Over time, Sal notices that a number of shoppers start the check-out process, but don’t complete their accessory purchases. What are some ways he can encourage these specific shoppers to return to complete their purchases?

Abandoned cart emails are specifically designed to re-engage shoppers who initiated the checkout process but didn't complete their purchase. Including a promo code provides an additional incentive for them to return and finalize their order, directly addressing the problem Sal identified. An automated welcome series is for new subscribers, not those who abandoned a cart. Organic social posts are a broad marketing tactic and don't directly target specific abandoned carts. An email campaign targeting high-purchase likelihood customers is a good strategy for general sales but doesn't specifically address the abandoned cart scenario.
