# Postmark

> Send application email through an API or SMTP with delivery visibility.

Postmark is an email delivery service for applications and businesses. Developers connect through its API, SMTP service, or language libraries to send messages such as password resets, receipts, account notifications, and newsletters. Message Streams separate transactional and promotional traffic so teams can organize different types of sending within the same service.

Reusable templates help maintain email content, while message activity, delivery events, and webhooks make it possible to investigate problems and connect email events to application workflows. Inbound email processing can turn received messages into data for an application. Postmark is useful for teams that want managed email infrastructure with tools for integrating, observing, and troubleshooting their sending.
