I've seen about this before, someone with the same name as you accidentally puts your email address down instead of theirs. Usually it's because there is a . involved and missed.
A few months ago I got an email from the police thanking me for my report about a covid breach (I emailed back saying the name was correct but I had not reported anyone).
Now to today. I apparently have purchased and insured a dog in America, I've also signed up for alerts for all missing dogs in the area!!! Again we have the same first name and last name, but I live in the uk and definitely don't own a dog! This is one of them emails that you cannot reply too, and the number is (of course) American. I am not calling America, so the alerts will stay. (I've had 6 emails in the last hour about registering the dog, what dog it is and how I've set these alerts up!
