There are several elements to focus on when testing replicated emails:
Subject Lines: Test different subject lines to see which one garners the highest open rates. Preheader Text: Ensure that the preheader text complements the subject line and entices recipients to open the email. Content and Layout: Check for any formatting issues across different email clients and devices. Links and CTAs: Verify that all links and calls-to-action are working correctly. Images: Ensure that images load properly and have appropriate alt text.
