Recover purchases where the customer left their email in checkout but did not order. The three email variation sends an initial reminder as the first email, before offering a time sensitive discount coupon to use on the purchase in the second email. There is one follow up email the initial coupon send to remind the customer to use it before it expires. The flow automatically removes any customers that make a purchase during the email sequence to avoid excess email fatigue.
Engaging with new customers is a must if you plan on building a long-term relationship with them. The Post Purchase flow allows you to just that. It should not be confused with an Order Confirmation message (that is sent separately by your eCommerce platform) but is instead an opportunity to begin sharing brand and product information, providing helpful tips or FAQs, and to eventually upsell and cross-sell the customer on other products in your store.
