The e-mail address the message was sent to. Because many people have more than one e-mail account, it is wise to include the e-mail address the message was sent to in the footer, as in, "This e-mail was sent to firstname.lastname@example.org." This makes troubleshooting opt-out problems much easier.
- Why they are receiving they message. If you haven’t done it elsewhere in the mailing, you should include a statement about list origin, such as, "This mailing was sent to you because you asked for new product announcements from Company X." This reminds the customer what they signed up for, and from whom.
- Customer service contact information. Provide an e-mail address, call center number or both. Remember to note hours of operation. If the customer has an account rep or sales manager assigned, you might also include the contact information for this individual.
- Copyright statement. Nearly every company Web site has a copyright statement in the footer, but a surprisingly large number of e-mails from those same companies lack copyright labeling. Check with your legal counsel to see whether your footer should include a copyright statement.
- Trademark. The most conservative companies also like to identify their proprietary marks in every document, as in, "Silverpop and the ‘dot pattern’ are registered trademarks of Silverpop Systems Inc." Check with your legal department to see if this is a practice you want to adopt.
One thing you never want to put in your footer is a statement about how well you comply with CAN-SPAM. Not only does it sound a bit self-serving but, ironically, it may actually increase your chances of getting filtered as spam.
Incorporating helpful information into your e-mail footer is good practice, a wise use of space and, moreover, your customers will appreciate it.
