Fastest Delivery to the Inbox

Transactional email must get to the inbox immediately. With over 8 years of experience, we ensure 99-100% of your applications emails are delivered to the Inbox, and fast. You don’t need to worry about managing reverse DNS, IP reputation, feedback loops, bounces and white listing. By focusing on high engagement transactional email, ISPs do not throttle our servers due to bulk and marketing email. Fast and reliable delivery to the Inbox is why people come to Postmark.

Start sending in minutes

You can start sending email in minutes using our SMTP interface or our simple JSON API. You can use one of over 20 supported libraries that make integration easy for any application.

Process incoming email

Postmark makes it easy to integrate Inbound email in your application. You’ll need to generate a unique email address or point a domain at our MX record. Inbound messages are sent to you via web hook in a neatly organized JSON document..

Stats and deep search at your fingertips

Postmark makes it easy for you to view your email volume over time, including detailed information on bounces and spam complaints. You can keep track opens for HTML emails, and keep track of delivery status, opens for campaigns tags and individual recipients. You’ll also see geographic data, email client, platform and even how long your emails were read in seconds. All of this data is visible in your Postmark account and accessible through our API.

Our simple and fast search interface gives you the ability to quickly find the last 45 days of sending or inbound history. This includes the full content of each message, raw messages source data, and bounce information.

You can also use our JSON API to search and retrieve past messages, or use web hooks to notify your application about new events.

Postmark is for transactional email only

Postmark is built for transactional email only, messages generated automatically by an action within your app. Focusing on transactional email ensures your messages get to the inbox.

Keep in mind, we DO NOT allow email marketing or newsletters to be sent through Postmark. This is one of the main reasons that we’re able to consistently get to the Inbox quickly and reliably without being throttled by ISPs.
