I prefer creating a unique email alias from dots more than plus. Especially if I sign up for something I'm worried will leak my email address to a third party, I use the dots. A malicious sharer of emails could trivially strip all the "+site@gmail.com" before sharing, but they can't know ahead of time if they get my primary email by adding or removing dots.

Also, a few times when I've signed up with "name+service@gmail.com", I've then failed to unsubscribe because their unsubscribe form didn't accept the + but the subscription form did.




The malicious sharer could modify the rule to not only remove the "+site" part but remove all the dots. Then, your trick is useless.

They might realize the "+site" and not the dots, but your point was about ability not awareness. ;)


except my "real" address has dots, so I know that 0 dots are being cleaned. I just can't tell who did it.


Which doesn't provide extra information for you, as you probably don't go around subscribing to spam mailing lists.

But all right, '+site' is more well known, so it does definitely work better.
