Why is My Email Blocked While Trying to Sign Up?

The issue is related to the Gmail address used that includes dot within the prefix user.example@gmail.com as we do not allow signups with that format.

"This email is blocked. Please contact site support to find out why."

Google’s Gmail service does indeed ignore periods in the address before the  @gmail.com. A Google support page states that “dots don’t matter in Gmail addresses,” and in the above example, you could even get a message sent to us.er.exam.ple@gmail.com as you own all dotted versions of your address.

Therefore, please remove the dot(s) from your Gmail address when signing up for your Unlocator account.
