Now that you have your goal and audience in mind, you can compose an effective CTA. Your CTA should be concise, clear, and compelling, telling recipients exactly what to do and why they should do it. To make it stand out from the rest of the email, you can use a different color, font, size, or shape. You can also choose between a button, a link, or a text CTA depending on the format and design of your email. When writing a great CTA, consider using action verbs such as "Get", "Claim", "Join", "Learn", or "Refer". Add a benefit or value proposition like "Save 20%", "Get free shipping", "Earn rewards", or "Boost your sales". Create a sense of urgency or scarcity with phrases like "Limited time offer", "Only a few spots left", "Don't miss this chance", or "Act now". Make it more relevant and engaging by using personal pronouns such as "You", "Your", or "Me". You can also use positive or negative emotions like “Excited”, “Curious”, “Frustrated”, or “Worried” to trigger a response. Finally, test different variations of your CTA and measure their performance.
