I think most of you know the Gmail . trick meaning you can use your gmail address and then split it with a . and it goes to the main account.

myemail@gmail.com and
my.email@gmail.com both go to myemail account. This is good as it allows you to get special offers as a new user when available.

myemail+pinterest@gmail.com sends any email to
myemail@gmail.com so if you start getting spam from myemail+pinterest.com you know they have sold your data
