I strongly recommend trying Soundest and it's Cart Recovery Series. It's much more effective than abandon cart emails. Instead of one abandoned cart email you can set up a Cart Recovery Series and send three emails in the row via 48 hours. Emails have different, personalized titles, so if customer haven't opened the first email, there is a high probability that the second or third letter will certainly be opened. Instead of the 12-15% of recovered carts achieved by other services, Soundest retains up to 20% of customers and it have their own API and WooCommerce integration, so you won't get any errors.
