Thanks!
Mailbox.org is a commonly recommended service beside Tuta and Proton. I was going to switch from Proton to Tuta to have more custom domain emails but it doesn’t allow service outside of its apps. Mailbox.org is cheaper and allows 50 custom domains :)
I searched and searched about this and every response of theirs I found gave the same speech about IMAP not being as safe as their apps.
