    note: >-
      The Webhooks CRUD operations this skill describes are documented in
      Postmark's API reference but are absent from the OpenAPI captured in
      openapi/, so no operationIds are listed. See mcp/postmark-tool-crosswalk.yml.

      Use when asking about email deliverability, compliance (CAN-SPAM, GDPR,
      CASL), transactional email design patterns, list management, testing
      safely, or general email best practices — provider-agnostic knowledge with
      Postmark-specific guidance.
    references:
      - compliance.md
      - deliverability.md
      - list-management.md
      - sending-reliability.md
      - testing.md

skill_count: 5
coverage_note: >-
  The provider's skills cover sending, inbound, templates and webhooks. They do
  NOT cover the account-token surface (domains, sender signatures, server
  management), suppressions, stats, or the Bulk API shipped 2026-03-05 — the
  skills were published 2026-02-27, before it. Compare with
  mcp/postmark-tool-crosswalk.yml, which shows the MCP server has the inverse
  gap: it covers suppressions and stats but has no inbound coverage at all.
