Include an easy unsubscription link in email marketing newsletters

No newsletter publisher or email marketer likes unsubscriptions. There are at least two good reasons why you should make it easy and fail-safe to unsubscribe, though subscribers who are not interested and never open your message (and who would unsubscribe if they could) are worth nothing and the resources for sending them mail are wasted. Subscribers who want to unsubscribe but fail to do so will turn to you in the end, which means high, unnecessary administrative costs if you have to take them off the list manually. That's why you should make it as easy as possible for your readers to unsubscribe. Still offer a way to unsubscribe via email.
