What makes PowerMTA special?
Clear focus: What sets PowerMTA apart from other solutions is the clear focus on email delivery: “doing one thing and doing it well”. This makes it the perfect fit for a best-of-breed solution with third-party CRM software, campaign front-ends or custom email applications.
Flexible hosting: PowerMTA is delivered as software, and not as a hardware appliance, like many other vendors. Both Windows and Linux versions are available. This means that you use your preferred hosting platform, from dedicated on-premise to the cloud or anything in between.
Industry standard: PowerMTA is used by more than 70% of Email Service Providers to power their email delivery infrastructure. Many smaller senders, marketing agencies and enterprises also use PowerMTA to make their email delivery reliable, secure and fast.

Our PowerMTA integration components
Postmastery has developed software components that allow easy integration with email applications. We have components for Interspire, Ongage, and for custom web applications.

Because it uses common interface standards HTTP, REST, and JSON it works with any web framework or programming language.
