I have a firstnamelastname@gmail.com address. I get a lot of misdirected emails for others with the same name; usually I ignore them. It's linked to a Zelle account and one day I received an unexpected $500 deposit. I asked my bank if it could be reversed. They said no, but I could return it to the sender by initiating a new Zelle transfer. The transaction only showed the sender's name; I asked my bank if they could provide me with a Zelle address, and they said no, I needed to ask the sender for that information. This was obviously impossible and the whole situation smelled fishy. I let it sit for a few days, and got an email from someone with the same name, asking for their $500 back. It was a lot of money to them, they made a mistake, and their bank wasn't helping them recover it at all. I couldn't decide if it was a scam or not. I ended up sending $500 to the address I received the email from. They thanked me profusely, and I never heard about it again.
