Multiple email addresses for one Gmail Account at Sean Deasy
This is a cool feature I did not know about. You can set up virtual sub-accounts for your gmail just by adding +(whatever). For example, firstname.lastname@example.org wants to add an email newsletter, or sign up on a site say Melinda’s Fabulous Newsletter. John just adds email@example.com and voilà, the email is sent to his regular gmail and is easy to tag.
