The math

Volume scales by inbox, not by plan tier

Fifteen sends a day per inbox, at three dollars a month per inbox. Stack exactly the capacity you need — and nothing you don't.

Doing this yourself is a ninety-day ramp per domain before the first campaign email leaves. These finished theirs already — and the warming that got them there never stops, so they stay where they are.

How it works

Warmed, measured, then yours

Four steps that all happen before you ever see the inbox — and one of them never ends.

  1. 01

    We register and park the domain

    Months before anyone needs it. The domain ages, the records settle, and the address collects no baggage.

    aged 90+ days
  2. 02

    We warm mailboxes on it

    Real conversations with real accounts at Gmail, Yahoo and AOL — over the real internet, never between our own servers.

    the full standard ramp
  3. 03

    We measure the placement

    Those accounts report where every message landed, so the inbox rate on an inbox is a measurement of its whole ramp — not a sample, not a promise.

  4. 04

    You claim it. Warming never stops

    The conversations and the placement checks keep running after the inbox is yours, automatically, for free — so the number stays a measurement rather than a memory.

Included

Three dollars a month, everything attached

Warming included, forever

Every leased inbox stays on the warming network automatically — the $0.60/mo add-on our own bring-your-own customers pay, free on every pre-warmed address, for as long as you keep it.

15 cold emails a day, day one

Each inbox sends up to fifteen campaign emails a day from the moment you claim it. No ramp on your side, no weeks of waiting for volume.

Placement attached to the address

The measured inbox rate comes with the inbox on the day you take it, and keeps being re-measured while you send.

Ninety-day minimum term

Leased by the month per address, ninety days minimum — the same horizon the warming ran for. After that, month to month.

Unified inbox included

Replies land in the same unified inbox as the rest of your account, with warming traffic filtered out by default.

Outside your plan allowance

Leased inboxes are never counted as plan mailboxes and never billed for warming twice. Claim and manage them over the dashboard, the REST API or MCP.
