Additionally, most of the world’s leading Email Service Providers such as MailChimp, Sailthru, Campaigner and countless others trust PowerMTA to send enormous volumes of mission critical email.
Our infrastructure handles core tasks with greater efficiency, intelligence and control than general-purpose open-source MTAs as well as commercial alternatives. PowerMTA can also efficiently handle inbound feedback loops and out of band bounce messages. It also easily integrates with a huge variety of CRM solutions such as Salesforce, Interspire, and Freshworks.
PowerMTA supports IP based rate limiting which is designed to give delivery engineers/admins additional control and allows for throttling the number of attempted recipients on a per-hour, per-minute, and per-second basis separately for each IP address and for each domain/VirtualMTA.
Configuring grouping of domains based on the MX information in DNS is simple and easy in PowerMTA. By automating the MX grouping tasks, PowerMTA has eliminated the need for manual maintenance in keeping track of changes to MX information in DNS.
PowerMTA fully supports the latest standards in delivering email to recipients with internationalized addresses without the need for any additional configuration.
PowerMTA supports the latest versions of email authentication standards DKIM, SPF, DANE. PowerMTA supports the use of TLS 1.2 for delivering email over encrypted channels. PowerMTA will soon support ARC, MTA-STS and TLS 1.3.
We also offer the PowerMTA Management Console, a sleek, web based software solution that allows for the centralized configuration, monitoring and reporting of one or more than one PowerMTA installation. The PowerMTA console allows for enhanced reporting, including IP-based reporting, saved reports, configurable session timeouts and advanced reporting filters (including sets and regular expressions).
PowerMTA has provided Sailthru with a rock solid application that we can push to the limits—and we never have to worry about missing a beat.
PowerMTA is the leading email gateway application (SMTP server) because it allows you to easily adopt the latest authentication specifications for sending high volume emails and to comply with ever-changing authentication policies. Whether you are looking for responsible, high-volume outbound email delivery, or as a core component for your technology stack, PowerMTA just delivers.
PowerMTA provides real-time monitoring of your sender reputation through SMTP responses received from ISPs. This monitoring produces immediate notification of delivery issues and the ability to stop and adjust delivery settings based on SMTP response patterns.
Our extensive tracking and reporting features provide detailed analysis for each VirtualMTA, including customizable bounce categorization and reporting. We are continuously improving our monitoring and reporting tools including: web, XML and JSON-based reporting and delivery monitoring, pre-configured performance reports, advanced bounce analysis and real-time campaign tracking, and a command-line query and reporting tool.
Some MTAs max out at frustratingly low send-rates. When you’ve reached a point where your existing MTA can no longer handle your throughput, instead of adding more servers, PowerMTA helps you deliver greater performance on fewer servers.
