The flow

Three messages over 48 hours. Stops the moment the customer either checks out or replies. Most stores see roughly 12 to 18 percent of abandoned carts recovered with a sequence this size.

Why three

One email recovers about 8 percent of abandons. The second email adds another 4 to 6 percent. The third adds another 2 to 4. Past three, the diminishing returns are real and unsubscribe rates climb fast enough to lose the win.

Why 48 hours

The cart-abandonment recovery curve is steep — 80 percent of recoveries happen inside the first 24 hours. Past 72 hours, response rates drop to noise. We compress the sequence into 48 hours to capture the steep part of the curve and stop before the customer is annoyed.
