If you have several email addresses, e.g. Gmail for work and Protonmail for personal stuffs, you can add them into SimpleLogin and create aliases for them.
A (real) email address is called *mailbox* in SimpleLogin.
When creating an alias, you can choose which mailbox that *owns* this alias, meaning:
- emails sent to this alias are *forwarded* to the owning mailbox.
- the owning mailbox can *send* or reply emails from this alias.
You can also change the owning mailbox for an existing alias.
The mailbox doesn't have to be your personal email: you can also create aliases for your friend by adding his/her email as a mailbox.
