# How to ask customers for reviews, and actually get them

Ask once the customer has used the product, make it one tap with media invited by name, follow up once: most under-collection is timing and friction, not refusal.

The post-purchase email opted 9 percent of recipients into leaving a review. Rewrite one sentence and the same email hit 28 percent. The sentence that moved the number is in the third draft below, and it is shorter than the one it replaced.

**Quick answer**

- Low review rates are usually an ask problem, not a willingness problem.
- Timing matters most: ask once the customer has used the product and formed an opinion.
- The ask must be effortless: one tap, no account, photo and video optional but invited.
- Incentives can help, but only when disclosed and structured so they do not buy positive reviews.

When review volume is thin, the easy story is "our customers do not leave reviews". Usually they would have. They were asked at the wrong moment, in a clumsy way, or never clearly asked at all.

## When should I ask for the review?

Ask too early and the customer has no opinion yet: the product has not arrived, or has not been used. Ask too late and the moment has gone. The window opens in the days after the customer has actually used the product and formed a view, long enough to have an opinion, soon enough to still care.

## The ask that works

1. Send it at the right moment, triggered off delivery plus a usage gap, not off the order date.
2. Make it one tap: straight into the review, no login, no long form.
3. Invite media by name: "a photo or short video helps other shoppers" lifts [the visual-review rate](/blog/photo-video-reviews-vs-text-reviews).
4. Keep it personal and short: a human, specific message, not a generic blast.
5. Follow up once. A single gentle reminder, never more.

## What kills review rates?

- A long form, or one that demands an account.
- Wrong-moment timing, before the product has been used.
- No reminder, or too many.
- No visible reviews on-site: customers will not contribute where contribution looks pointless.

## Which channel should the ask go out on?

The channel matters less than the timing, but it is not neutral. Email is the workhorse: cheap, threadable, and easy to trigger off a delivery-plus-usage gap, which is why most review asks live in a post-purchase flow. [SMS and WhatsApp](/blog/sms-and-whatsapp-social-proof) pull a higher response on the first touch because they land where the customer already is, but they punish over-use fast, so they suit the single ask and the single reminder, not a sequence. An on-site or in-app prompt catches the customer who is already back looking at the product, which is a quiet signal they have an opinion worth capturing. The strongest setups pair an email ask with one cross-channel reminder rather than blasting all three, and they route the reply straight into the same place the proof gets surfaced, which is the loop covered in [UGC in email and Klaviyo flows](/blog/ugc-in-email-and-klaviyo-flows). The review and the media it carries then feed the on-site galleries described in [above-the-fold social proof](/blog/above-the-fold-social-proof).

| Channel | Strength | Watch out for |
| --- | --- | --- |
| Email (post-purchase flow) | Cheap, easy to time, threadable | Easy to ignore; needs a strong subject line |
| SMS / WhatsApp | High first-touch response, lands where they are | Over-use kills it; one ask, one reminder |
| On-site / in-app prompt | Catches the returning, opinionated shopper | Misses customers who do not come back |
| Packaging insert / QR | Arrives with the product itself | No timing control; fires before first use |

_Where the review ask lands best, by channel._

> **Incentives, done right:** A small incentive can lift response, but it has to be disclosed, offered for a review whether or not it is positive, and never conditioned on a star rating. Incentivised reviews dressed up as organic, or rewards that buy positivity, breach FTC/ASA rules and erode the trust the reviews exist to build.

**The collection rule:** Ask at the moment the customer has an opinion, make responding effortless, and show that reviews get used. Volume follows.

> **How Idukki helps:** Idukki collects reviews and customer media at the right post-purchase moment and surfaces them on-site, so customers see their contributions used, which feeds the next wave.
