Unwanted mailing-list emails arriving in your inbox every morning are annoying, but because most of us are eager to get started on our days, we often quickly archive/delete them rather than taking the extra step of unsubscribing. Here's a simple solution.
Rather than dealing with and unsubscribing from mailing-list emails when they arrive — which rarely will come when you feel like handling them — deal with them all at once at your convenience with a quick search. From Lifehacker publisher Nick Denton:
Just do a search for "unsubscribe" in Gmail. Either filter, label, and archive the results or go through and individually unsubscribe. Pretty obvious. But it only just came to me.
Now that Gmail offers to automatically unsubscribe you from mailing lists you mark as spam, you could in theory quickly knock down a lot of list email by trusting their spam-and-unsubscribe method, but in our testing it doesn't do a great job identifying every list email, so you'll probably be better off going into the email and manually finding the unsubscribe link. Still, if you've got five minutes today, you could quickly get rid of most — if not all — of your unwanted mailing list emails with this quick search and a little clicking.
