Doesn't allow third party email clients.

I can recommend Posteo.

I just migrated away from Tuta after trying the service for a year. I like it well enough, but it presented too many frustrations to be a service to pay for.

1. While they have labels (yay!) their inbox rules cannot apply labels so you are stuck manually tagging everything (boo!) - and the UI for manually tagging could use improvement.
2. Mobile (Android) notifications stop working frequently.
3. While they integrate their contacts in to the Android contact list, they refuse to integrate their calendar with the Android system calendar - meaning I cannot pull a consolidated list of calendar events in to my launcher, and am stuck using their calendar application (which could use a lot of improvement).
4. If you set a calendar event reminder, and then change the time of the event, the reminder will go off at the original event time (or 15/30 minutes before, whatever you set it to).
5. Long refreshes when loading the inbox. Navigating back to the application often has the server disconnected, then you have to wait a spell for it to reconnect so you can carry on.

After searching around and checking purelymail, infomaniak, mailbox.org, mxroute, migadu, zoho, etc. I landed on fastmail (with my own domain) predominantly because of their implementation of labels (super slick). Their mobile app and desktop applications are also very slick. Contacts/calendar sync in to the Android System is done through DavX, but I also have it syncing to my Nextcloud instance. It's a more expensive solution than the others, but labels (tags/categories) are such an important part of my workflow that there aren't a lot of options unless I wanted to go back to M365/Google Workspace.

If I was to give up labels, I'd probably go with infomaniak or mailbox.org. Both of their offerings were slick and the price was right.

Killed my account bc they didn't feel I used it enough. F'em..

I just swapped from proton to mailbox.org and I considered tuta heavily.

I chose mailbox over tuta because:

• tuta didn't allow third party clients like thunderbird. Given I jumped to proton from Gmail and now mailbox from proton, I wanted to decouple as many systems as possible if I had to jump again.
• mailbox, if I'm remembering correctly, had better encryption properties except for their calendar. Tuta has an encrypted calendar, and now I'm looking into a self-hosted calendar system.

I think I would still recommend tuta to like my mother or something because it's very clean and easy to set up and good enough. I'd recommend mailbox.org as a slightly harder alternative if you care about your calendar being encrypted.

My opinion on tuta: Can I use thunderbird? No? Goodbye.

There are many alternatives, but given that I haven't switched from a trash free one as I don't want to spend money for just having a mail server, it would be hypocritical to recommend any.

They have a reputation for deleting free accounts. If you plan to use Tuta for more than a few months be sure to use their paid plans, not free.

I have used it a couple years now and I don’t have anything to complain. It has worked perfectly fine all the time.

It's great. It stores and sends email. What could be better?

Posteo is the gold standard for me. They are absolutely solid in terms of values while making no big fuss about their (excellent) work - other than Tuta and Proton.

Payed for 5 years, but now I'm in the progress of migrating to a "regular" mailservice. Problems I have with tuta: The client has become super slow in recent months, it seems to get worse and worse. Notifications don't arrive or arrive too late (Android). No other way than to use it with their clients. No offline support (or at least it doesn't work for me). UI/UX isn't that great either.

Works fine. Android app doesn't require Google push notifications, unlike Proton. I like that they aren't chasing the AI pipe dream.

I'm not a fan of how they use their blog to shit on other privacy projects.

A few weeks ago, they recommended CalyxOS. I informed them that Calyx is a dead project. The next week Calyx is getting recommended again. The person(s) writing their blog doesn't seem to have a clue even when giving the information on a platter.

I like it

paid for a year a while back when they had some discount. will not renew.

like others have said:

• no standard protocols support to use other clients and their clients are shit
• no client improvement in the last year
• their pricing buckets are weird and the price per gigabyte is too high

it's a niche product. if e2ee is the primary goal, that's fine. it's not what most people want/need. as far as I see it, we lack a good service with no tracking/mining and tuta is just too much limiting.

I paid for it for years but it's just too limited. Inbox rules suck. Tags technically exist but are half baked.

Searching your tuta inbox is terrible. By default it sets the search window to a few days, and searching your entire inbox takes (not exaggerating) ~1000x as long as any other provider I've used. Where I expect a few seconds it takes tens of minutes to search a time window of ~1 month which for me might be ~1000 emails total.

Ive lost two accounts due to being inactive on them so I kinda gave up trying

I prefer it over gmail and outlook, but as others have said, it leaves a bit to be desired

Tuta is great, I like it has its own client, in particular Linux has so few options. Thunderbird is became concerning for me based upon FF underpinning & associated AI moves

That said, I team it with Posteo which is also great, and hard to beat the price

Both bring solid reputation & strong company values & ethics 

Tuta works only with its clients

Posteo doesn't do custom domains 

In any case you can try Tuta for free.  :)

I don’t like it because you can’t use the mail address in any mail app. Only in their app or in the browser.

So when they dropped app support for my phone I had to use the web version. But then they also dropped the support for that.

Just like Microsoft they are declaring a perfectly fine phone (MS with PCs) obsolete and make it unusable (MS W11). All in the name of "Security". (Even though you can access the web version of tuta on a PC running Windows XP, a >20 year old OS. I have tried that in a VM after I couldn’t access it on my phone. How hypocritical.)

I am not going to start my PC just to check my emails. I have deleted my account.
