Several factors contribute to the clarity of a CTA:
Action-Oriented Language: Use verbs that prompt action, like "Buy Now," "Sign Up," or "Learn More." Visibility: Ensure that the CTA stands out visually. Use buttons, bold text, and contrasting colors. Simplicity: Keep the message straightforward and easy to understand. Relevance: Make sure the CTA aligns with the content of your email and the expectations set by your subject line and preview text.
