Secondary addresses in Google channels work (almost) just like they do in email channels, so this article is lifted (almost) verbatim from here.

Secondary Addresses

Secondary addresses (also known as aliases) allow you to send emails with a different “From:” address from the one on the account.

Once you add a secondary address, you can configure a group to start sending emails with it.


👀 Secondary addresses must be added and verified in your Gmail settings first.

Gmail has its own process for adding and verifying aliases (under Settings > Accounts and Import > Send mail as). If you add an alias here before adding it in your Gmail settings, Google will refuse to dispatch it.

G Suite users may need to contact their administrators in order to add aliases in their Gmail settings.

Your email provider may also be set up to receive incoming messages for many addresses in the same mailbox. If this is the case, be sure to add your alternate inbox addresses here.
