Best of the inbox: a 30-day warm-up log, day by day
Most warm-up advice is a vague curve. This one is an actual diary with daily volumes and the placement readout.

🚀 Deliverability
— Cold domain to 50k/day in 30 days — Started at 50 sends/day to most-engaged openers, roughly doubling every two days, holding whenever the seed-test inbox rate dipped below 90%. Worth your time: they logged the exact day Gmail placement wobbled (day 11, after a 1.9x jump) and how they paused to recover.
— The 'engagement-first' ordering — Sent to 60-day openers before anyone else; that cohort's opens kept the early reputation signal clean.

Made the cut for being a log, not a theory. You can copy the schedule line by line.

Saved you ~3 hours of stitching together warm-up threads that never agree on numbers.
