Do periods matter in Gmail addresses? I get messages addressed to my account at firstnamelastname@gmail.com but also to firstname.lastname@gmail.com, and none of these seem to be meant for other people. A. Google’s Gmail service does indeed ignore periods in the address before the @gmail.com. In fact, a Google support page states that “dots don’t matter in Gmail addresses,” and in your example, you could even get a message sent to f.i.r.s.t.n.a.m.e.l.a.s.t.n.a.m.e@gmail.com. Because Google owns the googlemail.com domain and uses it in some countries, you can also get messages addressed to firstnamelastname@googlemail.com.
