Postmark
Postmark is a fast and reliable email delivery service that helps businesses send transactional emails through SMTP and API integration.





What is Postmark
Postmark is an email delivery service that sends your automated emails using modern technology. You can connect it to your website or app through their API or SMTP settings, and it handles the rest. Unlike regular email services, Postmark specializes in transactional emails - the important messages your customers expect right away.
The platform includes tools for tracking email delivery, viewing open rates, and managing bounce notifications. It also offers ready-made email templates that look good on all devices. Postmark separates your automated emails from marketing emails to keep delivery rates high.
The service runs on reliable servers around the world and includes helpful support from email experts. You start with a free account that includes 100 emails monthly, and you can upgrade when you need more.
