A new research paper introduces Foyer, a self-hosted personal inbox agent designed to improve email routing and decision-making. The study proposes a rigorous measurement protocol to establish ground truth for email classification before training, addressing the common issue of systems evaluating themselves. Experiments comparing Foyer against various baselines, including logistic regression and LLMs like Qwen2.5-7B and Gemma 4 26B/31B, indicate that traditional methods like logistic regression achieve high accuracy on core tasks, while LLMs struggle to match this performance, especially with few-shot prompting. The research also highlights that sender relationship context is crucial and best managed in a contact graph rather than through prompt engineering, and emphasizes that accuracy alone is not the sole product metric, with cost-effectiveness and action-oriented thresholds being critical for practical application.
