Analytics and recommendations
Metrics
Delivery, opens, unique opens, clicks, replies, bounces, complaints, unsubscribes, and conversions, per campaign.
Comparisons and insights
Campaign-to-campaign comparisons, segment engagement insights, and plain-language performance summaries suitable for surfacing directly to a non-technical user.
Recommendations
A recommendation describes a hypothesis, a primary metric, a target asset, and a proposed change. Experiment variations (for example, subject-line or send-time A/B tests) are only generated after the user approves the recommendation — an agent should never create an experiment variation without that approval step.
Analytics is not currently exposed as MCP tools; campaign-level preflight data is available via preflight_campaign (see /mcp-tools), and full analytics are available in the ZOLLO web app.
