MailerQ is built to deliver large amounts of email. Our solution enables you to manage a powerful on-premise SMTP server. Our easy-to-use Management Console provides real-time insights into all traffic going through MailerQ and enables you to control an extensive set of deliverability settings on the fly. With MailerQ messages never have to touch a disk, so you can say goodbye to your expensive hardware and start delivering with higher performance using low-cost servers.
MailerQ is designed with a strong focus on performance. Due to message queueing in memory and a multi-threaded non-blocking architecture, a single MailerQ instance can easily handle thousands of messages per second.
Five different injection methods, plugin support, REST API, and use of open source components like RabbitMQ and MySQL/PostgreSQL make MailerQ a highly flexible email sending solution.
MailerQ comes packed with functionality necessary for every serious sender. Working together with our customers and industry leaders allow us to continuously bring out the latest and most relevant improvements.
MailerQ previously published an article on this website in which we compared the features and the speed of MailerQ and a competing product, PowerMTA. The comparison was made using an unauthorized installation of a test version of PowerMTA and an unauthorized license without consent of Port25, the copyright-holder of the PowerMTA software. The conclusions of this test were therefore unreliable, not verifiable, and for these reasons false and misleading. This was wrong. We have removed the comparison page from our website and apologize to Port25 and anyone who reviewed the comparison page on our website.
