Basically, put a period anywhere in your name and switch the domain between Gmail and Googlemail and you have countless options for email customization. And that’s not all, you can place as many dots as you want, it can be even something like ‘J.o.h.n.D.email@example.com’ and you’ll still get it on ‘JohnDoe@gmail.com.’
That's a good alternative to using different email addresses for various purposes (work, school, friends, etc.) Just filter all incoming mail so that mail sent to "Name.Surname@gmail.com" can be put into a work folder and messages sent to "NameSurname@gmail.com" can be put to "friends," etc.
As for tracing spam, Gmail lets you embed random text to your email address using the ‘+’ sign. So to make sure that your subscription with that news site you wanted access to isn't flooding your inbox with spam, register with "JohnDoefirstname.lastname@example.org."
