Track engagement over time for any audience segment

You can see how several saved segments — or your entire subscriber base — engage over time. Compare multiple segments side by side on one chart to quickly understand which audiences drive stronger engagement. Chart open rate, click rate, click-to-open rate, and bounce rate day by day, with your whole-audience baseline drawn as a dashed line to read each segment against.

How to view segment engagement over time

1. Open your analytics — see Letterhead Reporting.
2. Select one or more saved audience segments from the segment picker, or choose your whole audience.
3. Select a date range for the chart.
4. Review the engagement metrics plotted day by day:
   • Open rate — the percentage of emails opened
   • Clickthrough rate — the percentage of emails with at least one click
   • Click-to-open rate — the percentage of opens that led to a click
   • Bounce rate — the percentage of emails that bounced
5. Compare each segment’s performance against the whole-audience baseline and against each other. A total for the whole period appears beside each segment.

Tracking engagement by sign-up source

Letterhead automatically captures where each reader signed up. Create a segment filtered by sign-up source to answer questions like “How do readers from this partner engage compared to my overall audience?” No additional setup is required — build the segment and view its engagement chart.

Filter and export

• Filter by newsletter — view trends across all your newsletters at once, or narrow to subscribers of a single newsletter.
• Download as CSV — export the full time series to dig deeper in your own tools.

This helps you spot whether a segment’s engagement is climbing or slipping, so you can adjust your content strategy accordingly.
