Email delivery for web apps

Start sending in minutes

Get started in minutes using our SMTP interface or use our simple JSON API to send emails. With over 20 supported libraries, integration is easy for any application.

Get your emails to the inbox

With over 8 years of experience, we deliver 99-100% of emails to the Inbox. We handle reverse dns, IP reputation, feedback loops, bounces and white listing. By sending transactional email only and using shared IPs with a history of great reputation, your messages are not throttled by ISPs, resulting in fast delivery every time.

Process incoming email

Receiving email into your application could not get any easier. Generate a unique email address or point a domain at our mx record. Inbound messages are then sent to you via web hook in a neatly organized JSON document.

Full content activity stream and search

Easily view the volume of email you send over time, including detailed bounces and spam complaints. Through a simple and fast search interface you can quickly find the last 45 days of sending or inbound history, including the full content, raw messages source, and bounce reasons. Additionally, you can use our JSON API to search and retrieve past messages or web hooks to notify your application about new events.

Transactional email only

Postmark is built for transactional email only. This provides a clean interface and a focused API meant to send your application’s emails. By sending only transactional email, our success of getting to the inbox is much greater as our overall spam and bounce rates are much lower. Keep in mind, we DO NOT allow email marketing or newsletters to be sent through Postmark.

Open tracking and statistics

Track opens for HTML emails, allowing you to track opens for campaigns (tags) and individual recipients. Statistics include geographic data, email client, platform and even how long your emails were read in seconds. All data is visible via the UI and accessible through our API.
