I tend to sign up for email lists, and most of the time it works okay, since people and companies are getting smarter about not selling their lists. But after a while I start to notice more and more unsolicited emails. Then I go on a purge, unsubscribing from every list that is starting to annoy me. The political ones are especially bad. Fortunately the unsubscribe process has become much easier than it used to be. At the bottom of every email is an Unsubscribe link, sometimes in very tiny font, admittedly. It only takes a minute to go through the process, though some lists make you enter the email address you’re unsubscribing and some don’t.
Afterwards I feel as if I’d lost 10 mental pounds.
Update: in IOS 10, the Mail app shows an Unsubscribe button. Click on it and IOS does the rest.
