If you have a primary inbox with different aliases set up, you can have each alias forward to a Reamaze channel for proper email management.
Simply go into your Google settings > Forward and POP/IMAP > under Forwarding "Create a filter" > Filter on "To".
Gmail has the ability to have each alias forward on its own.
This will essentially allow you to set it up so each alias forwards to a different Reamaze channel. In Reamaze, you'd create a channel for email@example.com and firstname.lastname@example.org. No workflows needed.
