Common Setup

Authentication

Postmark uses two types of API tokens:

TokenHeaderScope
Server TokenX-Postmark-Server-TokenSending emails, templates, bounces, webhooks, message streams
Account TokenX-Postmark-Account-TokenManaging servers, domains, sender signatures

Get your Server API Token from Postmark Servers.

SDK Installation

Detect the project language and install the appropriate SDK:

FileLanguageInstall Command
package.jsonNode.js / TypeScriptnpm install postmark
requirements.txt / pyproject.tomlPythonpip install postmarker
GemfileRubygem install postmark
composer.jsonPHPcomposer require wildbit/postmark-php
*.csproj / *.sln.NETdotnet add package Postmark

Message Streams

Postmark separates email by intent into Message Streams:

StreamValuePurpose
Transactionaloutbound1:1 triggered emails (welcome, password reset, receipts) — default
BroadcastbroadcastMarketing, newsletters, announcements

Never mix transactional and broadcast email in the same stream — it damages deliverability.
