How to Ask a Client for a Testimonial by Email
Ask a happy client for a testimonial by email right after a win. Make it easy for them. Give them two or three short questions, or send a draft in their own words to approve. For example: 'Would you be open to a two-sentence quote about [result]? I can draft it from what you told me.' The key is to remove the blank page.
A testimonial lets a client vouch for you to people you'll never meet. Most happy clients are glad to give one. What stops them is not a lack of will. It's a blank page, a busy week and no idea what you want them to say.
The emails that work are short and clear, and they give the client a head start. Offer a few guided questions, a suggested length, or a draft built from their own words. Say where it will appear. Give them an easy way to say no. Most people then reply within days.

Everyone on a rhythm. Who is due, and when. Recorded in the app on a demo account.
1. Right after a successful project, guided questions
Subject: A small favor, [Name]?
Why it works: Three guided questions turn a vague favor into a five-minute task with a clear shape.
2. Asking to quote praise they already sent
Subject: Re: [their original subject]
Why it works: Asking to reuse words they already wrote is the easiest yes you'll ever get.
3. Offering a draft for them to approve
Subject: Draft quote for your approval
Why it works: A draft in the client's own words lets them say yes with one word. The offer to edit keeps it honest.
4. Long-term client, anniversary of working together
Subject: [Number] years of working together
Why it works: Tying it to a milestone gives a natural reason to ask. It also shows them why their voice matters.
5. Asking for a short video testimonial
Subject: Would you record 60 seconds for us?
Why it works: A short time limit, a few prompts and a written backup make a bigger ask feel small.
6. Asking for a LinkedIn recommendation
Subject: LinkedIn recommendation?
Why it works: Pointing to one result keeps the note focused. Offering one back makes it mutual.
7. Asking for a letter or formal reference
Subject: Testimonial letter request
Why it works: A clear deadline, a reason and a few bullets to jog their memory respect their time on a bigger favor.
8. Asking a client who rarely writes long emails
Subject: One sentence?
Why it works: Asking for one sentence matches how this client already writes, so they can answer from their phone.
9. Gentle follow-up after no reply
Subject: Re: A small favor, [Name]?
Why it works: Offering to do the writing removes the last hurdle. The clean way out keeps the bond safe.
10. Asking for an online review after a smaller job
Subject: Would you share a quick review?
Why it works: A direct link makes it a one-minute task. Asking for private feedback first shows you care about the work, not just the stars.

When to send it
- Ask within a week of a clear result. The win and their thanks are both fresh then.
- If a client praises you out of the blue, reply the same day. Ask if you can quote it.
- Don't ask while an issue is still open, a bill is unpaid or the scope is in dispute.
- Send one follow-up about a week later, and then stop.
Subject lines

- Three short questions
What to avoid
- Asking 'Could you write us a testimonial?' with no guidance. That leaves them facing a blank page.
- Posting a quote, an edited version or their full name before they approve it in writing.
- Asking while an issue is still open, or before they've seen a result.
- Sending more than one follow-up. It makes a favor feel like a duty.
- Offering cash or discounts for good reviews. It hurts trust and may break the review site's rules.
- Writing a draft that sounds like an ad instead of the way the client really talks.
After you send it
If there's no reply, send one gentle follow-up about a week later. Offer to write it up from a quick call. After that, let it go. When they send a testimonial, thank them within a day. Send the link once it's live, so they see where their words went. Then keep in touch as usual. Check in every couple of months with something useful for their work. And think of them when you can send a referral their way.

Make the ask about the work you did together Capstone writes the ask from your notes on the project, so it names the real work. You read it, edit it and send it from your own email.

Frequently asked questions
How do you ask someone for a testimonial?
Ask by email, soon after a clear result, and make it easy. Thank them for something specific. Tell them where the testimonial will appear. Include two or three short questions, or a draft built from their own words. Offer to handle edits. Ask for approval before you publish, and give them an easy way to say no.
What questions should I ask to get a good testimonial?
Ask about the before, the after and their advice to others. What was going on before you started? What changed after? What would they tell someone thinking of working with you? These three prompts give a natural story with a clear result. That is far more convincing than general praise.
Is it okay to write a testimonial for a client to approve?
Yes, as long as it reflects what they really said and they approve it in writing. Build the draft from their own words in emails, calls or surveys. Invite them to change anything. Never publish without a clear yes. The goal is to save them time, not to put words in their mouth.
How do you follow up on a testimonial request?
Send one short follow-up about a week later, in the same thread. Say you know they're busy. Offer an easier path, such as a ten-minute call where you write it up for their approval. Say you won't ask again if now isn't the time. Then stop.
How long should a client testimonial be?
Two to four sentences is ideal for a website or proposal. That's enough to name the problem, the result and what it was like to work with you. It's also short enough that people read it. Longer letters suit formal proposals. A single strong sentence works well on a homepage.
