M&S credit card

I applied for an M&S credit card earlier today, and have received an emailing confirming that I have been accepted. The thing is, the email doesn't look right, it's from a random email address @hsbc.co.in, there's no branding on it at all.

Has anyone else applied online and got a dodgy looking email? It doesn't ask me to do anything, just wait for my documents by post.

TIA
