Gmail Users Got a Free 2nd Email Domain

In case you don't know, a Gmail account actually get you two email addresses. The first one is the regular username@gmail.com while the second email address is username@googlemail.com. So this is a 1-For-1 package!

So what's the use of having 2 domains but sharing the same mailbox? You can give your @googlemail.com address to your personal contacts while using the @gmail.com address for public use. Having said that, you can create a filter specifying all emails to your @googlemail.com address as not spam.

More than a year ago, I made a post on how to use the plus + sign trick to find out who is the one giving away your gmail account for spamming purposes. Read below link for further details.
