Signature - Add Multiple Signatures - Airmail for macOS

Go to Preferences > Account settings (double tap the account listed) > Signature tab to change or add
signatures to your outgoing email messages. Signatures are created on a per-account basis, so you can
configure each email account with multiple signatures.

Additionally, you can control whether a signature is automatically added to a message (again, on a per-
account basis). Just go to Preferences > Accounts > (select an account) then click on 'Composer' tab.
Choose whether to add a signature to the message while replying.

You will notice in the above picture that you can also include signatures in Quick Replies.
