I also receive emails and invites for someone else but I actively use my Gmail account. I think it's just people misspelling email addresses.

I've got several of these for one active email in particular. I've always thought it was bad data entry. There is a cluster in the US south - Georgia, Texas and Alabama.

At first I tried to rectify the mistakes but gave up due to lack of response.
