Postmark CLI

Postmark CLI (v1.6.19) is a command-line tool for managing transactional email templates, sending emails, and fetching server information via the Postmark API. Released under MIT, it is maintained by ActiveCampaign with regular updates. Key differentiators include local template preview with hot reloading, smart push that only uploads modified templates, and support for layouts. The CLI integrates easily into CI/CD pipelines and offers interactive prompts via Inquirer. It requires Node.js 14+.
