‘Let them know’ scam or prank

Hi everyone, I received this email from something called « Let Them Know Service » saying I may have been exposed to chlamydia and should get tested. But here’s the thing I’m a virgin and have never had any kind of sexual contact, so I know for a fact I can’t have chlamydia.

Is this some kind of scam or phishing attempt? Has anyone else gotten something like this?

I’m based in the UK and the email mentions Melbourne, Australia, but I don’t live there either, which makes it even weirder.

Any advice would be appreciated!
