Use when processing incoming emails with Postmark inbound webhooks — building reply-by-email, email-to-ticket, document extraction, or any workflow that receives and parses email.
Use when sending transactional or broadcast emails through Postmark — single sends, batch (up to 500), bulk, or template-based emails with support for attachments, tracking, and message streams.
Use when creating, managing, or sending with Postmark server-side email templates — Handlebars syntax, layout inheritance, template validation, and cross-server pushing.
Use when setting up Postmark webhooks for tracking email delivery, bounces, opens, clicks, spam complaints, or subscription changes — includes webhook configuration, payload handling, and security.

| Token | Header | Scope |
|---|---|---|
| Server Token | X-Postmark-Server-Token | Sending emails, templates, bounces, webhooks, message streams |
| Account Token | X-Postmark-Account-Token | Managing servers, domains, sender signatures |
Get your Server API Token from Postmark Servers.
Detect the project language and install the appropriate SDK:
| File | Language | Install Command |
|---|---|---|
package.json | Node.js / TypeScript | npm install postmark |
requirements.txt / pyproject.toml | Python | pip install postmarker |
Gemfile | Ruby | gem install postmark |
composer.json | PHP | composer require wildbit/postmark-php |
*.csproj / *.sln | .NET | dotnet add package Postmark |
Postmark separates email by intent into Message Streams:
| Stream | Value | Purpose |
|---|---|---|
| Transactional | outbound | 1:1 triggered emails (welcome, password reset, receipts) — default |
| Broadcast | broadcast | Marketing, newsletters, announcements |
Never mix transactional and broadcast email in the same stream — it damages deliverability.
