Using Postcard APIs to Re-engage Abandoned Carts and Dormant Users

Customer retention and re-engagement are crucial for e-commerce growth. Postcard APIs offer a unique and highly effective solution by enabling automated, personalized direct mail campaigns aimed at recovering abandoned carts and reviving inactive users.

What is a Postcard API?

A Postcard API is an interface that allows businesses to send personalized, printed postcards automatically via an API request. These can be used to target specific user segments with tailored messages.

Why Abandoned Carts and Dormant Users Matter

According to industry research:

• Over 70% of shopping carts are abandoned.

• Dormant users can account for 40–60% of a brand’s database.

Re-engaging even a small percentage of these users can significantly boost revenue.

How Postcard APIs Work

1. Cart Abandonment Trigger: When a user abandons their cart, the e-commerce platform flags this behavior.

2. API Request Initiated: The system sends user details and offer information to the Postcard API.

3. Postcard Generated and Mailed: A personalized postcard is printed and mailed to the user within 24–48 hours.

Benefits of Using Postcard APIs

1. Higher Engagement Rates: Printed postcards have a tangible presence and are less likely to be ignored compared to emails.

2. Personalization and Retargeting: Include the user’s name, product images, and a unique discount code for a highly targeted message.

3. Automated Workflow: No manual intervention required once the API is integrated. Campaigns run automatically.

4. Cost-Effective: Postcard campaigns can cost less than digital ads and generate a higher ROI.

5. Complements Digital Marketing: Works synergistically with email, SMS, and retargeting ads to create a multichannel experience.

Real-World Example

A fashion retailer integrates a postcard API to send abandoned cart reminders. The postcard includes the image of the item left behind and a 10% discount. Within 7 days, 15% of recipients complete their purchase—much higher than the 2% email recovery rate.
