As an administrator, you can use address maps to redirect incoming messages to email addresses that are different from the original recipient or destination. An address map is a relationship (or map) between the original recipient of a message and different or additional recipients.
Note: Message forwarding and message redirecting are different. Forwarding changes the content of the original message, and forwarded messages include message history. Redirecting doesn't affect message content, and redirected messages appear to come directly from the original sender.
You might use address maps in these instances:
- An employee left your organization, but you want to get any future messages sent to their employee email. Map the employee email address to the address where you want to get those messages.
- You want to use one email address for multiple recipients. For example, you can map the email address email@example.com to the email address of each of your sales employees. When you send a message to firstname.lastname@example.org, a copy is sent to every mapped address.
- Someone in your organization changed their name and email address. Map their old email address to their new one so they can continue to get messages sent to their old address.
- A person in your organization has an email address that's often misspelled. Create an alias with the misspelled address, then map the alias to the person's correct email address. Messages sent to the misspelled address are redirected to the correct address.
Mapped addresses are stored in an address map table in your Google Admin console:
- Each row in the table represents an address map.
- Each address map can include 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.
