Optimisation

How to A/B Test Your Email Signature

Data-driven signature optimisation. What to test, how to measure, and what works best.

What to A/B Test

🔗 CTA Text

"Book a demo" vs "Schedule a call" vs "See pricing". Test which CTA language drives the most clicks.

🖼️ Banner vs No Banner

Do promotional banners increase clicks? Or does a simpler signature perform better?

📸 Photo vs No Photo

Does a headshot increase reply rates? Test with half your team to find out.

🎨 Colour Variations

Brand blue vs brand orange for the CTA. Which colour gets more engagement?

How to Track Results

  1. Add UTM parameters to your signature links: ?utm_source=email&utm_medium=signature&utm_campaign=v1
  2. Change to utm_campaign=v2 for the second variant
  3. Track clicks in Google Analytics → Acquisition → Campaigns
  4. Run each variant for 2–4 weeks to get meaningful data
  5. Compare click-through rates and choose the winner

Testing Framework

  • Week 1–2: Version A (e.g., "Book a demo" with banner)
  • Week 3–4: Version B (e.g., "Schedule a call" without banner)
  • Compare: CTR, reply rates, meeting bookings
  • Winner: Deploy to the full team
