Google Group Email always displays a footer


Issue

When I send a message via Google Groups, the email received always displays this footer:

You received this message because you are subscribed to the Google Groups "xxxxxx" group.
To unsubscribe from this group and stop receiving emails from it, send an email to xxxxxx+unsubscribe@googlegroups.com. 

Environment

Google Groups 

Resolution

You cannot remove the default Google Group footer from emails sent from the group.

This is to comply to with the CAN-SPAM Act.

In email sent to external group members, the footer always contains information on how to unsubscribe from the group. This footer can't be changed or removed.
