The best time to ask for a review is after the customer has used what they paid for: 3–7 days after purchase for an instant digital product, 7–14 days after delivery for most physical goods, 24–72 hours after a one-off service, and 30–60 days after the first payment for a SaaS subscription. Send it on a Wednesday or Saturday, the days PowerReviews found convert best, between 10am and 2pm, the window it suggests as a starting point. Then remind twice and stop.
Too early and the customer has no opinion yet. Too late and the purchase is a distant memory. The sections below break the timing down by business type, day of week and reminder cadence.
The golden rule for the best time to ask for a review
The universal principle: don't ask for a review until the customer has received and experienced what they paid for. Obvious, but widely violated. E-commerce stores that send review requests 24 hours after ordering, before the product has shipped, get low response rates and worse reviews, because the customer hasn't used the product yet.
For every business type, the question is: when has the customer experienced enough to have a meaningful opinion?
By business type
Digital products & SaaS
| Product type | Optimal timing | Why |
|---|---|---|
| Instant-access digital product (e-book, course, template) | 3–7 days after purchase | Enough time to consume, not so long the purchase feels distant |
| SaaS (free trial) | 7–14 days into the trial or immediately after first "aha moment" | Capture impression while engaged, but after the product has delivered value |
| SaaS (paid subscription) | 30–60 days after first payment | Give time for onboarding + habitual use; renewal is a natural trigger |
| Software update / new feature | 14 days after feature adoption | User has integrated the change into their workflow |
The SaaS nuance: Subscription businesses have recurring verification opportunities. Don't just ask once, every renewal payment is a new transaction and a new chance to ask. A customer who's been subscribed for 12 months has a fundamentally different perspective than one who's been subscribed for 2.
Physical products
| Product type | Optimal timing | Why |
|---|---|---|
| Standard e-commerce (in-stock) | 7–14 days after delivery | Product received + used + opinion formed |
| Made-to-order / custom | 14–21 days after delivery | Longer experience curve before the product is "lived with" |
| Clothing / fashion | 5–10 days after delivery | Quick opinion formation, but allow for returns window awareness |
| Electronics / high-consideration | 14–30 days after delivery | Takes time to evaluate; early reviews skew superficial |
| Consumables (food, supplements) | 7–14 days after delivery | Quick consumption cycle |
The delivery trigger: If you have access to tracking data, the ideal trigger is N days after the carrier confirms delivery, not N days after the order is placed. A product that takes 10 days to ship shouldn't trigger a review request on day 3.
Services
| Service type | Optimal timing | Why |
|---|---|---|
| One-off service (cleaning, repair, consulting session) | 24–72 hours after service completion | Fresh but not raw; immediate post-service asks feel pushy |
| Recurring service (monthly cleaning, ongoing consulting) | After the 2nd or 3rd engagement | First session isn't representative; give the relationship time to stabilize |
| Professional services (legal, accounting, agency) | At project milestone or completion | Natural breakpoints, not calendar-arbitrary dates |
Day of week and time of day
PowerReviews analyzed hundreds of thousands of review requests sent by its clients. Its findings:
- Best days: Wednesday and Saturday had the highest conversion rate for review request emails. Other days still work.
- Best time of day: 10am–2pm in the recipient's timezone, as a starting point. It catches people on their lunch break. PowerReviews names 6pm as a second peak.
- Then use your own data: once you have a few months of sends, your own email analytics beat any general rule.
- Avoid: late-night sends, which feel automated and impersonal.
Reminder cadence
Most people don't write a review on the first request. A short, structured reminder sequence gives them more chances to respond without pestering them:
| Send | Timing | Notes |
|---|---|---|
| Initial request | Optimal window (per chart above) | Friendly, personalized, clear CTA |
| First reminder | +3 days | "In case you missed this", light, no guilt |
| Second reminder | +7 days (10 days total) | Final ask. "Last chance" framing. After this, stop. |
Stop after 2 reminders. Each extra email risks annoying the customer you want a fair review from. If someone hasn't reviewed after 10 days and two reminders, they probably won't.
Transaction-verified: why the best time to ask for a review matters even more
With processor-attested (Level 4) verification, review requests are tied to specific Stripe charges. That means:
- You can't send a request without a real charge. No "batch-invite everyone in my customer list." Every invitation traces back to a confirmed transaction.
- Timing is deterministic. The invitation goes out when the charge comes in, or after the delay you set, not when you remember to send it. For physical products, set a delay that covers shipping. See how it works for the full verification flow.
- Refunds auto-hide reviews. If the charge is fully refunded or disputed after the customer leaves a review, the review is hidden automatically. Charges are re-checked every 6 hours, and partial refunds stay visible. So you don't need to worry about reviews from customers who ultimately weren't satisfied.
The net effect: processor-attested review collection encourages you to get the timing right upfront, because every paying customer gets the same invitation sequence and you don't hand-pick who is asked. The system is neutral: it sends to every paying customer, at the best time to ask for a review, without you curating the list. See pricing for plans with automated review timing.
What NOT to do
- Don't ask before the experience is complete. Pre-delivery review requests generate low response rates and lower-quality reviews.
- Don't send more than 2 reminders. By the third, the request starts to feel like pressure.
- Don't gate reminders behind positive sentiment. Selectively reminding only happy customers is invitation bias. The FTC's guide for marketers says: "Don't ask for reviews only from customers you think will leave positive ones."
- Don't offer incentives for positive reviews. Incentives for writing a review are generally fine (if disclosed). Incentives for writing a positive review are not: the FTC's 2024 rule bans incentives conditioned on a review expressing a particular sentiment.
- Don't batch-send to your entire customer list at once. Staggered, transaction-triggered sends get higher response rates and feel personal.
The bottom line
The best time to ask for a review is when the customer has experienced the full value of their purchase, which varies by what you sell, and on a Wednesday or Saturday between 10am and 2pm. Send once, remind twice, stop. And whenever possible, tie the invitation to the transaction itself, so every paying customer is asked at the right time without you having to manage the timing manually.
