inbox-warm-up-ramp
Use this skill when a new mailbox, domain or seat is about to start cold outreach, or when replies and deliverability drop after volume was raised. Produces a per-inbox daily send ceiling that rises on a schedule, the rules that keep it rising, and the honest way to tell a user why today's limit is low.

Read excerpt
A new mailbox at full volume is a spam complaint with a countdown. This sets
the ceiling, per inbox, and the conditions to raise it.
## The play
1. **Ramp by the age of the inbox, not the age of the campaign.** Week one at
a handful of sends a day; roughly double each week; reach full volume at
about four weeks. Every seat runs its own clock — a new person joining a
mature team starts at week one.
2. **Get volume from more inboxes, never from one working harder.** Two or
three mailboxes on a domain, more domains when you need more volume. A
single inbox pushed past its ceiling is the failure everyone repeats.
3. **Send inside the recipient's working hours, on working days.** Mail
arriving at 3am local time reads as automation to a person and to a filter.
