Definition
CTA button copy is the most high-stakes text in your email. It is the final nudge that turns a reader into a clicker. Effective CTA copy tells subscribers exactly what they will get and uses action-oriented language that creates anticipation.
Best Practices
- Start with a verb: "Shop," "Download," "Get," "Start," "Claim," "Learn"
- Be specific: "Get 20% Off" outperforms "Shop Now"; "Download the Free Guide" outperforms "Learn More"
- Create urgency: "Claim Your Seat — Only 3 Left" or "Get Offer Before It Expires"
- Use first person: "Start My Free Trial" outperforms "Start Your Free Trial"
- Keep it short: 2-5 words ideally; never more than 8
- Avoid generic: "Submit," "Click Here," and "Go" should never be used
Testing
A/B test CTA copy as often as subject lines. The difference between "Shop Now" and "Shop the Sale" can be 30% or more in click rate. Test one variable at a time — copy, then colour, then size, then placement.
