Based on the 24-48 hour post-delivery window that consistently outperforms earlier or later sends. See why timing matters this much for the reasoning.
Why this matters
Timing moves response rate more than almost anything else
A survey sent too early asks about an experience the customer hasn't had yet. One sent too late asks them to recall a fading impression. The 24-48 hour window after delivery is where both a fresh reaction and a completed delivery overlap.
At scale, this means triggering off a delivery or fulfillment event, not an order date - see how this works for Shopify merchants.
Common questions
Survey timing, answered
When should I send a post-purchase survey?
In the 24-48 hours after the product is delivered, not at order time. Timing it to the delivery event captures a fresh reaction before it fades from memory.
Why not send the survey right after checkout?
A survey sent at checkout asks about an experience the customer hasn't had yet. It measures purchase satisfaction, not product satisfaction.
Why not wait a few weeks, like a review request usually does?
By then the impression has faded and the response rate drops. Post-purchase feedback works best close to the moment of delivery, while the reaction is still fresh and specific.
What if I don't have exact delivery tracking?
Use your average transit time for the shipping method as an estimate - it doesn't need to be exact, just close enough to land the survey inside the 24-48 hour window.
