Currently thinking about either Tuta or Mailbox.org, but to be honest, I don’t even know many providers.
Something I do not like is limit on number of addresses with a custom domain. Mailbox is at least a bit reasonable with 50 on Standard, but Proton’s 10 on Mail Plus is disqualifying for me.
Tuta has unlimited number, but doesn’t support PGP.
So I plan to check out whatever you guys use.
I’m using hover.com because I’ve been too lazy to change since my old provider got folded into them years ago.
They’re expensive and lately it seems bank-security emails are silently not coming in (Docusign signature requests and Huntington Bank password reset emails… )
I don’t know if the silent failures are because of my private domain or because of the backend provider. I wish I knew how to figure that out.
