You can customise the footer that appears at the bottom of every email sent to your group. This can be useful if you want to provide a footer in a different language or just provide extra information about your group.
All footers on emails sent over Gaggle Mail must contain a link for the recipient to change their membership settings or unsubscribe. You can insert this link into your custom footer by adding the label |MemberLink|. A default footer will be added if you don’t want to provide a custom one.
See here for a full list of customisations.
