Guys, I also work in IT. There's a couple of parts of that email that make me think its a scam also....
A couple of the sentences just don't make sense....
Surely this sentence is missing the word "could" where i've put the asterisks
"If you are an existing member, we would appreciate if you ***** please provide your membership number in order to update your file"
And this sentence seems to finish early....for both the club and what?
"Your contribution is invaluable at this important time for both the club."
Also parts of the email talk about "we" and some parts "me" - no consistency throughout the email.
Maybe I'm just being way too suspicious, but if i was a betting man, id put my house on it that its a scam
