Hm. I don't think I've told that story over here. It's a couple of years old, but still.
Background: My personal vanity domain is mw.mw. I receive many emails there.
This leads to a lot of extra mail from places that don't bother verifying emails, like linkedin, CVS, and other random orgs.
But in 2019 I got emails behalf of CISA thanking me for the participation in the 2nd Annual National Cybersecurity Summit, with a survey link and all.
Cybersecurity tip: Don't use real emails for testing.
