So I've managed to get the same e-mail from Spotify six times in the last 4 hours. It's an e-mail recommending the same 8 artists / albums. They all have different Message-ID headers and different Time/Date stamps on them so I know it's not my mail client being wierd. I've tried unsubscribing and resubscribing to notification in my account, but they still keep coming. Anyone else experiencing this?
