Hi guys,
I think, your email with Daily Deals needs to be changed somehow. I do not know the technicalities, but Yahoo somehow fails to refresh the content of the email. The daily deals are not refreshed: e.g. I see the yesterday's deals in the email.
Please test it with Yahoo web mail: there is something in your emails that fools Yahoo to not refresh the content but take it from their cache servers somewhere.
It is very annoying: I am even thinking to unsubscribe from the deals because of this bug.
