We get a few failed card payments.
Sometimes the customer fixes it, sometimes they walk away and we aren't sure if they have given up or think it was successful.
It would be easy enough to create a email plugin that checks for a failed payment that wasn't then followed by a successful payment and sends an email saying "Sorry your payment failed... perhaps with some tips about why (our most common reason is bill payer address was wrong." However
What I'd really like is to include a link that takes them back to the check-out for that transaction...
