Posteo.de or Mailbox.org - Struggling to find an alternative to Proton

Hello everyone! I have been currently debating switching email providers. I have been with Proton for a few years now (free user), but I have become increasingly disappointed. Firstly, I am not exactly a fan of the “we have apps for everything” model, particularly the integration of a password manager is just strange and the crypto wallet feels a bit nauseating, as I have my reservations about cryptocurrency. Consolidating all of my services in a company such as Proton feels misguided if the goal is to avoid walled gardens from the tech giants. There are also some other more recent things that have come up in relation to Proton that just make me question the legitimacy of Proton's “guiding moral imperative” as a privacy focussed company.

Moving on from that, I have mostly settled on two options due to their

  • low cost
  • generally adequate security (I understand email's limitations on this front, I just want something to be secure enough)
  • transparency reports
  • location of operation

The main thing I am struggling with here are the pros and cons between the two platforms.

Posteo seems to be less ideal of an email provider because they do not support ARC and lack a good DMARC policy. BUT they claim to support encryption with their calendars, but does this even matter if you are accessing the calendars with CalDAV (which I do not beliece is an E2EE connection)?

I think I trust Mailbox.org more when it comes to security, but I think their contacts / calendar situation is somewhat worse, and their French translation seems … lacking in spots (not that it matters to me much, but still is somewhat jarring for me).

I could just ignore the contacts/calendar problem, and use something like EteSync, but that would become just another thing to pay for, and another app to operate (if I need to use the WebDav bridge).

Any feedback on this would be greatly appreciated, I am really hoping this inspires some interesting conversations! And of course, feel free to tell me about better options if I have overlooked something. Have a lovely day :)

    Commenting to recommend Fastmail. An incredibly mature and feature-rich platform that doesn't seem to be run by assholes. You own your data and are fully in control of your experience.

    I have been using them for probably close to a decade now since I switched away from Google apps.

    Edit: FWIW I am using around ~10 custom domains with Fastmail and I use both their IMAP/*DAV severs as well as their web suite.

          Mailbox has a plan starting at €1 per month and if you want to use custom domains you are looking at €3. Fastmail starts at €5 per month (if you go for annual, otherwise it is €6)

          So yeah, Mailbox.org is cheaper. Though fastmail does offer more storage in their plans, but that might not be relevant for everyone.

      What seems particularly of interest to me is their support of the JMAP protocol, a seemingly good new option (at least in terms of how fast email protocols change). Notably better support for push notifications on mobile clients, and an alternative to existing solutions for contacts / and soon to be calendar sync. Given the state of clients right now, I doubt I would use it as of now, but it is nice to see them working towards better open protocols for the future.

      Thank you very much for the suggestion :)

          The lack of zero-knowledge encryption is a little disappointing and definitely renders them a worse option, the lack of E2EE however is not a big deal to me as I can just use PGP in my email clients and not have to depend on a server implementation. At the end of the day however, email is quite flawed, and I don't use it really as a primary or essential means of E2EE communication. I would much rather use an app built from the ground up for encrypted communication (e.g. Signal among others) or an app built from the ground up for encrypted file sharing (to replace email attachments)

        FastMail is based in Australia which means they are required by law to comply with Australian police requests (they list annual results of police requests on their website) but interestingly, they’re also required by law to not comply with international requests.

        If you’re worried about the Australian government raising requests then they won’t do much to protect you, but if you’re worried about any other government, then ironically they’re a much stronger defender than many US tech giants which have a reputation of handing details over to all sorts of organisations without so much as a warrant.

        Also, while they currently don’t use your data for harvesting and profiting on the side, they’re also bound by Australia’s Privacy Principles and therefore will have a much more difficult time in future switching to that kind of model if they decide to in future. Still not encrypted, but these other points are what swayed me in their favour recently.

      I have always wondered if it is worth getting a custom domain, but I just don't know what I would use as a name on my more "professional" things (resumes, banking, etc.) . I don't have a small business, so I can't just use the business name, and ideally I would want something that works in English and French, which further complicates things.

      Given your experiences with them, do you have any thoughts on what I could use instead of just cycling_mammoth(at)business-name.com?

        but I just don't know what I could use as a name on my more "professional" things

        I have something not exactly like, but similar to:

        • firstname@lastname.tld for the “normal” address to give out to friends & family
        • fl@lastname.tld (or e.g. f.lastname@whatevercustom.tld) for job applications and bank accounts/insurances/other important stuff
        • Optionally, you could use even stricter “topical” separation. Ever since I made the switch to emails using my own domain in, uhh, 2022?! apparently, I have had a few more addresses for other purposes, e.g. newsletter@lastname.tld for the obvious or accounts@ for any non-critical logins (think Spotify, Anki, Obsidian, etc.), you could even do socials@ for Big (& small) Tech logins, one for orders/purchase receipts on- and offline, and so on.

        Back when I set this up, I got a deal for 25 mailboxes (and addresses) for basically the same price as like… 2? or 5 or something, so I took it for being able to offer addresses to my family alone, the pre-sorting by address is just a rather nice bonus. :P

        Of course, if you don’t plan on sharing the domain with other users, you can always do info@firstlast.<any tld of your preference>, since the likelihood of that still being available is usually higher.
        Also still, you could set up a generic catch-all to hand out to potential spammers/untrustworthy sources à la hello@firstlast.tld (although spam within the EU has gotten better compared to 10-20 years ago due to regulation, I’ve been told). Or you set up firstname@firstlast.tld. Or firstname@pseudonym.tld. The possibilities are endless. :D

        The real reason to get a custom domain is that you don't have to change your email address when switching providers. I wrote more about this and the names I use here in this post.

        For catchall, you'll get a lot of spam because people will just spam (anything)@example.com, so I recommend setting up a subdomain, like biz.example.com. Then use a different name@ for each account, amazon@biz.example.com, hilton@biz.example.com, etc.

        I run the catchall rule into a separate real mailbox (ads@example.com) that I never send email from. That mailbox has all spam filtering turned off. If I start getting spam from one of the name@biz, I just block that one address.

        The provider I use probably doesn't meet your needs, but it's mxroute.com. The operator is based in Texas but I believe the servers are all Hetzner in the EU. Email only, no frills, you are expected to know how to configure your mail. Support is very good for reasonable requests, but he is ruthless about locking down any spam-related activity to protect server IPs. I never have a problem with email delivery, which is my number one requirement as the big providers (gmail, outlook, etc) get more and more strict about their spam/reputation rules.

      Tuta at this point is a tertiary option for me if I decide against these two, but still desire to move away from Proton. My main qualms with Tuta would be

      • lack of PGP support
      • lack of IMAP support (even just for data export, although they do support data export on the site itself on a by-folder basis, so not the biggest of issues)

      However, I do appreciate that it would allow me to keep encrypted calendar / contacts which I have with Proton. It would definitely be more of a "drop-in replacement" in those regards.

      I will have to get back to you on Zoho, as I have not heard of it (and I need to get back to some work right now), but I really appreciate you suggesting a service I have not come across before.

I also have another domain through mxroute which I have because I got a good deal for it.

      Im trying to decide between Migadu and PurelyMail, my main concern with PurelyMail is that it has a bus factor of 1.

      I'm also a happy customer of Purelymail (switch from Migadu too). To @Toric's point there is a bus factor but if and when the time comes that Purelymail shuts down, it's easy enough to switch providers. Worst case scenario is self-hosting.

    Another one to consider: https://privateemail.com/ via Namecheap. It's what I use. Not sure if it meets all your requirements.

      Namecheap went hard into promoting cryptocurrency and Web3 in years past. Any of that come up while using their email service? I didn't even know that was something they offered. I use Porkbun and I guess they offer it too now that I'm checking. I think I just subliminally ignored it as another upsell attempt

        Oh I did not know that at all. I just registered my domains and setup email. Never saw anything about crypto or anything. Honestly that would have made me stop doing business with them.

    I'm personally using Mailbox and I've been overall pretty happy with it. It's easy to add new aliases with my custom domain and I had no trouble configuring K-9 Mail as a mobile client for my email.
