MailerQ is a high-performance on-premise Mail Transfer Agent built for sending and controlling large volumes of email. It is built with a strong focus on performance, ease-of-use and insight. The MTA comes packed with an intuitive Management Console and functionality necessary for every serious sender to retain and improve their sender reputation and deliverability rates. That’s why it's increasingly becoming the preferred solution of choice for senders of all kinds, from Email Service Providers and e-commerce platforms to banks and government institutes.

Ease of use

No need to modify configuration files to set up delivery policies. With MailerQ, all deliverability settings - such as delivery rates, IP warmup schedules, message reroutes, IP pools and adaption to server responses - are stored in a relational (SQL) database and can be modified on the fly from an intuitive web-based Management Console. This can be done either for an individual instance or for an entire cluster of MailerQ MTAs, depending on your setup.

With MailerQ, you can easily get insights into your real-time performance and change your settings on-the-fly without having to touch any configuration files.

Insights

A higher volume sender typically wants to know exactly what's going on and integrate that information into local dashboards without being restricted to certain endpoints or limited log data. Besides the Management Console which provides extensive insight into real-time deliveries, MailerQ provides all the result data per delivery in JSON format, including an attempts chain and any other result property you deem relevant. This data can be processed and incorporated within your own monitoring tools like Grafana or an ELK-stack, enabling you to inspect results on any level of granularity including customer, campaign, recipient domain, MTA IP, bulk/transactional and so forth.

With MailerQ, you have access to all data and organized results which you are able to integrate and use with your own systems.

MailerQ insights

Control

Large senders usually want to control their sending configuration from start to finish with the aim to manage the reputation of your own IPs yourself. MailerQ allows you to define exactly how messages should be sent from your IPs or IP pools to certain ISPs, what to do when they complain, how to classify bounces and how to adapt sending behaviour accordingly.

On top of controlling deliveries on the level of IP(-pool) and recipient ISP, with MailerQ you get an extra message selection parameter: tags. With tags, you can organize deliveries into a campaign, customer, type of message, priority - basically anything you would like. You can add as many tags to a message as you want. This allows you to, for example, monitor, pause, fail, or reroute any individual delivery or group of deliveries meeting certain conditions in real time. Accidentally sent out a campaign? Just cancel it in MailerQ! Does some ongoing high-profile delivery need to be rerouted over a different group of IPs? No problem!

With MailerQ, you get superior control over your entire email operations.
