Footers and Headers are like email signatures. They can contain your unsubscribe link, your postal address, and any other related information. Footers are very important because they can affect whether or not your message is CAN-SPAM compliant.
The All Headers and Footers page is where you can view all of the headers and footers you have created in your account. By default, there are two existing footers in your account, the CAN-SPAM Complaint Footer and the Default Footer. You can click on the name of a specific header or footer on the All Headers and Footers page to view information about that header or footer. You can also click on the HTML and Text tabs to view the HTML and Text versions of a Header or Footer.
While it is perfectly ok to just use the 2 default footers, you may consider building multiple headers and footers if you have more than one email marketing program. For example, the footer for your monthly newsletter might be different than the footer for your weekly update.
Note - You can not add headers to template messages.
Note - You need both versions (Text and HTML) of a footer so we can include the footer for both text and HTML versions of you message. The plain text footer accompanies plain text versions of your message and the HTML version accompanies HTML versions of your message. Additionally, in order to comply with the CAN-SPAM Act, we automatically include an opt-out link in all footers.
Tip - For more information on special tags, see Using Special Tags in help.
Tip - You can use content tags to create re-usable blocks of content that can be used in the header, footer, or body of your message.
