Next Best Channel

Next best channel is a predictive decisioning technique that determines which communication channel is most likely to produce a positive response from a specific customer at a specific moment. Rather than defaulting to a single channel for all customers in a campaign, or selecting channels based on operational convenience, next best channel analysis evaluates each customer's historical engagement patterns, behavioral signals, and real-time context to identify the channel where that individual is most likely to engage with and respond to a given communication.

The practical value is straightforward: the same message delivered through the wrong channel fails even when the content, timing, and offer are right. A customer who rarely opens email but responds immediately to push notifications will not convert on an email campaign regardless of its quality. A customer who has disabled push notifications but reads every SMS they receive needs a different channel selection. Next best channel ensures that the investment made in creating relevant, timely communications is not undermined by delivering them through a channel the customer does not use.

What is Next Best Channel?

Next best channel is a component of next best action decisioning that addresses the question of where to engage a customer rather than what to say or when to say it. It uses machine learning models trained on historical engagement data, including open rates, click rates, conversion rates, and response times by channel and customer segment, to predict which channel will produce the highest engagement probability for each individual customer in a given context.

The inputs to a next best channel model typically include a customer's historical response rates across all available channels, their recent channel activity and session behavior, the type of communication being sent, the time of day and day of week, and any explicit channel preferences the customer has expressed. These inputs are combined to generate a channel propensity score for each available option, and the highest-scoring channel is selected for delivery.

Next best channel is distinct from channel preference management, which simply records and applies the channels a customer has explicitly opted into or expressed a preference for. Next best channel goes further by using behavioral data to infer which channel is most likely to be effective even when explicit preferences have not been expressed, and by adapting channel selection dynamically as each customer's engagement patterns evolve.

How Next Best Channel Works

Next best channel operates within the broader decisioning architecture that governs customer engagement. When a trigger event fires and a communication is determined to be appropriate for a specific customer, the next best channel model evaluates the available delivery options and selects the one most likely to produce engagement.

This evaluation happens in real time, at the moment the communication is ready to be sent, rather than as a static assignment made at campaign setup. A customer whose email engagement has been declining over the past 30 days while their push notification response rate has been rising will have a different channel recommendation today than they would have had three months ago, even if their explicit preferences have not changed.

The model continuously updates as new engagement data arrives. Each interaction, whether the customer opens a message, clicks through, ignores it, or actively dismisses it, feeds back into the channel propensity model, refining the prediction for that customer's next interaction. Over time, the model develops an increasingly accurate picture of each customer's channel preferences and the contexts in which those preferences shift.

Next Best Channel vs Next Best Action

Next best channel and next best action are related but distinct concepts that address different dimensions of the engagement decision.

Next best action determines what to do next for a specific customer: which offer to make, which message to send, whether to act at all, and when. It addresses the content and intent of the engagement. Next best channel determines where to deliver that action: which channel will most effectively reach that customer and produce a response.

In a complete next best experience decisioning system, both questions are answered simultaneously. The action is selected based on what is most relevant for that customer given their current context and lifecycle stage. The channel is selected based on where that customer is most likely to receive and respond to the communication. The two decisions are interdependent: the optimal channel for a retention message may be different from the optimal channel for a promotional offer for the same customer, because the urgency, emotional tone, and customer receptiveness differ between the two interaction types.

Next Best Channel in Omnichannel Engagement

Next best channel becomes particularly important in omnichannel environments where customers are reachable across multiple channels simultaneously. Without channel optimization, omnichannel execution risks becoming omnichannel noise: the same customer receiving the same message across email, push, SMS, and in-app simultaneously because each channel team applied its own default logic.

Effective omnichannel engagement requires not just the ability to reach customers across multiple channels but the intelligence to determine which single channel, or which sequence of channels, is most appropriate for each customer at each moment. Next best channel provides that intelligence, ensuring that omnichannel capability translates into better customer experiences rather than more communication volume.

It also interacts with frequency capping logic: when a customer has reached their communication threshold for a period, next best channel helps determine which remaining channel option, if any, is sufficiently high-value to justify an additional contact within that window.

Next Best Channel with evamX

evamX incorporates next best channel decisioning as a core component of its NBX engine. When a journey or trigger determines that a customer should receive a communication, evamX evaluates that customer's channel propensity scores in real time and selects the delivery channel most likely to produce engagement, drawing on behavioral data from across all channels simultaneously.

Channel propensity models in evamX are updated continuously as new engagement signals arrive, ensuring that channel selection reflects each customer's current engagement patterns rather than historical averages. For customers whose channel preferences are shifting, evamX adapts automatically without requiring manual rule updates.

This integration of next best channel into the broader decisioning layer means that channel selection in evamX is not a separate configuration step but an inherent part of every engagement decision, ensuring that the right message reaches the right customer through the right channel every time.
