Gmail – Tag Hack

when signing up for potential spam add +spam to your gmail address.
ex: myemail@gmail.com > myemail+spam@gmail.com

then when you receive the spam you can filter it out by telling gmail
to put everything with a +spam into your spam folder.

you can do this by signing into gmail and clicking on the “Create a filter” link
right next to the search box.

works for other tags
ex: myemail@gmail.com > myemail+newsletter@gmail.com
