Frequently Asked Questions

How is Halon Engage different from a standard MTA?
Halon Engage is a modern email infrastructure powered by intelligence at every layer, which enables Dynamic Email OperationsTM.

Halon Engage gives you full visibility, extendability, and control through a composable architecture, so your email operations stay sharp, resilient, and ahead of the curve.
What’s the cost advantage of Halon Engage compared to open-source solutions?
While open-source appears cheaper initially, hidden expenses add up: infrastructure management, development of new features, support, troubleshooting, and ongoing maintenance. Halon Engage offers predictable costs, lower total cost of ownership, built-in intelligence, and less operational complexity—letting you focus on growth, not management.
