Large files can skew your email analytics in several ways: 1. Open Rates: Large files can deter users from opening your emails, reducing your open rates. 2. Click-Through Rates: If your email takes too long to load, users may not wait to click through your content. 3. Bounce Rates: Emails with large files are more likely to bounce back, affecting your bounce rate statistics. 4. Engagement Metrics: User engagement can drop if your email takes too long to load, resulting in lower interaction with your content.
