What problem does it solve? Running cold email campaigns without a fixed operating cadence leads to missed deliverability issues, unanswered positive replies, and no learning across campaigns. This Skill prescribes exactly what to run and when so cold email operations stay consistent week after week. ## Core Features & Use Cases - Calendar-Based Cadence: Defines six recurring calendar events covering Monday deliverability audits, Wednesday positive-reply sweeps, Friday campaign retrospectives, biweekly inbox rotation, monthly spam placement tests, and quarterly experiment reviews. - Prescribed Actions Per Event: Each cadence entry specifies the exact command to run, the metrics to review (reply rate, bounce rate, inbox placement), and the decision thresholds to act on. - Experiment Logging: Directs logging of campaign results to JSON experiment files and quarterly retrospectives that feed future experiment design. - Use Case: An operator with live Smartlead campaigns uses this playbook every Monday to audit fleet reply rates against the 1% rule, pause campaigns with bounce rates above 2%, and escalate failures into incident response. ## Quick Start Set up the six recurring calendar events listed in the playbook, then run the Monday deliverability audit against your active campaigns.
