# The operator playbook and question library

How we diagnose a cold email drop is now written down and shared by the site and the free agent: a decision tree, opposite responses to low replies and a bounce spike, every new variable at 5 a day, rest or replace, and the questions teams bring us, answered the same way in both places. Every guide now ends with a link to add the agent.

## New

- The operator playbook: the decision tree for any drop, the 5, 10, 15 ramp for low replies and anything new, a full rest for a sender-side bounce spike, the rest-or-replace trade-off, replacement as a multi-signal decision, and why the agent asks for your numbers. [The playbook](https://warminboxes.com/blog/cold-email-operator-playbook)

- The operator question library: fifty-odd questions in twelve groups, from replies stopping after a strong start to follow-up cadence, links, opt-outs, catch-alls and scaling safely, each with the checks the agent runs. Also listed on the agent page. [The questions](https://warminboxes.com/blog/cold-email-deliverability-questions)

- Every guide ends with a link to add the free agent to your AI, for ongoing QA and advice. [The agent](https://warminboxes.com/deliverability-agent)

## For AI agents

- WarmInboxes Free MCP carries the operator rules and every library question as notes, including step-by-step guides to connecting WarmInboxes Infrastructure MCP, ordering, and cancelling (by domain, in the app). [WarmInboxes Free MCP](https://warminboxes.com/plugins/free-mcp)
