I’ve been aware of this little hack for quite a bit now but I thought it was worth the post for those not in the gmail pimp club.
Gmail has an interesting quirk where you can add a plus sign (+) after your Gmail address, and it’ll still get to your inbox. It’s called plus-addressing, and it essentially gives you an unlimited number of e-mail addresses to play with. Here’s how it works: say your address is email@example.com, and you want to automatically label all work e-mails. Add a plus sign and a phrase to make it firstname.lastname@example.org and set up a filter to label it work (to access your filters go to Settings->Filters and create a filter for messages addressed to email@example.com. Then add the label work).
See you aren’t really generating new accounts just gmail addresses that are a smidge different than the one you got that go to your same old account. So don’t get too excited.
But it could be usefull to many people who like automation, which I happen to love.
