What's a Good Response Rate for a Post-Purchase Survey?

“Is our response rate good?” is one of the first questions any team asks once a post-purchase survey is live. Short answer: most land somewhere between the low single digits and 20%, and there’s no single number that applies across channels. The longer answer is that it varies a lot by format, and there’s a more important question hiding behind it.

Rough Benchmarks by Channel

As general industry reference points, not a guarantee for any specific brand:

• Email surveys typically land in the low single digits to around 15-20%, depending heavily on list quality, subject line, and how trusted the sender is.
• SMS-based surveys tend to see meaningfully higher engagement than email, often because they’re shorter by necessity and read faster.
• In-app or post-checkout prompts can reach higher completion when shown at a moment the customer is already engaged, though they reach a narrower audience than email or SMS.

These ranges move a lot based on industry, audience, and execution - treat them as a rough compass, not a target to hit exactly.

What Actually Moves the Number

Response rate is driven far more by execution than by channel choice alone:

• Timing - a survey sent in the 24-48 hour window after delivery consistently outperforms one sent weeks later, when the experience has faded from memory.
• Length - each additional question after the first few measurably reduces completion, as covered in how to write a survey that gets answered.
• Relevance - a survey that names the specific product a customer bought reads as more worth answering than a generic brand-wide prompt.
• Sender trust - a survey that looks like it comes from the brand the customer just bought from converts better than one that looks like generic marketing.

Response Rate Isn’t the Real Metric

A high response rate from a biased sample is less useful than a moderate response rate from a representative one. If a survey is only reaching the most engaged repeat customers, a high completion rate is measuring enthusiasm, not the average experience. The more useful question isn’t “how many people answered” - it’s “does the group that answered look like our actual customer base.” A structured, delivery-triggered survey sent to every customer, not just the most engaged ones, is what makes the response rate number meaningful in the first place.
