What are the two missing components for creating effective emails?

Creating effective emails hinges on several key components that can impact engagement and conversion rates. The inclusion of a compelling subject line is crucial because it serves as the first impression and the main factor in whether the recipient decides to open the email. A strong subject line should capture the recipient's attention, create curiosity, or convey value succinctly.

The Call to Action (CTA) is another essential element that directs the reader to what they should do next, whether that’s clicking a link, making a purchase, or signing up for more information. An effective CTA is clear, persuasive, and positioned effectively within the email to encourage the recipient to take action.

While other components such as header images, greetings, and signatures contribute to the overall look and personalization of the email, they do not carry the same level of impact on the email's effectiveness as a compelling subject line and a well-defined CTA. These two elements work together to ensure that recipients not only open the email but also engage with it in a meaningful way.
