1. Send confirmation email or SMS: After the customer completes the payment, send an email or SMS confirming the order immediately. The e-mail or SMS should contain information such as order details, payment amount and estimated delivery time.
2. Provide order tracking information: If the product or service needs a certain delivery time, ensure that customers can track their order status after purchasing, and provide an order tracking link or method to let customers know where the order is at any time.
3. Provide customer support information: provide contact information of customer support in the confirmation email, such as customer service phone number, e-mail address or online chat.
4. Offer a thank-you discount: attach a thank-you coupon or special discount to the confirmation email to encourage customers to buy again, which can also increase customers' loyalty to the brand.
5. Regular update: keep in touch with customers during order processing or after delivery, and send order status update or delivery reminder e-mail to keep customers interested and satisfied.
