Heatmaps show when threads arrive and when agents respond, broken down by hour of day (UTC) and day of week. Use them to spot coverage gaps and plan staffing.

Available heatmaps

​
How each cell is calculated

Each cell shows the count for that hour-of-day and day-of-week combination, summed across every week in the selected period. A 4-week period means each cell aggregates up to 4 days’ worth of data. Hour buckets run 0-23 UTC. Thread counts exclude threads from deleted or spam customers and threads created by Plain users. Message counts cover outbound agent messages only; auto-replies and AI-generated messages are not included.

How to read it

Darker cells mean more activity. Hover over any cell to see the exact count.

How to use it

Set the period to at least 4 weeks to get a reliable pattern. Comparing the Threads created heatmap against Messages sent (from a team member’s page) shows when threads are arriving but no agent is responding.
