SimpleLogin FAQ

What exactly is an email alias?
An alias forwards mail sent to it to your inbox, and you can also send mail from it, so contacts see the alias as your address.
Why use an alias instead of plus-sign subaddressing?
With plus addressing, replies show your real address as the sender, while replies to forwarded alias mail are sent from the alias.
