What is an Abandoned Cart?
When you click on the "Abandoned Carts" button in your Orders page, you will toggle your view to show Open Order drafts that were started by Buyers more than 2 days ago which have not yet been placed.
This allows you as the Seller to get a bit of insight into your Buyers' activity, so you can decide if you'd like to reach out to the Buyer to encourage the Order.
Please remember that these are just drafts and that the Buyer may not be ready to proceed with the Order just yet.
If you wish to reach out to your Buyer regarding this order, you can click the "Recover Cart" button inside the Order to send them a custom message.
See Recover Abandoned Cart for more info.
