Promotional emails
For launches or offers, use campaign names that describe the promotion. This makes comparisons easier when several emails point to the same page.
Signature links
A link in an email signature can also be tagged. This is useful when you want to separate everyday one-to-one email traffic from newsletters or promotions.
