 FEATURES

# Powerful, flexible, and built for performance

###### Fine-tune delivery, optimize throughput, and integrate seamlessly with your existing infrastructure for consistent, high-volume performance

![icon\_Complete Control](https://kumomta.com/hubfs/icon_Complete%20Control.svg)

Complete control

Rest easy with the confidence that your investment will remain secure, supported, and within your control.

![icon\_Modern Integration](https://kumomta.com/hubfs/icon_Modern%20Integration.svg)

Modern deployment

Fresh builds for Amazon Linux, Rocky Linux, Ubuntu, and Docker with every update.

![icon\_Modern Deployment](https://kumomta.com/hubfs/icon_Modern%20Deployment.svg)

Modern integration

Your MTA no longer needs to be a black box. KumoMTA supports API injection / management, webhooks, AMQP, Kafka, secure keystores, and data-source-based configuration.

 ![icon\_Safe Performance](https://kumomta.com/hubfs/icon_Safe%20Performance.svg)

Safe performance

KumoMTA is not only capable of relaying millions of messages per hour, it does so without shortcuts like RAM spooling, giving you the speed you need, without the risk of data loss.

 ![icon\_Automated Traffic Shaping](https://kumomta.com/hubfs/icon_Automated%20Traffic%20Shaping.svg)

Automated traffic shaping

Automate your adherence to sending requirements. Thanks to our Lua-first configuration and automation design, you can adjust throttles, pause and resume traffic, and automate IP warmup. KumoMTA even supports rules on a per-tenant basis.

 ![icon\_Cloud Friendly](https://kumomta.com/hubfs/icon_Cloud%20Friendly.svg)

Cloud-friendly

With flexible deployment options, support for containers, clustered throttles, HAProxy and SOCKS5 proxies, KumoMTA was built for those wanting to deploy in the cloud.

 ![icon\_Native Campaign Awareness](https://kumomta.com/hubfs/icon_Native%20Campaign%20Awareness.svg)

Native campaign awareness

KumoMTA is natively aware of both campaigns and tenants, queueing them separately and enabling granular configuration and reporting. Tenants and IPs are de-coupled, providing a superior shared IP experience.

 ![icon\_Automatic MX Rollup](https://kumomta.com/hubfs/icon_Automatic%20MX%20Rollup.svg)

Automatic MX rollup

Say goodbye to fractured configurations and out of date domain mapping tables, KumoMTA automatically identifies MX groups and queues messages together for common throttling and delivery.

 ![icon\_Natively OmniChannel](https://kumomta.com/hubfs/icon_Natively%20OmniChannel.svg)

Natively OmniChannel

KumoMTA not only supports IP pooling natively, but it's also built around channel extensibility, with support for HTTP, Kafka, and AMQP delivery of messages already available with more channels on the way.

**Farhad Hedayatirfad**  
AhaSend

“With features like traffic shaping, automation and management for IP pools, and all the web hooks that they provide, Kumo allows us to write a lot of automation around it. Kumo is now part of AhaSend where I spend the least amount of time: it's just doing what it's supposed to do without any problems. Nice!”
