A/B testing involves sending two variations of your email to a small segment of your audience to determine which version performs better. This method can help you optimize various aspects of your email layout, including:
1. Subject Lines: Test different subject lines to see which one gets more opens. 2. CTAs: Experiment with the placement, color, and wording of your call-to-action buttons. 3. Images and Text: Compare different types of content to see what resonates more with your audience.
