A phishing attempt was my first thought, however, all looked legitimate. Just to be on the safe side, I logged into my account without following the link in the email and looked at the last payment.
The amount of the last payment (which had already been processed by the bank) changed (increased).
I'm OK with that, just wish I knew why :)
