Comparing a few based on cheapest annual plan that includes custom email domains:

mailbox.org € 30.00 / $34.71

10GB+5GB storage, ample aliases, multiple domains, up to 10 family accounts

proton.me € 41.04 / $47.88

15GB storage, 1 account, 10 encrypted email addresses, 1 domain

fastmail.com € 51.44 / $60.00

60 GB storage, 1 account, multiple domains

For more accounts/users (e.g. Proton Unlimited or Fastmail Family), the pricing is reasonable. But mailbox.org certainly looks like the best value at first glance unless you need a lot of storage. If you've got 6 users and/or several domains, FastMail does look pretty nice.

purelymail.com: $10.00*

unlimited** storage, unlimited accounts, unlimited domains

*or possibly less if you choose pay-per-use pricing

**soft limit if you use way too much

I love PurelyMail, it's cheap and it works well. But it has some downsides:

* it's based in the US

* it's run by a single guy (bus factor = 1)

Not anymore, now it's actually a team of 3 :)

Wow, didn't know that, that's good!

You need to add VAT to the Fastmail price, I just renewed 1 year for exactly 60€.
