Every email you send is a touchpoint with a customer or prospect. Adding a one-click review button turns routine correspondence into a passive review-generation channel — no follow-up required.
Business owners who add a review CTA to their signature typically see 10–20% of active email contacts convert to reviewers within the first 90 days.

Email signature FAQ
How do I add a review link to my email signature?
Paste your Google review URL into the 'Review link' field in the builder. The tool turns it into a tappable CTA button inside your signature, so anyone who reads your email can leave a review in one click. If you don't have a direct link yet, generate one first with our free Google review link tool, then drop it in here.
Does an HTML email signature work in both Gmail and Outlook?
Yes. The signature is built with inline-styled HTML that renders in Gmail, Outlook (desktop and web), Apple Mail, and most webmail clients. Use the 'Copy for Gmail' button to paste rich content straight into Gmail's signature editor, or 'Copy HTML' to paste the raw source into Outlook and other clients.
How do I paste an HTML signature into Gmail?
Click 'Copy for Gmail' in the builder, then open Gmail → Settings (gear icon) → See all settings → General → Signature. Create or edit a signature, click into the box, and paste with Ctrl+V (Cmd+V on Mac). The formatting, button, and links carry over. Scroll down and click 'Save Changes' to apply it.
Will my logo and images show up in the signature?
Images display as long as they're hosted at a public URL — the signature references them by link rather than embedding the file. Avoid pasting images from your computer, since those won't load for recipients. The review CTA in this builder is a styled HTML button (not an image), so it always renders even when a recipient's client blocks images by default.
What are the best practices for getting more reviews from an email signature?
Keep the CTA short and specific — 'Leave us a review' or 'Rate your experience' outperforms generic wording. Link directly to your Google review page so customers skip the search step, use a button rather than a plain text link so it stands out, and add it to every team member's signature so every email becomes a quiet review request. Pair it with a real ask after a great interaction for the highest conversion.
