How to add testimonials to emails

Embed social proof in your email signature, newsletter, or campaign. Whether you use Mailchimp, ConvertKit, Gmail, or Outlook, Vouchnest makes it easy to share testimonials without cluttering your layout.

The universal snippet

This works inside any email builder that supports custom HTML. Replace YOUR_SPACE_IDwith your space ID from your Vouchnest dashboard and paste the snippet where you want the wall to appear.

HTML snippet

<script src="https://cdn.vouchnest.com/widget.js" data-space-id="YOUR_SPACE_ID" async></script>
<div id="vouchnest-wall"></div>

Fallback ready

Most email clients block JavaScript. Use a linked image or plain text link alongside the snippet for maximum compatibility.

Self-updating

Approve a testimonial in your dashboard — it appears everywhere you've embedded the wall. No manual resends needed.

Responsive

The hosted wall link works on any device. Email recipients see a clean, mobile-friendly page when they click through.

No code? Use the hosted wall page

Every Vouchnest space gets a hosted wall page at vouchnest.com/wall/your-space-slug. Link to it from your email signature or campaign body. No HTML embedding needed — just paste the URL. It’s fully public, updates automatically, and works as a click-through destination.

Frequently asked questions

Can I embed video testimonial in email?+

Most email clients do not support embedded video playback. Instead, include a static image thumbnail linked to your Vouchnest hosted wall where the video plays. This gives recipients a visual preview while keeping the email lightweight.

Will images show up in the testimonial wall inside email?+

Images may be blocked by default in many email clients. Use the hosted wall link as a fallback — recipients click through to see the full testimonial wall with all images and videos rendered natively.

Will embedding the snippet trigger spam filters?+

The Vouchnest snippet alone won't trigger spam filters. However, avoid excessive JavaScript or external script calls. For best deliverability, stick to plain text links or linked images pointing to your hosted wall page.

Can I track clicks on testimonial links in email?+

Yes. Use your email platform's built-in link tracking (Mailchimp, ConvertKit, etc.) on the hosted wall URL. You can also use UTM parameters on the link to measure traffic in Google Analytics.

What is the best format for testimonials in email?+

A linked text snippet or a branded button pointing to your hosted wall page works best. Email HTML with JavaScript is unreliable — the hosted wall URL is the most universal and deliverability-friendly format.
