Apps that need to send emails or receive emails.

Love the lifetime deal. 10GB across any number of accounts. That’s what I’ve got.

I only use it for automations (both send and receive); I’m on Proton for regular mail. They’ve got a few different web interfaces, so I think you can get spouse approval. Not sure on local storage (outside of POP/IMAP).

I can highly recommend MXroute. Just works. Great for integrations.

Use DNS validation

I… don’t actually know. I wouldn’t think that would be necessary (at least manually).

It transfers across other peers; you don’t have to have a direct connection to the recipient, just an eventual connection to them.

I’m currently eating pie for breakfast, so this confused me at first.
