I'm having the team check. My guess is that it's an account that previously should have received the alert and we fixed a bug to enable the alerts to come through. That said, the guys were specifically told not to send the old ones!
Peter Hazlehurst: Thanks for your comment! You have always been very responsive, especially when I write about Yodlee on my blog. I checked my old Email and found that in many cases I had received the Yodlee alert before, and then again this past weekend. I was very surprised when I opened up my Email and found that so many Yodlee alerts came in at once.
but we think that's the reason.
Peter: You are correct. I noticed some very minor differences in the transaction description between the original and most recent alerts that I received.
