Postmark Node.js Library

The `postmark` package is the official Node.js client library for interacting with the Postmark HTTP API, facilitating robust email sending and parsing capabilities within Node.js applications. It provides high delivery rates, comprehensive bounce and spam processing, and detailed email statistics. The current stable version is 4.0.7, which has recently updated its underlying HTTP client (`axios`). The library sees frequent patch releases to keep dependencies current and make minor model adjustments, with major version increments typically aligned with Node.js End-of-Life (EOL) cycles. Its key differentiators include being an official, actively maintained client with full support for Postmark's REST API, including features for both sending transactional emails and parsing incoming emails.
