Best practices for engagement emails

Write your CTA button copy as a first-person action phrase like Start My Trial instead of Submit
Place your primary CTA button above the fold so it is visible before any scrolling begins
Limit the email to a single primary CTA to prevent decision fatigue and protect your click-through rate
Use a high-contrast button color that does not appear anywhere else in the email layout to draw the eye immediately
Add a plain-text hyperlink CTA beneath the button to capture clicks from image-blocking email clients
