I'm looking to finally get my spouse and I both onto a non-G email service with a custom domain. Having storage and calendars to replace Drive is the deal-maker with the spouse.

I've been using Proton as my alt email for years, but all the new crypto bells and whistles just seems sus from a business management perspective. I get it, they're Swiss, but still.

But looking at Mailbox.org, their 2FA situation seems bonkers. That's the dealbreaker for me.

All I really need is IMAP, webmail, and actual security without feeling like I'm going to be doing this all again in 5 years to get out from under another crypto bro.
