View click heatmaps on published newsletters

The click heatmap lets you visualize reader engagement by overlaying click data directly on your published newsletter. Each link is color-coded based on how many clicks it received, making it easy to spot which content resonated most with your audience.

How to view the click heatmap

1. Open a published newsletter issue.
2. Find the Show/Hide toggle in the preview header.
3. Toggle it on to overlay the heatmap on your newsletter.
4. Review the color-coded links to see which received the most clicks.
5. Toggle it off to return to the standard preview.

Understanding the heatmap

Links are colored by click volume, so you can quickly identify:

• High-performing content that drew the most engagement
• Underperforming links that may need better placement or messaging
• Reader behavior patterns across different sections of your newsletter
