If you have a primary inbox with different aliases set up, you can have each alias forward to a Reamaze for proper email management. Gmail has the ability to have each alias forward on its own.
Simply go into your Google settings > See all settings > Filters and Blocked Addresses > Create a filter, then make sure your alias is added to the "to" field. Then, click on the next tab over - Forwarding and POP/IMAP. From this tab,make sure that you select "disable forwarding."
If you has multiple aliases associated with one email address, you will want to create an email channel for each alias in Re:amaze, otherwise emails from each alias will import into the same channel. To create a new email channel, simply head to Settings > Email Channels > +Add a Channel.
This will allow you to set it up so each alias forwards to a different Reamaze channel. In Reamaze, you'd create a channel for acme-mail1@acmecompany.reamaze.com and acme-mail2@acmecompany.com. No workflows needed.
