. Also, the swipe on any individual mail to mark it “unread” should mark it “read” if it is already marked “unread”. It shouldn’t just keep marking it “unread”, I shouldn’t have to open the email to read it. I should be able to customize folders from within the app. Besides these suggestions, the privacy is unrivaled. Update: I appreciate the developer’s response! I do hope to see some of these features in the next update (dark mode is of high priority on my list🙂). I actually figured out how to customize folders. You have to have opened an email and then you can add a new folder. I feel like this should be a side bar option (when you click on the hamburger button it should be in there somewhere). Thanks again for responding, looking forward to what you all do with it next!

  • Can’t send important emails/inconsistent Nov 19, 2020

    By Milzc
    I’ve been using Prtnmail for a while, and it has recently been brought to my attention that I haven’t been able to send emails to specific secure emails, namely to my Credit Union Financial Operations (finops) and to the Claims Adjuster of my insurance company. Additionally, I can’t use my ProtonMail email address as my primary email address for my bank account, as they don’t allow anonymous email addresses to be used by their customers. Is/are there ways to get around my issues I’m experiencing? These are important emails, and I wasn’t aware that they didn’t go through until I had contacted the aforementioned companies to follow-up with my emails. Had I not contacted my Credit Union, I would not have known that my email message didn’t get received by the finops department of my Credit Union. On the other hand, I did receive an email alert immediately after attempting to send my message to the Claims Adjuster stating that my message failed to deliver. Can somebody at ProtonMail lend me assistance or explain the reason(s) as to why my messages aren’t going through? How can I resolve this issue? This is a deal-breaker for me, and I’ll need to find a secure email server that I can use for more consistency/reliability. It makes me wonder whether or not other important email messages I had “sent” were actually sent to the recipient(s).

    When you set a timer and password on an email, and save as draft - the next time you send it, the two options don't apply and it's sent without self destruct mode or password. A reminder "you'll lose assigned pwd or expiry timer when you close the composer" would've been reasonable. Otherwise, nice app.
  • Great email service, buggy iOS app Apr 17, 2021

    By Steve the Geek
    I’ve been on a paid plan for several months and highly recommend ProtonMail, the service, in general. It does what it’s supposed to do, and the privacy focus is first rate. However, this iOS app suffers from two defects— one an actual security risk if unnoticed by a user, and one merely annoying. The serious defect is in the PIN/TouchID feature to lock the app. I use the PIN option (leaving TouchID disabled) and it usually works well enough, but from time to time I’ll open the app and it immediately shows my Inbox without a PIN. I contacted ProtonMail support about this, and was asked if the problem occurred after an app update. I couldn’t determine that, as I have my phone set to auto-update apps. The only workaround is to logout of the app entirely. My other apps with PIN lock features have maintained that setting for years, across major app upgrades. The annoying defect, as others have noted, is the lack of notification synchronization across devices with ProtonMail apps logged into the same account. If I read a new email message on one device, the badge on the other device’s app icon still indicates the unread message. This is by no means a deal breaker, but it should be fixed for a polished experience.
  • Great service, lacking a few features to make it a home run Feb 22, 2019

    By HeySRI
    ProtonMail is an excellent service for both the privacy conscious and the masses. The reason so many email providers are free is because it the provider is in a privileged position to scan all of your emails. ProtonMail sets itself apart from the rest, and doesn’t read your email, or store it in a format that they can access. I would highly recommend a paid plan, even if you don’t need any paid features. Pay for your usage with your money, not your data. However, the absence of one feature makes the ProtonMail experience painful (-1 star): No notification dismissal syncing. If I read an email on my iPad, it will still show the notification on my phone until I open the app. Almost every other mail/chat app has notification dismissal syncing, but when I asked ProtonMail about implementing this feature, they said it was not possible. If they found a way to add this feature (and it’s possible considering other services can do it), then this service would be a true 5 stars.
  • App Keeps Getting Better May 22, 2020

    By Mick Gator Fan
    (The prior #4, below, was "Need ability to search entire email message for key words, not just search the subject and sender." This is now in the app. The new #4 is also a request for a new search feature: search urls in bookmarks and Favorites.) ProtonMail itself is generally very useful. I've been a paid user for at least 2 years, and am very pleased that the email account comes bundled with ProtonVPN. My experiences with Support have all been positive; the Support staff is knowledgeable and helpful. However, the ProtonMail app still needs a few features to make managing email easier; I see that other people have asked for some of the features. This list is numbered by importance to me: 1. Need ability to select multiple messages from a filtered list to be able delete, tag, or move them to another folder. Having to open each message one at a time to do this is tedious. 2. Need ability to filter by date range. 3. Need to have sub-folders. For example, I would have a main folder called "Travel" and then have a subfolder for each destination or year or whatever makes sense. 4. The addition of the Favorites folder is helpful, but it is still tedious to find bookmarks to move into the Favorites folder. App needs the ability to search the bookmark urls, and once the desired bookmark is found, we need an easy way to move it to or from Favorites as well as open it or delete it if it's no longer needed.

    Great email app to use! Dr. Mercola said to use this and that's how I found Proton! So far it is the best email that I used! I switched from Gmail to Proton. No ads here which is awesome! Privacy is great too! 5 stars earned! ⭐
  • Underestimated this App Jul 24, 2021

    By Anthony Richard
    Initially, I downloaded this application for sending contracts and sensitive financial data, but I have completely converted over. I’ve used Spark for years, and Airmail as well, so I was used to over-the-top features and loads of automated mailboxes and various pins, flags, etc. Proton is simplistic and minimalist in aesthetic, and when you first start toying with it, it may seem a bit underwhelming. HOWEVER, once you create some labels and folders, link your business email and all the normal “set-up” that goes along with adopting a new application, its simplicity is its strongest advantage. No more do I feel overwhelmed and under informed by what is in my mailbox. I don’t feel like I need to spend all this time setting up automations and remembering color codes (because Proton uses WORDS+COLORS! Simple thing, yet so helpful). Overall, it’s just streamlined my workflow, taken away the clutter, and simplified my mailbox life. Something I was in desperate need of! Try it, give it a chance, and I promise you won’t regret it.

  • Can No Longer Recommend Apr 8, 2021

    By RJudeWade
    I recommended this app/service—to many of my friends, based on its public stated credo and no longer can—having done so to THE NICEST PERSON I KNOW—she contacted me saying she—terminated her account with “protonmail” and opened another—and was IMMEDIATELY sent a message (mansplaining) internet ABUSE and that “protonmail” may terminate her account (she did this trying to get an address similar to the one she was replacing from another service). This is on the same day that her long standing email was high-jacked and all her contacts and mail deleted and sent scam spam (hundreds of friends and colleagues received emails—myself included). I recommended protonmail trying to give her a positive approach to a catastrophic occurrence. It’s one thing to only allow one free account-it’s another to not allow an individual to change it (which might be done for a myriad of reason). This ironically occurred on the same day that I was going to subscribe and donate (despite the all too apparent lack of diversity on their team—one token women which explains the heavy handed tone in a first email to a new client). If this is how they communicate with new clients I’m glad I didn’t get in any deeper with them. Like most tech companies they are only great when everything is working, but woe to the person who has an issue and expects to be treated both civilly and as an individual.

    I've had enough. Over the last year, I've watched server speeds slow down to a crawl, and new services dry up. Waiting 10 minutes for new emails to load every day is the last straw. Go elsewhere for secure email.

    Emails are basically not loading anymore. Also be aware that if you buy an annual subcription and cancel it early, it will not cancel the next DD, but will stop the benefit immediately without any refund.

  • Still no email threads???? May 22, 2021

    By Aniphone5suser
    ProtonMail is the only email client I’ve used that doesn’t have an option to thread emails of the same subject and/or from the same sender. If you’re having a conversation with someone and want to find a precious message, you have to scroll through ALL of your inbox and manually search for the email. If you receive frequent emails on the same subject, like updates on a specific forum, your inbox will be flooded. Instead of having one email chain, you’ll have dozens of emails of the same subject and from the same sender crowding up your inbox. And it will be difficult to pick out any important emails. It’s ridiculous that the ProtonMail developers haven’t fixed this problem. Even tiny obscure email clients with a single developer have better UI, and they at least respond to complaints. ProtonMail is clearly not interested in addressing the problem. Update May 2021: I originally wrote this review about a year ago, and I received a response that email grouping was in the works and would be implemented in a future update. Well, a year later, ProtonMail still doesn’t have the very basic, essential feature that every other mail service has. The word “feature” doesn’t even sound right. Is grouping text messages by contact really a “feature” on my iPhone? No, it’s expected. There’s not a phone on the market where you have to scroll through all of your text messages to pick out individual replies to read a conversation with someone.

    I paid for year of VPN service thru Proton, promptly forgot my login and never ended up using it. Fast forward a year later, I'm being billed for another year of service and can't log in to cancel from my phone. By the time I hear back from customer service that I must reset my password and manually cancel my sub, I'm told I have a prorated charge from when my VPN sub lapsed til now and won't be able to check my emails til I pay-- holding my emails hostage, despite email being free. I'm so mad.

    Does what's needed, notifications somewhat reliable, doesn't have access to all the account management functions (like creating new email addresses) in app so you still have to use the website even when you have the app. Custodial PGP key holding is a very questionable security practice, too. I know people losing their keys could be an issue so having it as the default makes some sense, but forcing it on people does not. You don't need to store my keys, they're called private keys for a reason.
  • Doesn’t support multiple log ins at a time. Jan 25, 2020

    By Fototico
    I really like Protonmail. It lacks some features that I must have. For example, the app only let’s you log in into one account at a time. Making having more than one account impractical. With other services I have multiple accounts for different reasons. Fir example, one is for business, another for personal, and another for junk sing ups. Doing that with Proton app requires me to log out from on and log in into the other. A true hassle! I also find it a bit expensive compared to other private e-mail services. Proton starts at about 52 dollars right now per year. Compare that to Tutanota which is a great service for only 13 and change dollars per year. Tutanota is based in Germany and they take privacy serious. With end to end encryption and even a free encrypt calendar. One annoying thing is how the app always adds a “sent from Protonmail Mobile.” I always delete that before sending my e-mails. Other apps let’s you remove that automatically even on their free accounts. Just lousy that Proton forces it on their users. None the less I like Prtomail. Enough to be my second choice to go to for private e-mail service. Second choice only due to pricing. Otherwise both services are just as good. Why I gave it two stars? Took one start off for the lack of multiple account support. One star for pricing. And one star for the “Sent from Protonmail Mobile.”

    Great encrypted mail, so far I have enjoyed the experience, there are just a few little tweaks I would love to see: - Structure sub-folders and parent folders accordingly instead of all at the same level (in app) - Add a "Suggest an Improvement" button as well as a "Report a Bug" - I know it's only beta but a Proton Drive app please! I want to have a full proton suite like google but no information stealing 😊
  • Excellent email service, private and secure Jun 16, 2019

    By Chief Bruno
    If you value security and privacy use ProtonMail. Even the free accounts are private and secure. They do not sell your information or scan your emails for keywords to send ads. I have both a free account and a paid account and they both work great. I have been using protonmail for a few years now and I love it. The app features are fine. It has all the necessary features plus security and privacy. Some people are too picky they want an app that covers everything and I don’t think there is an e-mail app that has every feature and still keep you info private and secure. I’ve read some of the reviews, and I have not had any issue with crashes or glitches. Some reviews don’t sound like they are about this app. Not sure what some people are doing.

    Great mail option. Although my regular emails can be intercepted and viewed this email gives me the possibility to encrypt my emails. All I have to do is to give the recipient a password. (Not with SMS and definitely not over the phone). Sad times indeed.
  • Great basic email app Jan 8, 2020

    By Nethik
    I moved my custom domain from GSuite to ProtonMail mostly due to privacy and security concerns. ProtonMail as a service is solid and reliable. I love it so far. The ProtonMail iOS app (as of the time of this review) is a bit sparse in terms of features, but it’s reliable and I haven’t had any issues. ProtonMail is a solid option for those looking to take their data protection seriously. Currently, the app is lacking some basic features that I’ve come to expect from a typical email app. For example, a calendar (which the team is currently working on), dark mode, and the ability to switch between multiple accounts without having to log in and out. I look forward to when the team finally to rolls out some of these quality of life features.

    Email the way it used to be, only secure and private. Nice and sleek. I use the free version and I'm pretty happy with it. I don't get twenty spam mails a day every website I visit. I recommend this to anyone. It's easy to use. I would describe proton mail as peaceful and quiet 😃
  • Excellent Service Great For Privacy! Apr 29, 2021

    I am a ProtonPlus paid user, I started with a free account but I actually paid 2 years in advance I like it so much. I really am not cool with advertisers having the ability to read my emails which often contain much personal info. The ONLY reason I am giving 4 stars instead of 5 (which is not really protons fault) is because there are some companies that will either not accept your email address from proton or some online stores that will cancel your order when you give them as your email. It has only happened a couple times so far. I’m pretty sure the reason they don’t accept is because they are assuming your are some kind of criminal or scammer because you have a private email. When in actuality it’s because people are starting to realize what are huge problem we are facing with these tech companies knowing every detail of our life and mind. Anyways I’m hoping as more people start to use Proton, the stigma will be erased. Also if you notify proton of this they contact the company that is denying your email. Other than that it’s great! Some great features for filtering your emails into different folders too

    When you set a timer and password on an email, and save as draft - the next time you send it, the two options don't apply and it's sent without self destruct mode or password. A reminder "you'll lose assigned pwd or expiry timer when you close the composer" would've been reasonable. Otherwise, nice app.
  • Great service, lacking a few features to make it a home run Feb 22, 2019

    By HeySRI
    ProtonMail is an excellent service for both the privacy conscious and the masses. The reason so many email providers are free is because it the provider is in a privileged position to scan all of your emails. ProtonMail sets itself apart from the rest, and doesn’t read your email, or store it in a format that they can access. I would highly recommend a paid plan, even if you don’t need any paid features. Pay for your usage with your money, not your data. However, the absence of one feature makes the ProtonMail experience painful (-1 star): No notification dismissal syncing. If I read an email on my iPad, it will still show the notification on my phone until I open the app. Almost every other mail/chat app has notification dismissal syncing, but when I asked ProtonMail about implementing this feature, they said it was not possible. If they found a way to add this feature (and it’s possible considering other services can do it), then this service would be a true 5 stars.
  • App Keeps Getting Better May 22, 2020

    By Mick Gator Fan
    (The prior #4, below, was "Need ability to search entire email message for key words, not just search the subject and sender." This is now in the app. The new #4 is also a request for a new search feature: search urls in bookmarks and Favorites.) ProtonMail itself is generally very useful. I've been a paid user for at least 2 years, and am very pleased that the email account comes bundled with ProtonVPN. My experiences with Support have all been positive; the Support staff is knowledgeable and helpful. However, the ProtonMail app still needs a few features to make managing email easier; I see that other people have asked for some of the features. This list is numbered by importance to me: 1. Need ability to select multiple messages from a filtered list to be able delete, tag, or move them to another folder. Having to open each message one at a time to do this is tedious. 2. Need ability to filter by date range. 3. Need to have sub-folders. For example, I would have a main folder called "Travel" and then have a subfolder for each destination or year or whatever makes sense. 4. The addition of the Favorites folder is helpful, but it is still tedious to find bookmarks to move into the Favorites folder. App needs the ability to search the bookmark urls, and once the desired bookmark is found, we need an easy way to move it to or from Favorites as well as open it or delete it if it's no longer needed.

  • Excellent Privacy Focused Email Jul 12, 2020

    By JeffTPharmD
    TLDR version: great app/service for the price. App could use some creature comforts from an app like Spark or Airmail. It does what it advertises and does so at a fair price, especially if paired with their VPN product. In my opinion it works best when paired with something like gmail for the items where security isn’t as critical. That way you’re not missing out on the convenience of google for certain items (family calendars or contact sync to iDevices for example), at least until Proton is able to provide solutions for those use cases. Only suggestions to make this mail app better would be to have a one touch option for archiving a message on the screen when I read a message. Currently one must either call press to open the menu bar further then again the archive, or press the folder button at the top then choose the folder and press apply. The second functionality improvement would be use of share sheet or at least ability to export a message as a pdf. Every now and then it’s nice to be able to forward an email to someone as a text and export to pdf makes that happen easily. The other suggestions are cosmetic only, and that is more color schemes, at least a light and dark would be nice and the option to use other app icons. The lock is nice but they also have the various proton logos that would work well too.
  • Face ID not working to login to App Mar 17, 2019

    By VC Fan
    It seems that Face ID is not working to login to the App. I’ve tried multiple times by first logging in manually and then enabling Face ID. But every time I logout and then try to log back in, Face ID is not initiated. I login manually again and see that Face ID is disabled. I enable it again, but it goes back to being disabled every time I close the App. Is the Face ID function only for access when the App is logged in, or is it designed to allow fore using Face ID to login when initially opening the app? Reply to developer: I saw your reply and do not agree because after three days of trying, the App will now allow me to login with Face ID. I don’t know what changed in the App, but I just kept doing the same thing. I have now installed the ProtonMail App on my wife’s phone and Face ID is working properly too. Increased my rating from 3 to 4 stars. Update #2: thanks for replying back to feedback so quickly! No, I did not need to choose or select any keychain or password icon. When the app is completely closed (swiping up from the bottom, on both an iphone X and XS Max, to close the ProtonMail app), then pressing the PM icon only once to open the app: FaceID now comes up immediately and after correct recognition, the PM app is unlocked and accessible. It was not like this when I first installed the app, but now it works this way.
  • Service is great; app needs creature comforts Feb 20, 2021

    By Swinebone091516
    All in all, I love Protonmail. I appreciate their mission to promote encryption and secure services through email and how they value privacy over all else. I’ve been a user for a professional email account for over 2 years and it’s rare that I’ve had any problems with the iOS app or the web app. When I do have problems, it’s usually relatively easy to report them and get them fixed in an update. One thing that I would appreciate, however, is some more perks and creature comforts associated with the iOS app. For example, the ability to schedule emails would be great. Equally, I’d love it if notifications synced between devices. I understand that Protonmail’s main focus is security and privacy (which I wholeheartedly appreciate) but it’d be great if they could compete a bit more with services like Gmail or Outlook.
  • Almost everything I need Aug 22, 2019

    By Baron von Snek
    I've been a paid subscriber for a while and this app works almost perfectly with the following exceptions: 1. No option for threaded view of messages (something that the web app does support and is sorely missed here) 2. Sometimes the inbox doesn't refresh automatically when a new email notification is triggered. I.e., I'll get a notification of a new mail, tap the notification to check it, open the app, and see no new emails in the inbox. I'll have to manually refresh to see it. 3. After refreshing the inbox to see new mail as in #2, tapping the new message to read it doesn't work for a moment or two. I usually ends up tapping two or three times in my impatience 4. This one is not specific to the app, but the service. It's not clear how much of my data is stored with zero-access encryption. It seems that the contents of emails are, but that senders/recipients and subject lines aren't. When I use the search feature in the web app, my search query is sent to the API and it returns a list of messages with subjects or senders that match my query. If the API can search that data, then it must not be zero-access encrypted. This was a bit surprising to me. I'd like to see these details spelled out more explicitly.
  • Secure but not as efficient as I’d like Mar 17, 2021

    By Jclark345
    I appreciate having secure email that values my privacy. As such I upgraded to the paid version and installed the bridge so I could sync it with outlook on my desktop (this feature is not yet available for mobile but we are told it’s under development). The purpose of this review is to request some simple features that would improve efficiency. I would like the ability to click on a folder marked Unread as a way to filter these emails and find them more quickly. Also I have seen screenshots at review sites that showed an email preview but haven’t been able to configure a preview of email while viewing the list of all emails. It’s a much faster way of skimming through all the emails we get deluged with daily. Was this feature lost inadvertently during a prior update?
  • Can’t send important emails/inconsistent Nov 19, 2020

    By Milzc
    I’ve been using Prtnmail for a while, and it has recently been brought to my attention that I haven’t been able to send emails to specific secure emails, namely to my Credit Union Financial Operations (finops) and to the Claims Adjuster of my insurance company. Additionally, I can’t use my ProtonMail email address as my primary email address for my bank account, as they don’t allow anonymous email addresses to be used by their customers. Is/are there ways to get around my issues I’m experiencing? These are important emails, and I wasn’t aware that they didn’t go through until I had contacted the aforementioned companies to follow-up with my emails. Had I not contacted my Credit Union, I would not have known that my email message didn’t get received by the finops department of my Credit Union. On the other hand, I did receive an email alert immediately after attempting to send my message to the Claims Adjuster stating that my message failed to deliver. Can somebody at ProtonMail lend me assistance or explain the reason(s) as to why my messages aren’t going through? How can I resolve this issue? This is a deal-breaker for me, and I’ll need to find a secure email server that I can use for more consistency/reliability. It makes me wonder whether or not other important email messages I had “sent” were actually sent to the recipient(s).
  • Great email service, buggy iOS app Apr 17, 2021

    By Steve the Geek
    I’ve been on a paid plan for several months and highly recommend ProtonMail, the service, in general. It does what it’s supposed to do, and the privacy focus is first rate. However, this iOS app suffers from two defects— one an actual security risk if unnoticed by a user, and one merely annoying. The serious defect is in the PIN/TouchID feature to lock the app. I use the PIN option (leaving TouchID disabled) and it usually works well enough, but from time to time I’ll open the app and it immediately shows my Inbox without a PIN. I contacted ProtonMail support about this, and was asked if the problem occurred after an app update. I couldn’t determine that, as I have my phone set to auto-update apps. The only workaround is to logout of the app entirely. My other apps with PIN lock features have maintained that setting for years, across major app upgrades. The annoying defect, as others have noted, is the lack of notification synchronization across devices with ProtonMail apps logged into the same account. If I read a new email message on one device, the badge on the other device’s app icon still indicates the unread message. This is by no means a deal breaker, but it should be fixed for a polished experience.
  • Great services, app needs work Jan 27, 2019

    By wlh2
    Very pleased with the email and vpn services. Recently bought a visionary plan to try out a year in hopes of migrating all my domains emails under proton. While the web email works perfect and the iOS apps function ok, I have a big qualm with the UI of the app for iOS. The left column sidebar has this huge separate area, that does not appear to be moveable or collapsible, that lists link to settings, bug reporting, log out, and more. This utility section separates the main mail inbox, trash, archive, etc., from the user designated folders and labels, thus requiring scrolling past the utility section to see folders. It’s an annoyance, folders should be with folders. You can see what I’m talking about in the 3rd preview pic. On the web based, this is not the case, and user creates folders & labels are right under main inbox, trash, etc. this is the way it should be, folders in the mailbox section. I really wish this would be fixed to be either the same layout as web based, or maybe user configurable. Rarely do I need settings or bug reporting, but I use folders and labels multiple times a day for different emails and organizing, and the current app makes this not very cohesive layout. Maybe nit picky, but I am not sure I’d be able to deal with moving all my emails to the service if the app keeps this layout. I’d be bummed as proton supports folders and labels for emails, which I love.

  • Multiple Reinstalls of App Feb 19, 2018

    By Kimalah
    I like using Proton to encrypt my emails, and it works great for me on Mac. However, in the two months I’ve had the app on my iPhone (always keeping iOS updated to the most recent), I have had to delete and reinstall three times. The app stops opening for me. I try to open, it shows it is loading for a couple of seconds, and then crashes. When I reported the issue, I was told to update my iOS, which I had stated in my submission was done before sending the bug report. The alternative offered was to join the Beta. I am not comfortable with participating in Beta testing. Otherwise, there was nothing else to offer. I am not happy with this response as it seems others use the app without this issue and give 5 star ratings. I gave 3 stars because when it works, it’s great. But until this issue I am experiencing is fixed, there will be no improvement in my rating.
  • Can No Longer Recommend Apr 8, 2021

    By RJudeWade
    I recommended this app/service—to many of my friends, based on its public stated credo and no longer can—having done so to THE NICEST PERSON I KNOW—she contacted me saying she—terminated her account with “protonmail” and opened another—and was IMMEDIATELY sent a message (mansplaining) internet ABUSE and that “protonmail” may terminate her account (she did this trying to get an address similar to the one she was replacing from another service). This is on the same day that her long standing email was high-jacked and all her contacts and mail deleted and sent scam spam (hundreds of friends and colleagues received emails—myself included). I recommended protonmail trying to give her a positive approach to a catastrophic occurrence. It’s one thing to only allow one free account-it’s another to not allow an individual to change it (which might be done for a myriad of reason). This ironically occurred on the same day that I was going to subscribe and donate (despite the all too apparent lack of diversity on their team—one token women which explains the heavy handed tone in a first email to a new client). If this is how they communicate with new clients I’m glad I didn’t get in any deeper with them. Like most tech companies they are only great when everything is working, but woe to the person who has an issue and expects to be treated both civilly and as an individual.

    Does what's needed, notifications somewhat reliable, doesn't have access to all the account management functions (like creating new email addresses) in app so you still have to use the website even when you have the app. Custodial PGP key holding is a very questionable security practice, too. I know people losing their keys could be an issue so having it as the default makes some sense, but forcing it on people does not. You don't need to store my keys, they're called private keys for a reason.
  • Doesn’t support multiple log ins at a time. Jan 25, 2020

    By Fototico
    I really like Protonmail. It lacks some features that I must have. For example, the app only let’s you log in into one account at a time. Making having more than one account impractical. With other services I have multiple accounts for different reasons. Fir example, one is for business, another for personal, and another for junk sing ups. Doing that with Proton app requires me to log out from on and log in into the other. A true hassle! I also find it a bit expensive compared to other private e-mail services. Proton starts at about 52 dollars right now per year. Compare that to Tutanota which is a great service for only 13 and change dollars per year. Tutanota is based in Germany and they take privacy serious. With end to end encryption and even a free encrypt calendar. One annoying thing is how the app always adds a “sent from Protonmail Mobile.” I always delete that before sending my e-mails. Other apps let’s you remove that automatically even on their free accounts. Just lousy that Proton forces it on their users. None the less I like Prtomail. Enough to be my second choice to go to for private e-mail service. Second choice only due to pricing. Otherwise both services are just as good. Why I gave it two stars? Took one start off for the lack of multiple account support. One star for pricing. And one star for the “Sent from Protonmail Mobile.”

  • Still no email threads???? May 22, 2021

    By Aniphone5suser
    ProtonMail is the only email client I’ve used that doesn’t have an option to thread emails of the same subject and/or from the same sender. If you’re having a conversation with someone and want to find a precious message, you have to scroll through ALL of your inbox and manually search for the email. If you receive frequent emails on the same subject, like updates on a specific forum, your inbox will be flooded. Instead of having one email chain, you’ll have dozens of emails of the same subject and from the same sender crowding up your inbox. And it will be difficult to pick out any important emails. It’s ridiculous that the ProtonMail developers haven’t fixed this problem. Even tiny obscure email clients with a single developer have better UI, and they at least respond to complaints. ProtonMail is clearly not interested in addressing the problem. Update May 2021: I originally wrote this review about a year ago, and I received a response that email grouping was in the works and would be implemented in a future update. Well, a year later, ProtonMail still doesn’t have the very basic, essential feature that every other mail service has. The word “feature” doesn’t even sound right. Is grouping text messages by contact really a “feature” on my iPhone? No, it’s expected. There’s not a phone on the market where you have to scroll through all of your text messages to pick out individual replies to read a conversation with someone.

    I paid for year of VPN service thru Proton, promptly forgot my login and never ended up using it. Fast forward a year later, I'm being billed for another year of service and can't log in to cancel from my phone. By the time I hear back from customer service that I must reset my password and manually cancel my sub, I'm told I have a prorated charge from when my VPN sub lapsed til now and won't be able to check my emails til I pay-- holding my emails hostage, despite email being free. I'm so mad.

    The service is great, but this app sucks on Android. I get notifications for new messages, but when I enter the app, the inbox hangs on its update, and the new messages don't appear. I have to exit the app, restart it, load the inbox again, and even then, wait another minute for messages to appear.
