Put Your Reviews in Your Email Signature
Short answer: add one line under your name — star rating, review count, and a link to your review page. It takes four minutes and it works on every email you'll send for the rest of the year.
Every quote, every reply, every "here's the invoice" is going to someone who is quietly assessing you. Your signature is the only piece of marketing that rides along with all of it, and most signatures contain nothing but a phone number and a legal disclaimer nobody reads.
The Minimal Version

⭐ 4.9 from 214 reviews → getkudo.co/yilmazdental
That's it. One line, one link, no images.
Why the Plain Text Version Wins
Images get blocked. Many email clients block remote images by default. A signature that depends on a star-rating graphic shows up as an empty box.
Images don't get clicked as reliably as a short piece of text that says exactly what's behind it.
Big signature graphics look like marketing. A single line reads like a fact.
It survives forwarding. Your email gets forwarded internally to the person who actually decides. Text survives that; a fancy HTML block often doesn't.
If you do want a logo, keep it small and always pair it with text.
Wording That Performs
The pattern is: rating + volume + destination.
- "⭐ 4.9 · 214 Google reviews → see them here"
- "Rated 4.9/5 by 214 customers · getkudo.co/name"
- "⭐⭐⭐⭐⭐ What our clients say"
- For low review counts: skip the number. "⭐ See what our clients say → link"
Include the count when it's impressive. "4.9 from 214 reviews" is much stronger than "4.9 stars", which could be four people.
Skip the count when it isn't. "5.0 from 3 reviews" invites the wrong thought. Just link to the page.
Don't fake precision. If it changes, use a page that updates itself rather than hardcoding a number you'll forget to change. A signature claiming 4.9 while your profile shows 4.3 is worse than saying nothing.
Where Else the Same Line Belongs
Once you've written it, paste it everywhere signatures live:
- Every team member's email. One inconsistent signature undoes the effect.
- Quotes, proposals and estimates — in the footer, next to the price.
- Invoices. People pay more calmly when the business looks established.
- Booking confirmations and appointment reminders.
- Out-of-office replies. "Back Monday — meanwhile, here's what our clients say."
- WhatsApp Business profile.
- Your Instagram bio.
The point isn't any one placement. It's that the same fact appears everywhere someone encounters you, without you having to remember to mention it.
Setting It Up
Gmail: Settings → See all settings → General → Signature. Create one, set it as the default for new mail and replies. Most people forget replies, which is where most of the volume is.
Outlook: File → Options → Mail → Signatures. Same — set for both new messages and replies.
Apple Mail: Mail → Settings → Signatures. Uncheck "Always match my default message font" if it strips your formatting.
Team-wide: Google Workspace admins can enforce a signature template across the domain. Do this rather than asking everyone individually; you'll never get full compliance otherwise.
Track Whether It Works
Add a UTM parameter to the link so you can see the traffic:
"getkudo.co/yourname?utm_source=email&utm_medium=signature"
Check monthly. If nobody's clicking, the line is probably buried under three other lines — cut everything else.
Common Mistakes
A signature with eleven lines. Name, title, company, address, phone, mobile, fax, website, four social icons, a quote, and a confidentiality notice. Nothing in that gets read. Cut to four lines and one link.
Hardcoding a rating you'll never update. In two years it will be wrong and someone will notice.
Linking to Google Maps. It's a worse experience than a page you designed, and it puts your competitors on screen.
No signature on replies. Most of your email volume is replies.
Different signatures across the team. Standardise it.
Frequently Asked Questions
Is it unprofessional to put reviews in a signature?
Not if it's one line of fact. It becomes unprofessional at three lines of self-praise and a badge graphic.
What if my rating drops?
Link to a page that reflects reality rather than stating a fixed number, and it takes care of itself.
Should I link to Google or my own review page?
Your own page: it shows multiple platforms, loads fast, and doesn't display competitors. Link to Google when the goal is specifically to collect new Google reviews.
Does this work for B2B?
Yes, arguably better. B2B buyers forward emails internally, so your proof travels to people you never emailed.
How do I know it's working?
UTM parameters, and the more direct signal: people mentioning your reviews on calls without you bringing them up.
One Link, Everywhere You Already Are
Kudo gives you a review page that stays current on its own — Google reviews imported automatically — so the link in your signature is accurate without you touching it.
