Customer Email Drafting with Claude Code: Cost Controls
A production playbook for customer email drafting in cross-industry operations using Claude Code: cost controls, run-scoped inputs, logs, typed results, and artifacts.
Audience: Customer-facing teams
The problem
Customer-facing teams need customer email drafting to run repeatedly against tickets, account context, policy, and tone examples. In cross-industry operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Set explicit limits for customer email drafting: input size, run time, tool calls, artifacts, retries, and concurrent runs per organization.
Tradeoffs and failure modes
Limits reject pathological runs, but they keep one workflow from turning into an unbounded infrastructure bill. For customer email drafting, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
