Almost all of the value in a satisfaction response comes from knowing what it is about, and that is a property of how the survey was sent rather than anything you can recover afterwards.
Key takeaways
The survey link carries an order token, not just a customer identifier.
That means a response arrives already attached to a specific transaction.
Anonymous responses are kept and counted but cannot be followed up, and that is stated.
Ask once per order, not on a schedule, and never twice about the same thing.
The timing of the ask changes the score more than most people expect.
Token the order, not the person

Why the order and not the customer
A response attached to a customer tells you somebody is unhappy. A response attached to an order tells you which experience they are unhappy about, which is the difference between a reply that asks what went wrong and a reply that already knows.
For a customer with one order the distinction is academic. For a repeat customer it is the whole thing: “sorry to hear that, can you tell me more?” reads very differently from “I can see the 14th arrived two days late — that is on us.”
Two caps, both needed
One ask per order prevents asking twice about the same experience, which is annoying and produces contradictory data. A frequency cap per person prevents a customer who orders weekly being surveyed weekly, which is how a business trains its best customers to ignore its emails.
Neither cap on its own is sufficient, and the frequency cap is the one usually missing. Sixty days is a reasonable default: a customer is asked about at most one order every two months regardless of how often they buy.
Timing the ask
Order type
Ask after
Why
Delivered goods
2 days after delivery
Long enough to have opened it
A service visit
Same day, that evening
While it is fresh and specific
A long project
At completion, then never
Mid-project surveys measure mood
A subscription
Never per order
Ask twice a year instead
Asking too early produces a score about the ordering experience; asking too late produces a score about how they feel in general. Neither is what the survey is for, and the interval is worth setting per order type rather than globally.
Anonymous responses

Front-end & mobile
Anonymous responses skew low, consistently, because somebody moved enough to seek out a feedback widget is more often unhappy than the average recipient of a survey email. Blending them into one score produces a number that moves for reasons nothing to do with the business.
