Dots don't matter in Gmail addresses
If someone accidentally adds dots to your address when emailing you, you'll still get that email. For example, if your email is email@example.com, you own all dotted versions of your address:
Note: If you use Gmail through work, school, or other organization (like yourdomain.com or yourschool.edu), dots do change your address. To change the dots in your username, contact your admin.
No one else gets your emails
No one can take your username
Your Gmail address is unique. If anyone tries to create a Gmail account with a dotted version of your username, they'll get an error saying the username is already taken.
For example, if your address is firstname.lastname@example.org, no one can sign up for email@example.com.
No one sees your mail
Your account is still private and secure. Emails sent to any dotted version of your address will only go to you.
For example, firstname.lastname@example.org and email@example.com are the same address and go to one inbox.
What to do if you get someone else's mail
Adding dots doesn't change your address, so dots aren't why you got someone else's mail. Instead, the sender probably mistyped or forgot the correct address.
For example, if someone meant to email firstname.lastname@example.org but typed email@example.com, the message went to you because you own firstname.lastname@example.org.
Notify the sender
If the email seems irrelevant but not suspicious, reply to the sender saying they have the wrong address.
