my wife gets these regularly. there's a few people in the UK (we're in the US) that have similar gmail addresses as hers, and use her email address often. she'll get restaurant reservation notices, dr appt confirmations, tv repair schedule confirmations, delivery notices, etc. She's called the vendors a couple of times, and also called the people directly a a couple times. "You've entered your email wrong, please stop using my email".

One person, one time, understood the situation, thanked her, and updated things. And a year later, we got email for them. There's lots of mischief we could get up to, if so inclined, but we're not like that.

Someone last year accused her of 'hacking' in to their computer and stealing emails, so she's basically given up. But these people are missing their dr appointments, delivery change notifications, etc. And by 'these people', I'm meaning - it's perhaps 4 other people with slight variations of the same spelling.
