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 aliases differently. I let every mail through that is send to my domain. Then at websites I register with an alias per website and only create an alias in my Fastmail once the alias is starting to send spam so the mails will be removed whenever an email is send to that alias.
What if the web site sends an email that you need to read and it goes to the alias and gets deleted
Yeah that can happen. Usually its just some webshop that got hacked and leaked my email alias. Than it is easy: block all emails to that alias and create a new account whenever I shop there again.
It has happened twice this year that my email was leaked from a company that I could not just remove my account or block all mails. In those cases I changed my email address on their website to a new alias.
