I have to say I find an unsolicited e-mail like this a tad interesting,
even worrying. Did anyone else get it? Does anyone know if this is
just a bright idea from someone or have they had a problem somewhere and
doing a bit of CYA?

I think it might be a warning shot about sites like this:

http://www.chromaroma.com/

That use your Oyster login...

It might well be but the question OP is asking is how TfL knew his
e-mail address if he has not registered his Oyster card.

(My suggestion is that maybe the unsuccessful attempt to register got
as far as adding the e-mail address to the TfL database.)
