Redirect incoming messages to another email address

As an administrator, you can add an alias to an email address to map incoming messages from one address to another. For example, you might have an employee leave your organization, but you still need to make sure that you don’t miss any messages from your customers.

These maps function like a virtual user table. You don’t need to create individual routing settings for each address mapping—just add an alias to the email address that you want to redirect.

Limits on mappings

  • Each address map can have up to 5,000 recipient addresses. Depending on your email sending practices, we may reduce the recipient address limit for your domain. This can affect recipient limits for your address maps. We recommend you follow our best practices for sending mail to Gmail users.
  • Address maps can be created at the top-level organizational unit only.
  • You can create an unlimited number of address maps.
  • You can map an individual recipient address to a maximum of 12 addresses.
