There are several components of an email that you can test to optimize performance:
Subject Lines: The first thing recipients see. Testing different subject lines can help you find the most compelling ones. Call-to-Action (CTA): Experiment with different CTAs to see which prompts more clicks. Email Copy: Test variations in the body text to see which resonates more with your audience. Images and Videos: Determine whether visual content enhances your email’s effectiveness. Send Times: Test different times and days to find the optimal time for sending emails. Personalization: See if using the recipient's name or other personal touches make a difference.
