When to send it
This is a general satisfaction check for any order, whether it's a customer's first or their twentieth. Send it once the order has arrived and the customer has had a day or two with it. For first-time buyers, the first order check-in goes further into what nearly stopped them buying; this survey suits your regular flow of orders and is short enough to send after each one. If you're on Shopify, the order email link from the Integrations page passes the order number along as ?ref=.
Why these questions
It opens with the standard CSAT question: overall, how satisfied is the customer with this purchase, from 1 (very dissatisfied) to 5 (very satisfied). That gives you one number to follow from month to month.
An overall score hides where things went right or wrong, so the second question is a small grid. The customer rates four parts of the purchase, the product, value for money, delivery and checkout, each from poor to great. It takes seconds and shows at a glance which part drags the overall score down.
Customers who give a 3 or lower see a follow-up asking what fell short. It's optional on purpose: someone who has already told you they're unhappy shouldn't have to write an essay to reach the end.
The last question asks whether they would buy from you again. It's a behavioural check next to the satisfaction score, and the two don't always agree. A customer can be perfectly satisfied and still see no reason to come back.
The coupon
A shared 5% code appears on the thank-you screen for everyone who finishes. It's a modest thanks that suits a one-minute survey, and keeping it small means regular customers don't learn to wait for a discount before ordering. If you'd rather push second orders harder, the first order check-in uses unique codes for a bigger saving.
What to do with the answers
Look at the grid first. If delivery trails the product, the issue is logistics, and the delivery experience survey can dig deeper. If value for money is the weak row, that's a pricing or positioning question worth settling before your next sale.
Then read every answer to "what fell short", and set the buy-again answers against satisfaction. Customers who are satisfied but unsure about ordering again are the group a well-timed follow-up email or a new product launch can win over. Customers who are unhappy and say they won't return deserve a personal reply if the order reference lets you reach them.
