Abandoned cart emails are emails that are sent to customers who added items to their cart, but then never completed the checkout process. It’s used by businesses to convert prospects into paying customers. When creating such an email, you’ll usually include a catchy subject line, introduction, list of the items that are waiting in the cart, and a call-to-action prompt. If you want to, you can also include a discount or offer as an extra incentive or just social proof, like a product review, for encouragement.
