You can view abandoned Partially checkouts in order to manually send individual rescue messages, in case you have not configured Partially to automatically send rescue messages. Go to the Abandoned Checkouts link in the Abandoned Cart menu to see a list of payment plans in checkout status.
From there, when you go to a payment plan you can click on the Abandoned Cart tab to see a list of rescue messages that have been sent
To send a rescue message, click on either the Send rescue SMS or Send rescue email button. Note that the send Rescue SMS button will only be visible if the customer has entered a phone number, and the Send rescue email button will only be visible if the customer has entered a valid email address. After clicking one of the buttons, you'll need to select an offer to send with the rescue message. Sending the customer a better offer will improve your chances of rescuing the checkout.
