A/B testing involves sending two variations of an email to a small segment of your list to see which performs better. Key elements to test include:
Subject Lines: Test different subject lines to see which one gets more opens. Call-to-Action (CTA): Experiment with different CTAs to see which one drives more clicks. Email Design: Test different layouts and designs to see which one is more engaging.
Once you identify the winning version, send it to the rest of your list for optimal results.
