  "summary": "Transactional email warmup is a critical process for ensuring deliverability and volume ramping. The key steps involve authenticating the envelope sender, using a dedicated sending domain, and ramping up volume gradually based on observed outcomes. A useful five-step plan includes authenticating the sender, starting with real, expected mail to recently active recipients, increasing the eligible share in cohorts, holding or reducing the next cohort based on metric departures from established baselines, and adhering to fixed daily doubling only if justified. It is crucial to hold or reduce the next cohort when a metric departs from its own established baseline. Retention policies must be set before optimizing email storage, as there is no universal number for retention.",
