Put together a really nice automation routine for a client recently.
The client needed a way to fully automate abandoned basket reminders.  But the key is they only wanted to send the reminder X number of times.
Thanks to some code from a few previous projects, I was able to put together a modification that changed only 1 existing AbleCommerce file.
Now their AC7 store will automatically scan for abandoned baskets at regular intervals.  Any baskets found are sent the designated email.  Once the email is sent, a marker is placed on the basket so the shopper isn’t spammed with reminders.  Even wrote a handy config page so the client can adjust the designated email template or the criteria without further program customization.
