How to measure the effectiveness of longer emails?
Measuring the effectiveness of longer emails involves tracking various metrics. Open rates and click-through rates (CTR) are basic indicators of engagement, but for longer emails, you might also want to track scroll depth and time spent reading the email. These metrics can provide insights into whether your audience is reading the entire email or losing interest partway through. A/B testing different lengths and formats can also help you determine what works best for your audience.
