you@gmail.com and y.o.u@gmail.com are same

Sometimes you may receive a message intended for someone whose address resembles yours but has a different number or placement of dots. For example, your address might be homerjsimpson@gmail.com, but the message was sent to a Homer.J.Simpson@gmail.com. What's going on?

Gmail allows only one registration for any given username. Once you sign up for a particular username, any dot or capitalization variations are made permanently unavailable for new registration. If you created yourusername@gmail.com, no one can ever register your.username@gmail.com, or Your.user.name@gmail.com. Furthermore, because Gmail doesn't recognize dots as characters within usernames, adding or removing dots from a Gmail address won't change the actual destination address. Messages sent to yourusername@gmail.com, your.username@gmail.com, and y.o.u.r.u.s.e.r.n.a.m.e@gmail.com are all delivered to your inbox, and only yours.

If you're homerjsimpson@gmail.com, no one owns Homer.J.Simpson@gmail.com, except for you. Sending mail to Homer.J.Simpson@gmail.com is the same as sending mail to homerjsimpson@gmail.com, or even HOMERJSIMPSON@GMAIL.COM. If you're getting mail addressed to Homer.J.Simpson@gmail.com, most likely someone was trying to send a message to Homer.J.Sampson@gmail.com, or Homer.J.Simpson1@gmail.com, and made a mistake. You might even get messages from mailing lists or website registrations because the intended recipient accidentally provided the wrong email address. In these cases, we suggest contacting the original sender or website when possible to alert them to the mistake.

For security reasons, when you log in to Gmail, you must enter any dots that were originally defined as part of your username.

Note: Google Apps recognizes dots. If you'd like to receive mail with a dot in your username, please ask your domain administrator to add the desired username as a nickname.
