How to Test Email Performance with Large Image Files?
Before sending out your email campaign, it’s crucial to test its performance: 1. Use A/B Testing: Send different versions of your email to see which performs better. 2. Pre-send Testing Tools: Use tools like [Litmus]() or [Email on Acid]() to test how your email renders on various devices and email clients. 3. Monitor Metrics: Keep an eye on open rates, click-through rates, and conversion rates to gauge the impact of your images.
