A call to action (CTA) is a prompt in an email that encourages recipients to take a specific action, such as clicking a button, visiting a landing page, or making a purchase. CTAs are critical conversion elements that guide subscribers from reading your message to completing your desired goal, whether that is downloading a resource, signing up for a trial, or contacting sales.
CTAs directly impact your email conversion rates and campaign ROI. Without a clear CTA, subscribers may read your email but take no action, wasting your marketing effort. A well-crafted CTA removes friction from the decision-making process and tells readers exactly what to do next. Studies show that emails with a single, focused CTA can increase clicks by 371% and sales by 1617% compared to emails with multiple competing actions.
Effective CTAs combine compelling copy with strategic placement and visual design. The CTA button or link is positioned where readers naturally focus after consuming your email content. Action-oriented verbs create urgency and clarity, while contrasting colors make the CTA stand out. When a subscriber clicks, they are directed to a dedicated landing page optimized to complete the conversion.
Buttons typically outperform text links because they are more visually prominent and clearly indicate clickability. However, text links work well as secondary CTAs or in text-heavy emails. Many successful emails use a button for the primary CTA and text links for secondary actions.
Focus on one primary CTA per email. Multiple CTAs competing for attention can reduce click rates by up to 90%. If you must include secondary actions, make them visually subordinate to your main CTA and limit total CTAs to 2-3.
There is no universal best color - what matters is contrast with your email design. The CTA should be the most visually prominent element. Test colors that align with your brand while standing out from the background. Orange, green, and red often perform well, but your results will depend on your specific design and audience.
Place your primary CTA above the fold so readers see it without scrolling. For longer emails, repeat the CTA at the end after you have made your case. Eye-tracking studies show readers often look at the center and left side of emails, making these prime CTA positions.
