Get the outbound deliverability rollup for a domain — sent, delivered, soft/hard bounce counts, delivery rate, bounce rate, and health status (good/warning/poor). Mirrors the stats cards on the domain detail page.
AI agents call get_domain_deliverability to retrieve information from TrekMail MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of email domain statistics and metrics. It returns aggregated data about email delivery performance without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal — an agent could only retrieve information about a domain's email statistics, which does not compromise data integrity or trigger external actions.
From the tool's definition Tool retrieves and queries deliverability metrics (sent, delivered, bounce counts, delivery rate, bounce rate, health status) with no modification capability — 'Get the outbound deliverability rollup' and 'Mirrors the stats cards' indicate data retrieval only.
