There are several key elements to test in an email campaign:
Subject Line: Ensure it is compelling and relevant to your audience. Preheader Text: This should complement the subject line and entice readers to open the email. Content and Copy: Check for clarity, grammar, and relevance. Design and Layout: Ensure the email is visually appealing and displays correctly on various devices. Call to Action (CTA): Make sure the CTA stands out and is easy to find. Links: Verify that all links work properly.
