Inboxes
[email protected] and [email protected] are two inboxes, each with its own mail and its own rules. Categories cut across inboxes.
Create an inbox
Hand out an address. The inbox appears with its first email. On a screened domain, new addresses wait in Screening.
To add an inbox before mail arrives, choose Add inbox under Settings → Inboxes. It gets the default ruleset, and mail to it skips Screening.
Inboxes across domains
The inbox is the part before the @. If you own example.com and yourdomain.com, mail to [email protected] and [email protected] lands in the same dentist inbox. dentist+promo is its own inbox.
Find an inbox
Open Settings → Inboxes.
Rules for one inbox
Open them from the gear on its row in Inboxes, or from the gear on an email's inbox badge. If you set a default ruleset, it's attached when the inbox appears. Rules covers when a rule belongs in a ruleset.
Stop mail to an inbox
To stop mail to one, add a Bounce rule to it. See Bounce.
Send from an inbox
Compose from any inbox, or type a new local part. See Sending email.
