Halon for email marketers

Large scale email marketers need to be sure their emails are delivered without delay and in a secure manner. The Halon MTA provides exceptional flexible integration capabilities, outstanding reliability and performance, whilst being agile to support your scalability and growth.

Just the way you like it

Fully scriptable, customizable and extensible, but lean and compact at the same time. A lack of flexibility in the MTA can lead to compromises and complexity, resulting in high maintenance costs and risks. The Halon MTA can be tailored to specific needs with virtually unlimited customization. That's one of the many reasons we are the developers' choice. 

Security at its core

Security is in our DNA. The Halon MTA supports all the latest encryption and authentication standards whilst also allowing you to quickly implement and integrate existing and emerging standards for email authenticity such as DKIM signing, DMARC verification and ARC.


Why is Halon for you?

Powerful performance, with security at its core. Large-scale senders of transactional or marketing email need an MTA that enables them to scale quickly and send emails securely. 

The Halon MTA gives Email Marketers full control, with unrivalled security features, deliverability automation and more.

Customer cases



One.com is one of Europe’s leading and most innovative web hosting providers with over one million customers in 149 countries. Due to their high-growth rate, One.com was looking for a platform that would reduce operating costs and could scale better over time.



Maskatel is an independent telecommunications company in Canada currently running approximately 20,000 mailboxes. In 2013, Maskatel was searching for a security solution that would improve their customer experience and reduce their inbound support calls. 


We researched and evaluated many email security and delivery platforms against our requirements. We finally settled on the Halon email platform based on price performance, ease of use, flexibility, multi-tenancy support with security and its ability to scale on demand
