List-Unsubscribe Header Makes Unsubscribing Easier and More Trustworthy

By Justin Premick

Some people don’t trust unsubscribe links, even from legitimate email senders. Others don’t want to be bothered locating the unsubscribe link in your email. In both cases, recipients may click the “spam” button in order to unsubscribe, raising your spam complaint rates and possibly reducing deliverability. Wouldn’t it be nice if ISPs made unsubscribing easier and more trustworthy for users (at the same time reducing your complaint rate)? One major ISP is already doing so.
