about us

Stop chasing new customers.
Start
keeping them!

Paid ads are getting more expensive. Competition is tougher. That’s why the fastest-growing ecommerce brands win through retention, not just acquisition

At Retention Lab, we build email systems that bring customers back again and again. 🔁

🎯 3 bullet benefits:

- Increase repeat purchases

- Grow email revenue share

- Reduce reliance on paid ads
