How to ask for a testimonial over email
Email is still the most effective channel for collecting testimonials. The trick is getting the timing, subject line, and ask right. Here’s exactly how to do it.
The ideal timing for asking
Timing is everything. Ask too early and the customer hasn’t felt the value yet. Ask too late and the enthusiasm has faded. These are the moments when a customer is most likely to say yes.
Post-purchase (2–4 weeks)
For products with a learning curve, wait until the customer has had time to see results. For simple products, a week is enough. The sweet spot is when the novelty is still fresh.
After a positive support interaction
This is your #1 ask moment. When a customer says "thank you, that fixed it" — reply with a link. The gratitude is reciprocal and the sentiment is at its peak.
At customer milestones
Renewal anniversaries, 100th login, first project completion — any milestone triggers reflection. Customers feel accomplished and are more willing to share.
Email subject line examples
The subject line determines whether your email gets opened or ignored. Keep it personal, curiosity-driven, and short. Here are five that work consistently.
- 1Quick question about your experience with [Product]
- 2Would you mind sharing a few words about [Product]?
- 3How has [Product] been working for you?
- 4Your feedback on [Product] — 2 minutes is all it takes
- 5Loved having you as a customer — would you share that?

Following up without being pushy
Wait 3–5 days before the first follow-up
Most people intend to reply but genuinely forget. A single follow-up gives them the nudge they need. Sending it sooner feels desperate; later feels disconnected.
Keep the follow-up short and light
"Just circling back in case this got buried" is all you need. Don't re-explain why testimonials matter — they already know. One paragraph max.
Never follow up more than twice
Two unanswered emails means they don't want to (or can't) respond right now. A third email annoys rather than persuades. Move on and ask again in 6 months.
Give them an easy out
Phrases like "no pressure at all" or "if now isn't a good time, no worries" remove guilt and preserve the relationship. A gracious exit leaves the door open for later.
Using a testimonial collection link
The single most effective thing you can do is put a collection link in every email. A collection link opens a simple page where customers can type a testimonial or record a short video — no account needed. With Vouchnest, you get a unique collection link per space that you can share anywhere.
Create a space
Name it after your product, customise the form.
Copy your link
Share it in email signatures, receipts, or post-purchase emails.

Review, approve, and embed in one click.
Frequently asked questions
How long should the email be?+
Keep it under 150 words. A short, personal email performs better than a long, formal one. Your goal is to make the ask in as few sentences as possible while still being warm and polite.
Should I offer an incentive?+
It depends. For B2B or high-ticket products, a small discount or gift card can boost response rates. For most SaaS products, customers are happy to help without one — just make sure you make it easy. If you do offer an incentive, mention it in the email.
What if they say no?+
Thank them anyway and move on. A polite "no problem, thanks for considering it" preserves the relationship. You can always ask again in 6–12 months. Never pressure someone who declined — it damages trust.
Can I automate this?+
Yes. Email sequences (via tools like Customer.io, Klaviyo, or ConvertKit) can send a testimonial request automatically 30 days after purchase with a follow-up 5 days later. See our guide on <Link href="/how-to/automate-testimonial-collection" className="ink-underline">automating testimonial collection</Link>.
Should I ask for video or text?+
Offer both. Some customers prefer typing, others prefer recording a quick video. A tool like Vouchnest lets customers choose their preferred format from the same collection link, maximising conversion.
