    Comments about Proton Mail as an Alternative to Gmail
    Comment summary: ProtonMail is praised for its open-source nature, strong privacy features, and encryption, setting it apart from Gmail. Users appreciate its ad-free experience and security focus, with many endorsing it as a free and reliable alternative. Although some note its slower feature development and limited free storage, many consider the Swiss-based service to provide substantial user data protection, leading to strong recommendations for those concerned about privacy.

    Protonmail is free, open-source, encrypted (more private). Lacks: calendar & good contacts feature, but these are in the pipeline. Protonmail cannot by design data-mine your software for it's own profit; Gmail makes it's money by violating your privacy that way.

    Proton Mail is my primary email and I have been moving away from GMail. In fact I do pay for it.

    Proton Mail has been reliable and their support has been great. The UI is different and pleasant, and they have apps that cater for different platforms (Windows, macOS, Android, etc).

    Protonmail is pretty great for all reasons listed. BUT it has two major drawbacks that you need to be aware of :

    • Account may be deleted due to inactivity (1 year - free plan) -SMTP (for apps like K9 mails or Thunderbird) requires additional setup, and is not available on mobile devices These were deal breakers for my use cases

    Comments about Tuta Mail as an Alternative to Gmail
    Comment summary: Tutanota is generally praised for its privacy-focused approach, offering end-to-end encryption and not selling user data, which contrasts with Gmail's monetization model. Users appreciate the easy-to-use interface, minimal design, and affordable premium plans. However, there are some concerns about occasional account deletion and the lack of POP/IMAP support, which limits compatibility with some email clients like Thunderbird.

    Tutanota is a great email provider with very good encryption (it uses end-to-end encryption like Signal – i.e. they cannot read your emails/gife them to the government, Gmail can!) and they don't sell any data. It is also very easy to use, it has a very nice app, a desktop client and a web client. There is really no reason why you wouldn't want to use it :)

    AVOID. Deleted my account for not using it, but I had it tied to important accounts. The only way to get the email address back is to buy a paid account.

    Fastmail is an Australian email company that is a complete Gmail killer: 1) You pay with money, not your privacy (they don't data-mine or sell your data); 2) Full replacement for email, calendar, contact - including mobile app. 3) 2 factor authentication (Yubikey & others), infinite catch-all email addresses, file storage. Brilliant Gmail replacement.

    FastMail is the most professional mail service out there, the only problem with FastMail over Gmail is that they do not have good html template support yet, besides that, Gmail does not stand a chance.

    The most secure and private email on the market. As such, there is not free version. This is a good thing, it means they are not making money with your information.

    Lack of labels - only folders. Poor and broken search function on web client (seems to scramble email details in results?) Unable to send through external addresses. Does not group multiple separate emails from same sender. No multiple star colours

    At the moment, Mailbox.org is probably the best Gmail alternative: 1) You pay for the service with money, not your privacy (no data mining), 2) Excellent integration of encryption, 3) excellent Calendar and Contacts (not on mobile yet), 4) Yubikey 2FA, 5) Data stored in Germany (better privacy laws).

    Best Gmail replacement at the moment. You get all the suite functions like the calendar, address book, cloud space, apps for a fair cheap price and the priceless privacy policy and encryption without losing IMAP capabilities as with some even more privacy focused email providers like Protonmail and Tutanota.

    Privacy-oriented and based in Belgium, which ensures your data isn't being sold to anyone. No ads. Overall better performance on the web client. Free plan already offers a plethora of useful features, although you can get more if you pick one of the (cheap) paid plans.
