@Tutanota very tempting. Just when I promise myself to save money.
One suggestion is a solution or integration to simplelogin. That tool is very handy and it has some kinks to work out with Tuta.
@Chiquidrakula @Tutanota
Just started using #tutanote and use it with #simplelogin !!
In mailboxes you add your tuta email.
Then for every alias, you select the new mailbox.
Have fun !
