I’m not the person you were asking, but I recently tried tried Tuta with my own domain and decided to look elsewhere due to a few things;

• No way to import mail, despite it being announced as “worked on” back in 2022. This is a fairly huge blocker IMO.
• Email rules don’t seem to apply until you view (and I assume decrypt) your mailbox. This led to some annoying behaviour like push notifications for emails that should have had rules applied to them.
• Spam filtering is all over the place - it’s overzealous and filters legitimate emails, and at the same time it lets in plenty of actual spam.
• The mobile apps are odd - you get realtime push notifications, but when you open the app and view your mailbox, it takes 20-30 seconds for it to show the email it just notified you about (even if you tap the notification).
• Their history of outages and instability are a big cause for concern IMO. Email is a crucial service, so uptime, deliverability, and data integrity are paramount.

For routine/non-sensitive email, they feel like too much hassle for the average punter in my opinion. And if I put on my industry hat; their frequent downtime is a huge red flag, and a sign that they either don’t know what they’re doing or don’t have enough cash to operate properly.

Having said that, I still think they’re the best current option if privacy/encryption is your only concern - to the best of my knowledge no one else takes that quite as seriously as they do.

I’ve been using Tuta since 2018 so I’ll give you some of my gripes:

• The domain gets blocked by spam filters when I email other people. Not necessarily Tuta’s fault but annoying.
• I get a ton of spam and phishing emails. A ton. Everyday I’m flagging like 4-5 of them.
• Tuta just got labels. I can now label my emails but Proton had it for years (I also use Proton)
• Tuta constantly have outages. I hope they improve their infrastructure.
• I personally like Proton’s UI/UX better
• I use the desktop client in both Windows and Linux. The Linux one is an Appimage that I have to run using --no-sandbox and I just don’t feel comfortable doing that. Proton has Proton Bridge which I can use to interface with Thunderbird which I prefer. Now whether it’s as secure or not I don’t know because security isn’t my specialty but I like using Thunderbird for my email client.

Edit 1: fixed typo

 I'm so sorry but the Harvard Guid
 to Margin Spacing Standard is very off. 
 Sorry.

BW is great Chefs Kiss $40 a year for 6 people, it’s a good product made by people who seem to care.

I’m using PIA, it’s not great, but i’m not doing great things nor and I doing them quickly. They’ll give you openssl certs and you can do programmatic crap AND have a dedicated port.

Tuta is pricey for what you get. 8/month/user for email/cal with reasonable storage, No office apps, i need to replace a LOT of google services. Still have a lot tied up in their auth/store. And honestly encrypted email (AAS) is mostly worthless. It’s not encrypted between them and office 365 or google and everyone is already reading those in transit. And Google/MS are already mining/selling the content. If you’re not talking tuta<->tuta you might as well be broadcasting it.

The $3 for the shared box seems like a slap in the face. You’re literally already paying them for service/storage.

You can host thousands of email users on a couple of modest boxes for a couple hundred a month.

Main downside of Mullvad is no port forwarding anymore

Personally going with option 2 on an old PC, learning a lot about docker lol

Have to be careful in planning, a lot of ISP’s block common ports needed to host dns/web/email

Getting DKIM and SPIF running locally has a bit of a learning curve.

The real pain is SMTP. Even if you set up everything perfectly, a lot of mail providers won’t accept SMTP traffic from a home IP.

I think my longterm plan is to just keep a free gmail and try like hell to never use it.
