Customers will still receive the first abandoned cart email if they reach the checkout page and enter their email address but do not complete the order. The email will contain all campaigns that were in the customer’s cart. If the customer makes any changes to their cart, but still does not complete the order, they will receive the same abandoned cart email with their changed cart.
If the customer does not make a purchase after receiving the first abandoned cart email, they will receive a second abandoned cart email on the day when a campaign that is in their cart is ending. That email will contain just the single campaign that is ending.
