May I ask why you did not like Tuta? They now have unlimited email addresses for custom domains, which is pretty neat IMO: https://tuta.com/blog/summer-releases-2023

I've been running my own mail server for 10 years. It fought me for nearly a year before I got it configured correctly, but since then I haven't had to do anything other than updates. Works great, no delivery issues and no spam to speak of.

I'd love to recommend running your own server, but I really don't. It's terrible and you'll hate it.

Also don't run your own server and let your boy/girlfriend to use it as their primary account unless you're cool with administrating your ex's email for the next decade.

I also self hosted my own email server but to be honest, even if you setup the server correctly and even if DNS and anything else is configured properly, some big player will reject your mails and you will have struggle to get your mails out of the spam for bigger companies. That takes even harder in place when you rent a new server with a maybe abused IP address. I switched some years ago for all work related stuff to a hosted exchange from Microsoft and pay around 5$ per month for one tenant. I never had problems with my mails being rejected or forwarded to spam anymore.

For sure you can host your own mail server and you can make it run with the most providers out there but you will always have some mailboxes you will not able to get your mails out of spam when you are a small player with a single mailserver.

Migadu has been good to me at $19/year for a couple domains, a few mailboxes and some decent features like distribution lists. They don't hard enforce limits and I've never come up or been warned about it.

I've been using Proton for a few years with my custom domains; no complaints so far.

Edit: Actually, when writing this I only had the web version in mind. I do have complaints about the Android app. It sometimes does not send an email and if you press the Send button again (because of no feedback/no idea if it's sending or not), it sometimes sends an _incomplete_ email. Which is actually a really big problem - I'm just lucky enough for it to be a rare occurrence because I usually only send email from desktop.

I use Google Apps now because the pricing for Googlers is too good to pass up (practically free, 48 times cheaper than iCloud+), but before that when I was being frugal I just set up gmail with my own domain (no payment required).

If your org is more than one person, this might get unwieldy.

FastMail is absolutely flawless. Their feature improvements are always on point as well.

icloud+ and custom domain works fine for me. icloud+ is $0.99/month and it comes with other features like hide my email (I didn’t know I need it until I discovered it) and extra space in iCloud storage (I don’t use it).

previously I used Proton but I recommend staying away form them at all costs.

1. their android app will send previous drafts and disregard your later edits. 2. That is if the android app even works. as other people reports, sometimes the send button does not respond. it also regularly just spins when trying to open an email. 3. they are discarding their Google reviews for their app. they used to have 20% 1 star reviews, which was reasonable.

in the end it seems they focus hard on marketing without maintaining their product. they have switched on the value extraction faucet.

I use ProtonMail, mostly via the web interface. I do have the Android app installed, but I rarely need to use it for writing emails, so I can't speak about it being broken.

Own mail server. For critical mails i have an posteo address.

I have personally used fastmail and I am happy.

I have personally felt Microsoft/Outlook service is better than Gmail. I have a couple of clients in shipping business, and they had issues with Gmail. Moved them to Outlook in 2018 and they are still happy.

Of recently, I have suggested Zoho to some clients. Its been good.

We use Migadu.

(since 2011) I'm self-hosting Postfix with dovecot through openvpn on Linode. I plan to release ansible playbook with my setup.

I've been enjoying purelymail quite a bit

iCloud+ for me as part of Apple One. Works as expected although the spam filters are not as good as with Gmail.

I've been using 1and1 to host warot.com and whatever else I decide to tinker with, for over a decade

I have been using Proton Mail.
