A good CTA is clear, concise, and action-oriented. Here are key elements to consider: - Actionable Language: Use verbs that encourage actions like "Buy Now," "Learn More," or "Subscribe." - Visibility: Make sure the CTA stands out through color, size, and placement within the email. - Value Proposition: Clearly state what the recipient will gain by clicking the CTA. - Urgency: Phrases like "Limited Time Offer" or "Act Now" can create a sense of urgency.
