If you add dots (.) between the letters of your Gmail username,
sending an message to the new username will get forwarded to your
original email (which is without or with only 1 dot.) For example:

It doesn’t matter how many dots you’ll add between your username, all
of the emails sent will go to your original email. Gmail provides
another great explanation:
Gmail doesn’t recognize dots as characters within usernames, you can
add or remove the dots from a Gmail address without changing the actual
destination address; they’ll all go to your inbox, and only yours. In
short:
- homerjsimpson@gmail.com = hom.er.j.sim.ps.on@gmail.com
- homerjsimpson@gmail.com = HOMERJSIMPSON@gmail.com
- homerjsimpson@gmail.com = Homer.J.Simpson@gmail.com
All these addresses belong to the same person. You can see this if
you try to sign in with your username, but adding or removing a dot from
it. You’ll still go to your account.
Why is this helpful? Let’s say you want to sign up
for a particular newsletter but you’re afraid of spam. Then you can
modify your email with the dots so in case you start getting unwanted
messages, you can use Gmail filters and send every message your ‘new’
email receives to spam directly.
