When to send it
For an online store, the best moment for this survey is a week or two after an order has been delivered. By then the customer has unpacked it, used it a little and formed a view of your shop as a whole, not just of the parcel. If your volume is low, send it after every delivered order. If you already run a first order check-in for newcomers, send this one from the second order onwards. On Shopify, add the link to your order email from the Integrations page: the order number then travels with each answer as ?ref=, so you can find the order behind a low score.
Why these questions
The opening question is the usual 0 to 10 recommend question, reworded to say "our store" so customers think about the shop rather than one product. Hearsay sorts the scores into promoters (9–10), passives (7–8) and detractors (0–6) and calculates the result in analytics.
The second page is what makes this version useful for a shop. It asks how the most recent order went, with a short list of the usual culprits: slow delivery, a problem with the product, a fiddly checkout. A low score often has a simple cause in one bad order, and this question separates "I don't like your products" from "my parcel turned up a week late". Anyone who picks a problem gets a box to describe it.
The last question asks for the main reason behind the score, in the customer's own words. It's optional, yet it's where the most quotable sentences come from.
Customers who reported a problem with their order land on a separate end screen that apologises and promises the answer will be used. Everyone else sees a plain thank-you. Both screens carry the same 10% code, because it pays for the customer's time and has nothing to do with how high they scored you.
What to do with the answers
In the responses list, read each detractor's score next to what they said about their last order. If detractors cluster around delivery, the fix sits with your courier or your dispatch times, not your product range. If they cluster around the product, look for one item or size that keeps coming up. Where an answer carries an order number, open that order and write to the customer yourself.
Follow the score month by month rather than reacting to a single week. For a closer look at individual purchases, pair this with purchase satisfaction (CSAT). For the standard version without the order question, use NPS with follow-up.
