The ease (or lack thereof) of unsubscribing from email newsletters has become a recurring theme here for almost ten years. It came to a head last year, when the phenomena of abusing customer email lists became the norm.
So for future reference, I’ll be grading sites based on the following criteria:
[ ] Newsletter was opt-in in the first place [ ] Unsubscribe link exists in newsletter [ ] No need to confirm unsubscribe [ ] No need to login to unsubscribe [ ] No need to find “email preferences” [ ] Reasonable time to unsubscribe (< 48 hours)
A site needs all six to get 100%. One unticked box deducts 50%, then 10% for each subsequent box. As far as I’m concerned, slipping on two or more of these represents a failure.
