I was looking for a way to email a customer after they've abandoned the cart asking if they had any issues and reminding them to return to site and complete the checkout process.
This module seems to be exactly what I am looking for but sadly it looks abandoned and it does have considerable amount of bugs reported (in comparison to total installations number)

Does anyone have any other more stable recommendations? I was thinking that perhaps this could be done with rules....
