Lifehacker: “One Gmail, one address. That seems right. After all, you have one phone number, and one home address. The same should be true for your email addresses, Gmail included. As it happens, though, your Gmail account has an unlimited number of addresses you can use whenever you want, fooling everyone from Netflix to spammers alike. There are actually a couple of methods here. The first is what allows you to turn your single gmail address into infinite addresses, through a tactic called “plus addressing” (a fitting name). In order to take advantage of plus addressing, you simply type a plus (+) after the local-part (the name before the @), then type whatever you want. For example, if my Gmail address were [email protected], I could type [email protected], or [email protected]. The service you’re using that email with will think it’s an entirely new address, but any emails to that address will still be sent to your inbox. This works for any Gmail address, even if the domain isn’t gmail.com.”
