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 email@example.com then if you send mail to firstname.lastname@example.org then it fails in most of email providers. But you need not worry in case if your personal or corporate email provider is Gmail. In Gmail email@example.com = firstname.lastname@example.org email@example.com= firstname.lastname@example.org 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.
