How to Create an Email CTA

A strong call-to-action (CTA) is the most important part of any email campaign. It guides your reader toward the next step, whether that’s making a purchase, downloading a resource, or signing up for an event. However, writing CTA copy and implementing it in an ESP requires attention to both content and technical execution.

In this guide, we’ll walk through the technical steps for creating high-performing CTAs within your ESP.

How to create email CTAs that drive action in your esp

Here is a step-by-step approach to ensure your CTAs get noticed and clicked:

1. Start with a clear goal

Before designing or writing your CTA, define its purpose. Ask yourself:

• What is this email about, and what is the one action you want readers to take?

• Are you selling a product, driving event sign-ups, promoting a download, or guiding readers to a piece of content?

2. Write short, effective CTA copies

Now it’s time to write your copy. When it comes to CTAs, you need a perfect balance between your goal and the tone of your newsletter. Follow these practices to write effective CTA:

• 2–5 words work best for readability and quick comprehension.

• Show what the reader gains by clicking, for example, “Get Your Free Template” is stronger than “Download Template.”

• Make sure the CTA feels natural, whether your brand is professional, playful, or urgent.

• Have two or three variations ready for A/B testing.

• Even subtle tweaks, like “Start Your Free Trial” vs. “Claim Your Free Trial,” can improve engagement.

3. Place and design your CTA

After your copy is finalized, it’s time to add your CTA to your email template. In most ESPs, you can drag-and-drop a prebuilt button, which automatically handles padding, alignment, and mobile responsiveness.

Start with placement. Position your primary CTA near the top of the email, ideally within the first 300–400 pixels so it’s visible without scrolling. For longer emails, repeat the CTA at the bottom to give readers another chance to take action.

Next, focus on design. Add sufficient padding around the button so it stands out from the surrounding text and images. Choose a background color that contrasts with the email’s overall palette, and set a readable text color. These adjustments make your CTA visually distinct, mobile-friendly, and more likely to drive clicks.

4. Link your CTA

A CTA is only effective if it leads readers to the right destination. In your ESP, make sure the button links directly to the intended landing page. Double-check URLs to avoid broken links or misdirects, which can frustrate readers and reduce trust.

Additionally, most ESPs allow you to add UTM codes or integrate with your analytics tools so you can monitor clicks, conversions, and overall performance. This data helps you understand which CTAs are working and informs future testing.

Finally, ensure consistency between your CTA text and the landing page. The promise in your button, whether it’s “Download Your Guide” or “Reserve Your Spot”, should match the content on the destination page.

5. Test and Optimize

Once your CTA is live, testing is key to improving results. Set up A/B tests in your ESP to compare different button text, colors, placement, or surrounding copy. Even small tweaks can make a big difference.

Use analytics to track performance, and if you’re on Mailmodo, take advantage of Click Maps. Click Maps visually show where readers are actually clicking in your email, so you can see which CTAs are performing and which are being overlooked. This insight makes it easier to optimize placement, design, and copy for maximum engagement.

Final thoughts

It’s easy to overthink CTAs and worry that every email has to be perfect to get clicks, but the fastest way to improve and see real results is to start testing. You can start by experimenting with one small change at a time: test different button colors, tweak the wording to highlight a clear benefit, or try placing the CTA in a new spot in your email.

Over time, these small experiments add up, helping you discover what actually drives clicks without the stress of guessing.
