Add a Customer Testimonial to Your Email Signature and Build Trust on Every Send

Your email signature is seen by dozens of people every day — prospects, partners, collaborators. This generator helps you create a professional signature that includes a rotating or pinned customer testimonial, silently building credibility with every email you send.

What it does

Turn every email into a micro sales moment

A testimonial in your signature isn't pushy — it's social proof at precisely the right moment, when someone is already in conversation with you. It nudges cold prospects and reinforces trust with existing contacts without any extra effort.

Look polished and professional

The generator creates a visually clean, HTML-formatted signature that renders correctly in Gmail, Outlook, and Apple Mail. No design skills needed — just fill in your details and your best quote.

Pairs perfectly with Senja

If you use Senja, you can pull your best testimonials directly into the generator and link your signature to your full Wall of Love page — giving recipients somewhere to go if they want to see more proof.

How it will work

Enter your contact details and branding

Add your name, job title, company, website, and optionally a headshot or logo. Choose a colour scheme that matches your brand or Senja's default purple if you prefer.

Add your testimonial

Paste in a short, punchy customer quote (1-2 sentences works best). Add the customer's name, company, and optionally their photo or company logo for extra credibility.

Copy and install in your email client

The generator produces clean HTML you can paste directly into Gmail, Outlook, or Apple Mail settings. Full installation instructions are included for each major email client.
