The published literature on lead scoring converges on a couple of recurring findings. A B2B feature-importance analysis identified lead source and lead status as the most predictive conversion features (Frontiers in AI, 2025). And a supervised classifier trained on labelled outcomes tends to beat both rule-based heuristics and manual qualification. Yet many B2B teams deploying an LLM for lead prioritisation skip the classifier, skip the labelled outcomes, and instead ask the model to reason its way to a score from contact evidence. Is that defensible, or is it cargo-cult AI?

A practical LLM-based intent-scoring design can do exactly one thing: make a single call to a language model, read a few floating-point scores, and fall back to a keyword heuristic if the model fails. No multi-agent orchestration. No fine-tuned BERT. No LightGBM ensemble. And according to the 2026 literature, an LLM semantic scorer outperforms keyword-based intent detection (Sanjei et al., 2026). The useful insight is that an effective design for sales-email intent scoring can also be one of the simplest — a bounded, schema-constrained LLM step embedded inside an existing dataflow graph, designed to fail open rather than cascade errors downstream. This article unpacks why that design is attractive, what the research actually says, and how to build it without over-engineering.
