- No session replay or heatmap tools.
- No marketing automation vendors beyond the Postmark email processor noted above.
Changes to this list
A new processor is added here at the point of integration. A change to an existing processor's role is reflected within 7 days. We do not currently remove historic rows when a processor relationship ends; superseded relationships are marked with a date range so the history remains legible.
