postmark-email-event-handler

Guides an agent through building and securing an HTTP endpoint that receives Postmark email event webhooks, authenticating deliveries with URL-embedded credentials, validating single-event JSON payloads, routing on RecordType for bounces, spam complaints, opens, clicks, deliveries and subscription changes, and registering the endpoint URL in the Postmark dashboard. Use when creating or repairing a Postmark webhook receiver, adding email engagement or bounce handling to an app, or diagnosing unauthorized, missing, or malformed webhook calls. Not for sending transactional email through the Postmark API, for webhook providers other than Postmark, or for building full inbound mailbox parsing pipelines.
