Stop Telling people that you have dot in your email address. Don’t emphasis on that. It does not matter if you are using Gmail.
In general if the email address is firstname.lastname@example.org then if you send mail to email@example.com then it fails in most of email providers.

In Gmail firstname.lastname@example.org = email@example.com firstname.lastname@example.org= email@example.com Google decided to do things differently from other email providers when it launched Gmail.Namely, it decided to ignore periods in its users’ email addresses altogether.That’s right—they make absolutely no difference. Following are general restrictions on using period from different email providers based on few experiments.
