They've got another five hundred and fifty to go, this could be quite boring.
Spam starting like this is like finding a couple of ants in the kitchen - you know there's going to be more along shortly.

[Raak] Please could you remind me of your email address (obfusc. as necessary). I've largely rewritten my, er, mathematical thing for the Summer of Math Exposition, and I think the new version is significantly more convincing. Even though you never said you'd seen anything wrong with the old one... My offline email database is currently extra-offline thanks to a hardware failure.

My first is in Richard, and so're the next six
An at sign; the next begins kerning, and kicks
The next starts elopement, and is most of epee
Then the middle of and, and the start of "no way!"
That letter once more, and then half of an aa
And a "way" to complete it; if you're with me thus far
A dot and an org and a dot and an uk
And that is the whole of the handle — good luck!

Bonus clue: I'm probably distantly related to these people

I tried asking ChatGPT 4o to decode that, and it couldn't quite manage it.

I’d have got it wrong; I assumed way = rd!

Lovely. That should be the standard way to obscure email addresses.
