How should eco DTC run post-purchase surveys for attribution and product truth?
Quick answer
Run a short post-delivery survey that captures how buyers found you and whether the product fit, then feed answers into channel and product decisions. Keep it 3 to 5 questions. Pair with incrementality, first-party data, and retention.
Two jobs, one short survey
- Attribution: how they found you (multi-select + free text)
- Product truth: fit, expected vs actual, packaging, likelihood to repurchase
Optional third: content that helped decide (reviews, comparison pages, quiz). Do not ask ten brand-tracking questions on order day.
Timing
| Touch | When | Focus |
|---|---|---|
| Light attribution | Order confirmation or day 1 | Channel multi-select only |
| Core survey | 3 to 14 days after delivery | Fit + attribution refresh |
| Skip | Open tickets / returns | Suppress until resolved |
Question set (example)
- How did you first hear about us? (multi-select: Instagram, Google, friend, podcast, retailer, other)
- What almost stopped you from buying?
- Did the product match what you expected?
- Anything about packaging or materials you want us to know?
- Would you buy again / refill? (scale)
Close the loop
- Tag profiles for CRM segments (podcast buyers, retail discovery)
- Roll up weekly channel mix vs media reports
- Send product themes to merchandising and claims owners
- Do not treat survey attribution as perfect truth; triangulate with incrementality
Measurement
- Response rate and completion time
- Top attributed channels vs paid spend
- “Did not match expectations” rate by SKU
- Actions taken from insights (creative, PDP, claims)
Ask, then act
Surveys only create value when channel and product teams change something.
Frequently asked questions
When should the main survey send?
After delivery and early use, usually within 3 to 14 days depending on the product.
Is “how did you hear about us” enough?
It is directional. Combine with media mix and incrementality tests.
How long should the survey be?
Three to five questions. Longer surveys tank completion.
Should we incentivize responses?
Optional small thank-you is fine; do not pay for flattering answers.
Who owns the insights?
Growth owns attribution rollups; product owns fit themes. Meet weekly.
