Engineer cuts AI inbox costs by limiting LLMs to judgment tasks, not email logistics
A software engineer overhauled their email automation workflow by reassigning responsibilities between code and large language models. The core insight was that deterministic tasks — such as routing rules, deduplication, retry logic, and sync state — should be handled by code, while LLMs like GPT-5 or Claude are reserved only for genuinely ambiguous decisions like classifying unclear messages or drafting replies. The engineer noted that repeatedly querying frontier models for repetitive checks is effectively expensive amnesia rather than intelligent automation. Google's Gmail API quota costs — ranging from 2 units for history lookups to 100 for sending — were highlighted as design signals encouraging event-driven, selective fetching over constant full-inbox polling. The revised architecture is described as cheaper, more debuggable, and more resilient than treating an LLM as the central orchestrator of an inbox pipeline.
