Mailboxes send and reply inside your own peer network on a schedule tuned per provider, climbing only as each placement checkpoint clears: twelve weeks from a first send to full volume.

Nobody schedules a send. The curve does it.
Every mailbox walks the same curve, gated by the same checkpoints, with no spreadsheet and no calendar reminder anywhere in the process.
A curve a receiver reads as growth
Mailboxes send and reply across a private peer network, climbing week over week the way a business grows rather than the way a blast arrives.
No mailbox carries the whole send
Volume rotates through the roster on a schedule, so no single sender takes a disproportionate share while its reputation is still thin.
Your fleet talks to your fleet
Warmup traffic moves between mailboxes inside your own account, never pooled with other customers and never inheriting somebody else's reputation.
You can see where every mailbox sits
Daily volume for the whole cohort is laid out week by week, so a mailbox in week six at 22 sends a day is something you point at rather than infer.
Three stages, twelve weeks.
None of it needs a schedule that you have to maintain.
Step 1: Enrollment is automatic
Every mailbox joins the day it is created, opening at four to six sends a day rather than at whatever the campaign wanted.
Step 2: The peer network does the work
Sends, replies, forwards and the occasional flag-as-important move between your own mailboxes on the day's schedule.
Step 3: The checkpoint decides the next step
Volume increases week over week only once a placement checkpoint clears. Miss one and the curve holds, or steps back a level.
Twelve weeks, and every step has to be earned.
The curve is tuned per provider and opens at a handful of sends a day, advancing only while replies and engagement hold up. A schedule that ignores its own signals is not a ramp, it is a countdown.
The curve flattens on bad signals
If open and reply rates dip, the ramp holds instead of taking the next volume step because the calendar said it was due.
Replies count, not only sends
The peer network replies, forwards and occasionally marks a message important, because a mailbox that only emits mail does not look like a person using one.
Pacing differs per provider
Ramp speed is tuned separately for each major mailbox provider, since they do not read a new sender the same way or on the same timescale.
Checkpoints gate the next week
A mailbox has to clear a weekly placement threshold before its volume ceiling moves at all. The gate is the mechanism, not a formality.
What people ask before trusting a ramp
You can request an accelerated curve, and the checkpoints still apply. A faster ramp changes the target volume per week; it does not switch off the placement gate that decides whether you actually get there.
No. The peer network is scoped to your own fleet, up to 60 mailboxes, so nothing sent during warmup is exchanged with another account's senders.
The ramp holds at the current volume, sometimes steps back a level, and the alert names what dropped (placement, replies or bounce rate) before it tries to advance again.
No. A mailbox with an established sending record skips the early stages and joins the curve nearer full volume, rather than restarting at four sends a day.
Yes. A pause holds the mailbox at its current volume, and resuming continues the curve from that point instead of restarting at week one.
Build the reputation before the campaign needs it.
Warmup claims every mailbox the day it is created: no schedule for you to build, and no reminder for you to miss.
