5 Email Templates to Ask Customers for Testimonials

The hardest part of testimonials isn't displaying them — it's getting customers to write them. Here are 5 proven email templates you can copy and send today.

When to Ask

Timing matters more than the words you use. Ask at these moments:

• Right after a win — they just achieved a result with your product
• After positive support interaction — they thanked you? Ask for a testimonial
• At a milestone — 30 days, 100th order, 1-year anniversary
• After a referral — if they referred someone, they clearly like you

Template 1: The Simple Ask

Best for: SaaS products, after a customer reaches a milestone.

Subject: Quick favor? (30 seconds)

Hi [Name],

I noticed you've been using [Product] for [X weeks/months]
and it looks like things are going well.

Would you mind leaving a quick testimonial? It takes
about 30 seconds:

[Your TrustWall collection link]

Just a sentence or two about your experience is perfect.
No pressure at all.

Thanks,
[Your name]

Template 2: After Positive Feedback

Best for: When a customer sends you a compliment via email or chat.

Subject: Re: [Original subject]

That's great to hear, [Name]! Really made my day.

Would you mind sharing that as a testimonial?
I have a quick form here: [Your TrustWall collection link]

It would really help other people discover [Product].
Totally optional, of course.

[Your name]

Template 3: The Specific Ask

Best for: Getting detailed testimonials that actually help convert.

Subject: Could you help future customers?

Hi [Name],

I'm collecting feedback from customers and would love
to include yours. If you have 60 seconds, could you
answer one of these in a testimonial?

- What problem did [Product] solve for you?
- What would you tell someone considering [Product]?
- What surprised you most about using [Product]?

Here's the link: [Your TrustWall collection link]

Thanks so much,
[Your name]

Template 4: The Follow-Up

Best for: A gentle nudge if they didn't respond to the first ask.

Subject: Re: Quick favor?

Hi [Name],

Just a friendly bump on this — totally understand
if you're busy. Even one sentence would be a huge help:

No worries either way. Thanks for being a customer!

[Your name]

Template 5: The Results-Based Ask

Best for: When you have data showing the customer got results.

Subject: Your results with [Product]

Hi [Name],

I was looking at your account and noticed some great
numbers — [specific metric, e.g., "your page views
are up 40% since adding the widget"].

Would you be open to sharing a quick testimonial
about your experience?

I can keep it anonymous if you prefer.

Best,
[Your name]

Tips for Higher Response Rates

1. Keep the email short — under 100 words
2. Make the link prominent — don't bury it in a paragraph
3. Lower the bar — "even one sentence helps"
4. Follow up once — but only once. Don't spam.
5. Use their first name — personal emails get 2x the response rate
6. Send from a real person — not "[email protected]"

Automate the Process

With TrustWall, you get a unique collection link for each project. Send it via email, embed it in your app's success page, or add it to your post-purchase flow. When a customer submits a testimonial, you get an email notification and can approve it with one click.
