LLM Sales-Email Intent Scoring for Inbound Lead Prioritization
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.
