Footer

The footer is the bottom section of an email where additional information and functionalities are typically included. It commonly contains essential elements like the unsubscribe link, contact information of the sender, physical address (required by laws like CAN-SPAM), links to manage subscription preferences, social media links, and sometimes legal disclaimers or company information. 

The footer ensures compliance with email regulations, provides recipients with options to manage their subscriptions, and offers a way for recipients to contact the sender or engage further with their content.
