It arrives with no warning: an email, a Slack message, a line at the end of a support thread — "Honestly, this is the best purchase we've made all year. Your team saved us this quarter." No survey prompted it, no ask preceded it. It's the most genuine praise you have, and it's sitting in a private inbox where exactly one person will ever see it. Unsolicited praise is the highest-quality raw material for a testimonial precisely because nobody engineered it. But a compliment in a DM is not yet a testimonial — and how you handle the next twenty-four hours decides whether it becomes one.
First, respond as a person — not as a marketer
The instinct to reply "Thank you! Mind if we use that on our site?" is understandable and slightly wrong. Lead with genuine appreciation and nothing else, first. The customer did something generous and unprompted; meeting it immediately with an ask reframes their gift as a transaction and can make them wish they'd stayed quiet.
Reply warmly, specifically, and without an agenda: "This genuinely made our week — thank you for taking the time to say it. I'm glad the reporting piece landed, that's exactly what we built it for." That's the whole message. The permission conversation can come in a follow-up, or a day later. Separating the thank-you from the ask keeps the moment honest and, paradoxically, makes the customer far more likely to say yes when you do ask.
Get explicit permission — always, even for a public post
Praise sent to you privately is not permission to publish. A customer who fires off an enthusiastic email is speaking to you, not to your homepage, and using it publicly without asking can turn a fan into someone who feels exposed. This holds even when the praise appeared somewhere semi-public, like a tweet or a LinkedIn comment — visibility in one context is not consent to feature it in another.
The ask itself can be light, because you're not requesting new work — you're asking to share something they already wrote:
- "That note meant a lot — would you be comfortable if we quoted it on our site? Exactly as you wrote it, with your name and title, and I'll send you the final placement before it goes live."
- Name what you'll attribute: full name, title, company, photo or logo — so there are no surprises. If they'd rather stay partly anonymous, honor it.
- Offer the veto. "Send you the final before it goes live" costs you nothing and removes the last reason to hesitate.
Because the customer volunteered the praise, the yes rate here is far higher than a cold testimonial request. You're not asking them to manufacture an opinion — just to let more people see one they already held.
What you may edit, and what you may not
The words are theirs; the presentation is yours. That line governs every change you're tempted to make. You may trim for length, fix an obvious typo, or cut a sentence that wandered off-topic. You may not add claims, sharpen adjectives, or insert specifics the customer didn't say. If their raw note reads a little loosely, tightening it is fine — the same care that governs editing a testimonial for grammar applies: adjust presentation, never substance.
One caution specific to unsolicited praise: it often arrives casual and generous but vague — "best tool all year" with no concrete result. Resist the urge to invent the specifics it's missing. If the quote would be far stronger with a number, that's a reason to reply and ask the customer for the detail, not to write it in yourself. A real vague quote beats a fabricated specific one every time — invented detail is exactly what makes testimonials sound fake and quietly poisons the credibility of everything around them.
Place the gift where it does the most work
An unsolicited testimonial usually carries unusual emotional weight — it wasn't coaxed, so it reads as spontaneously true. Don't bury that in a rotating carousel. Give it a prominent, static slot: near a primary call to action, on a pricing page, or beside the exact feature it praises. If the customer is a recognizable name, the placement matters even more, because the logo and the unprompted warmth reinforce each other.
Keep the date on it. A recent, dated quote signals current relevance, and a visible date is part of what makes a testimonial read as real rather than staged — the same effect behind date-stamped testimonials being more credible. Handled well, a message you never asked for becomes one of the most persuasive assets on your site — because the reader can feel that nobody made the customer say it.
The short version
When praise arrives unbidden: thank them first as a human, ask for permission separately and explicitly, edit only presentation and never substance, ask for missing specifics rather than inventing them, and place the finished quote somewhere it can be seen. The strongest testimonials are the ones you didn't have to pull out of anyone — your only job is to not fumble the gift.
