Artificial intelligence is reshaping how marketers work, with advancements in machine learning making it easier for brands to build lasting relationships with customers. But with any new tool comes too much hype, when most teams just want smarter, faster technology that makes a real difference.
That’s where AI decisioning comes in. It adds intelligence and personalization throughout the customer lifecycle, meaning less guesswork and more relevance.
In this guide, we’ll unpack how AI decisioning works, how it stacks up against traditional methods, and how to use it to personalize at scale.

AI decisioning uses reinforcement learning models to understand individual customer behaviors, make decisions, and take action autonomously to achieve a specific goal. Rather than following predefined paths—like “if a customer abandons their cart, send this reminder email after 24 hours”—AI decisioning uses data and agentic AI to personalize the touchpoints that each customer will prefer. What is best for one customer might not be best for another; by understanding individual preferences, marketers have a better chance of increasing customer lifetime value and deepening relationships because AI decisioning constantly learns what’s best for individuals.
Expanding upon existing segmentation practices to AI decisioning creates a competitive advantage for marketers by creating deeper connections between brand and customer. AI decisioning leverages reinforcement learning to analyze vast amounts of data and identify patterns that may not be immediately apparent through traditional methods. While basic segmentation typically relies on predefined criteria—such as demographics or past behaviors—to categorize users into static groups, AI decisioning dynamically learns from customer profiles, constant experimentation, and past interactions for more nuanced and relevant communications at scale. This means that rather than simply targeting a group of users with similar characteristics, AI decisioning can tailor messages and experiences to individual preferences and behaviors at the 1:1 level, creating better experiences that enhance engagement and improve conversion rates.
Additionally, AI decisioning continuously learns from user interactions, refining its models to optimize future decisions. This iterative process helps brands respond to evolving customer needs more effectively and speak to each customer in a way that is more relevant for them. By employing AI decisioning, organizations can create highly personalized experiences that resonate on a deeper level, often leading to higher retention rates and fostering brand loyalty.
Where many journeys are rigid, AI decisioning is responsive and can help personalize at scale. This can make any communication feel far more relevant and aligned with each customer’s journey.
AI decisioning introduces intelligence at key points in a customer journey—deciding when to trigger a message, what path to follow, and which channel to use, and what messages each customer may prefer. Instead of relying on pre-defined logic, it brings flexibility and personalization to campaign flows, making them more responsive to each individual.
Traditional campaigns wait for a specific pre-defined action—like a cart abandonment—before responding. AI decisioning takes a more proactive approach. It can personalize journeys based on specific individual attributes like high likelihood to convert, or early signs of churn. This makes it possible to act before a moment is missed.

Timing of messages can also be refined. Instead of sending messages at the same time for everyone, optimize your messaging to when each person is most likely to open or click or perform any marketer-specific action, and send accordingly.
Since individual customers don’t respond to the same campaign or message the same way, marketers should personalize experiences on a 1:1 basis, based on what’s most likely to lead to a conversion. For example, send messages based on whether they’re more likely to respond to a specific discount, which product recommendation a customer would prefer, or what they are looking for in a re-engagement touchpoint.
This kind of logic reduces the need for guesswork or manually building dozens of journey branches. The system decides the best experience, based on who they are as an individual.
In a Braze webinar on AI decisioning, VP and Head of AI Decisioning, George Khachatryan, summed up a core marketing challenge for those companies relying on predictive AI: “It’s not next best action—it’s next best guess.” While prediction tells you what’s most likely to happen, decisioning makes the best decision based on what’s most likely to happen.

That’s where AI decisioning shifts the model. Instead of uncovering insights, like propensity scores, and empowering marketers to make data based on those scores, AI decisioning agents can test, learn, and actually make every decision in real time—what message to send, which offer to present, when to reach out, and how to follow up. And they do it at scale, at the individual level
Anthony O’Byrne of Kayo Sports shared how his team now automates 60,000 customer journeys every day, using AI decisioning to select from the best experience for each individual based from over 1.2 million potential combinations across timing, content, and channel. “One-to-one personalization became the foundation of our strategy,” he said.
AI decisioning doesn’t require a complete rebuild of your stack or strategy. But it does change what’s possible. Instead of relying on rules that make a prediction to help with relevance, brands can use AI decisioning agents to individualized decisions based on real-time data and desired outcomes—turning the broad idea of personalization into a living, evolving part of the journey, that's actually going to maximize the business KPI that you care about most as a marketer.
The idea of handing control to fully autonomous AI agents can feel like a risk—or worse, a black box. But AI decisioning doesn’t have to mean ceding strategy to AI, but a partnership that can help extend and enhance your use cases. In most cases, it’s about using intelligence that can be embedded into the tools and workflows marketers already use, so decisions can be more personalized without losing sight of the brand or the brief.
Marketers still define the goals, creative and content, the constraints, and the messaging guardrails. AI decisioning simply helps optimize within those boundaries—deciding who to message, when, how, and with what, based on what each customer will prefer at the 1:1 level. That means more time spent on strategy and creative, and less time managing segments, rules, and tests—elevating marketers to be the strategic conductors of the brand.
With AI decisioning, brands can adapt to each customer. Every touchpoint for each individual can be made smarter, from which message gets sent, to when it lands, how it’s delivered, and what happens next. Whether you're looking to reduce churn, increase conversions, or simplify cross-channel campaigns, AI decisioning helps you move beyond to something more relevant, contextual, and scalable.
