1st: You can append a plus “+” sign after your name

So adding any text after “+” sign still get the emails to your inbox, but you can filter based on this additional email id. E.g.:

your.email@gmail.com and your.email+subscription1@gmail.com and your.email+bank1@gmail.com

will both deliver the emails to your.email@gmail.com !

2nd: Gmail DOES NOT recognize the dots “.” in the email ID.

So your.email@gmail.com is the same as youremail@gmail.com or y.o.u.r.e.m.a.i.l@gmail.com
