Why PMTA as email delivery software?
Clear focus: What sets PMTA apart from other alternatives is its clear focus on email delivery. "Doing one thing and doing it well". It is the perfect fit for a best-of-breed solution with third-party CRM software, campaign front-ends or custom email applications.
Easy to run and manage: PMTA is delivered as a simple executable for both Linux and Windows. It runs on any hosting platform, from dedicated hardware to cloud based VMs. A web-based interface can be used for configuration and monitoring.
Industry standard: PMTA is used by more than 70% of Email Service Providers (ESPs) to power their email delivery infrastructure. Many smaller senders, marketing agencies and enterprises also use PMTA to make their email delivery reliable, secure and fast.
Postmastery's consulting services
Installation: After acquiring a PowerMTA licence, the software needs to be properly installed and configured. With a manual of over 300 pages describing over 200 configuration parameters, you feel overwhelmed. Our PMTA set-up service builds upon more than a decade of expertise. We translate your needs and requirements into a working configuration that incorporates much learning and best practices.
Assessment: You may have been using PowerMTA for a while but are wondering if you are using its full potential. Throughput may be limited, the delivery times may be long, or there may be many temporary errors and retries. You also want to be sure that the settings for recipient domains are compliant with provider policies and common best practices, and that the configuration is in good shape. In this case a PMTA assessment is advisable.
Monitoring: Sustained deliverability requires constant attention. Postmastery's Delivery Analytics can proactively monitor the entire PMTA infrastructure and logs by automatically flagging non-compliances. Postmastery's PMTA consulting service also offers a proactive 'expert view' on configuration, IP reputation, email delivery.
Looking for expert level PowerMTA knowledge?
Postmastery has developed software components that allow easy integration with email applications. We have components for Interspire, Ongage, and for custom web applications. Our components leverage PMTA's bounce and complaint processing and use standard HTTP APIs to pass bounce and complaint data back to the application.
PowerMTA accounting webhook: Postmastery’s accounting webhook passes accounting data to custom web applications in real-time. Because it uses common interface standards like HTTP, REST and JSON, it works with any web framework or programming language. It can be used to collect bounce and complaint information without the need to process bounce emails or complaint reports.
Webhook for list-unsubscribe: Postmastery's webhook for List-Unsubscribe is run by PMTA when it receives unsubscribe emails. It extracts parameters from the receiving address and calls a http link with these parameters. Thus the application only needs to support (one-click) unsubscribes via http.
If you would like to send from public IPs on a different/remote host without the need to install another MTA, then Postmastery MTA proxy can help. The solution is optimised for SMTP traffic with multiple source IPs and many connections. It also provides a proxifier to intercept connections from MTAs, which typically don’t have built-in support for proxies.
