Gmail Alias API
Developer email infrastructure

One inbox. Every alias. Complete control.

Gmail Alias API lets applications create unique plus-addresses and retrieve messages routed to each alias through a secure, authenticated API.

How it works

Create an address such as [email protected]. Gmail delivers the email to the underlying mailbox, while this service identifies the alias and makes the message available only to its owner.

Built for responsible access

Every user authenticates with a bearer token. Alias and message queries are scoped to the authenticated user, and Gmail access uses a read-only OAuth scope.
