2024 has been nothing short of remarkable for Halon. As we look back, one theme stands out: creating tangible value for our customers. Whether it was accelerating business growth, speeding time-to-market, or improving customer experiences, each company that adopted our solutions saw a significant impact, enough to justify integrating Halon deeply into their workflows.

Our customer-first mindset translated into an extraordinary NPS score of 75, an endorsement that grows year over year. From Netcore to Zendesk to Constant Contact and Mailkit, customer stories confirm the value we bring. And we couldn’t be prouder to celebrate a decade-long partnership with one.com - ten years of growth and counting! Every customer story reinforced the same message: when email infrastructure works seamlessly, businesses flourish.

Last year, we secured a strategic investment from Intera Partners, an invaluable catalyst for our next phase of global growth. While the partnership began last year, its true impact will shine in 2025 and beyond. With Intera’s support, we’re positioned to expand our presence globally, bringing deeper innovation and world-class support to our customers. It’s about far more than capital; it’s the momentum we need to expand our capabilities and deliver even greater value in the years ahead.

Building the foundations: 2024's product evolution

Behind every success story stood our innovation-first approach. Even as the email industry confronted new threats, like echospoofing and quishing, and mailbox providers continued to tighten their sender guidelines, Halon’s Engage and Protect products kept innovating at a rapid pace. We introduced features that directly addressed the most pressing needs of email teams: better control, deeper insights, and smarter solutions.

Halon Engage

• Version 11 brought customizable dashboards and historical logging, slashing time-to-diagnose for deliverability challenges.
• Version 12 delivered Sender Shield, keeping customers compliant and protected in the face of evolving mailbox-provider rules.
• Version 13 introduced advanced traffic segmentation with TenantID, boosting precision in large-scale sending environments.
• Version 14 unveiled Delivery Orchestrator for next-level traffic management, plus our AI-powered bounce classification, a sneak peek of how intelligence will shape email delivery in the coming years.

Halon Protect

• Version 11 enhanced dashboards and historical views, giving teams a holistic lens on email performance and security.
• Version 12 focussed on optimizing DNS resolution layer, trimming valuable seconds off of DNS checks, and speeding up email delivery in the process.
• Version 13 launched an industry-first TLS-RPT report generator introducing advanced DLP features to safeguard sensitive information on dashboards.
• Version 14 embraced cloud-native scalability with automated horizontal auto-scaling on Kubernetes, blending seamlessly with Delivery Orchestrator and AI-based bounce classification.

Our product roadmap in 2024 was about keeping one step ahead of the industry’s rapid changes, ensuring our customers could stay agile, secure, and fully in control.

What’s in store for this year?

Imagine Halon Engage and Protect becoming even more intelligent, powering email operations with actionable insights. While mailbox providers often react in real-time, deliverability teams frequently find themselves behind the curve, stuck in a reactive loop across thousands of domains and millions of recipients. Our upcoming “Delivery Guru” will address these bottlenecks by proactively monitoring, alerting, and recommending optimizations at scale. From domain warm-ups to daily traffic changes, teams can finally move from “firefighting” to “forward-planning”.

On the Halon Protect side, we’re honing “Policy Magic”, an intelligent solution to transform the way email and anti-spam teams craft and maintain policies. By embedding AI and robust ML models, we’ll learn “what’s normal” in your infrastructure and swiftly highlight anomalies, whether that’s unusual sending patterns or inbound spear phishing attempts. Expect more building-block-style features for infrastructure providers, with advanced DLP capabilities to prevent accidental data leaks, or any other use case you can imagine.

Underpinning all of this is “Code Companion”, our upcoming co-pilot designed to streamline how developers and operators craft custom workflows using HSL. It’s about giving you the power to flex, adapt, and innovate, at lightning speed, without having to wrangle complexity.

In short, 2025 is about empowering email teams to anticipate and solve problems before they escalate - unlocking new growth opportunities, reducing costs, and saving time. 

2024 taught us that bold thinking and an unwavering commitment to customer success can keep you ahead of even the fastest-moving changes. We’re proud of the product strides we’ve made, the customer stories we’ve powered, and the global foundations we’ve laid.

Now, we’re eager to carry that momentum into 2025 - an even more hopeful year for email infrastructure. Together, we’ll continue shaping the future of email, raising the bar for deliverability, security, and performance. Thank you for being part of this journey, and here’s to a thriving 2025 ahead!
