What are abandoned cart emails? Essentially, this is a marketing channel that you can use as a shop owner to win back the otherwise lost sales. So this is a very specific set of emails. You send two potential customers that were on your checkout page and for some reason they got a phone call, they got call feed, whatever it is, they didn't complete the checkout and you send them those emails, like 10 minutes after they left the checkout, then you remind them another four hours, maybe on the next day, again, you incentivize with discounts and things like that to win back, let's say it.
