One trick you may or may not have picked up about Gmail is that you can add in periods anywhere in the front part of your address and it makes no difference whatsoever: email@example.com works just the same as firstname.lastname@example.org. What’s more, you can add a plus sign and any word before the @ sign (e.g. email@example.com) and messages will still reach you. If these tweaks make no difference, then why use them? One major reason: filters.
