The Challenge
New York English reactivated its Facebook page as a marketing channel, and prospective students — Mexican professionals weighing executive English coaching — began sending Messenger questions about pricing, scheduling, methodology, and online vs. in-person classes, in both English and Spanish. The studio can't watch the inbox around the clock, prospects expect fast answers, and a generic auto-reply or a chatbot that invents course details would cost real enrollments.
The Solution
A two-layer router sends quick pleasantries to Claude Haiku for fast, low-cost replies and real questions to Claude Sonnet with RAG context — so answers about pricing, scheduling, and methodology are grounded in New York English's own bilingual content, never invented, and delivered in the prospect's detected language. When someone wants a person, Meta's Handover Protocol passes the thread to the studio's Page inbox and auto-resumes the bot after a 30-minute timeout. HMAC-verified webhooks, Sentry monitoring, and a /health endpoint keep it production-solid.
