Ready when the evidence says so, not when a date passes
Every message leaves our network for real accounts at Gmail, Yahoo and AOL, and those accounts report where it landed. A mailbox is called campaign-ready when that evidence says it is reaching the inbox.

Ready when the evidence says so, not when a date passes
Inventory inboxes arrive with this already behind them. For domains you bring, you pick how hard the ramp pushes — and a mailbox is called campaign-ready when seed accounts prove it is reaching the inbox, not after a fixed number of days.
Messages per day, per mailbox
Concave on purpose — a linear ramp spends its steepest relative increases in week one, which is the week that matters.

Every message leaves our network
Warming writes to real accounts at Gmail, Yahoo and AOL, over the real internet. Not to other mailboxes on our own servers — that mail is delivered locally and never reaches a provider, so it cannot build anything at one. Most warmup tools spend most of their volume that way.
Measurement decides when it is ready
Those same accounts report where each message landed, so the whole day’s volume is measured rather than a sample of it. That is the graduation test: ramp finished, sends actually delivered, and enough of them in the inbox. A mailbox nobody has measured never gets called ready for simply being old.
Engagement that reads as human
Around 95% of messages get opened, a fifth get starred, three in four get a reply — after a delay drawn from a long-tailed distribution, never in under a minute. Sends are jittered inside working hours and spaced at least 90 seconds apart.
Spam rescue
When a warming message lands in the spam folder, we sign in to the receiving account, move it out and mark it read. A recipient rescuing mail from spam is the strongest positive signal a sender can earn — and it only counts because the account doing it is a real one at the provider.
Automatic hold when it goes wrong
If more than half of measured messages land in spam across a week, the ceiling drops to five and the mailbox is flagged. Sending the full target while filtered makes the problem worse, not better.
Quiet at weekends
Saturday runs at 30% and Sunday at 20%. A mailbox sending identical volume seven days a week for a fortnight looks like exactly what it is.
Why most warmup does nothing
Almost every warmup tool sends the bulk of its volume between mailboxes on its own servers. That mail is handed over locally and never crosses the internet, so Gmail never sees it — the ramp happens, and the only party whose opinion matters misses it. Ours goes to real accounts at real providers, every message, which is why the number we put in front of you is measured placement rather than messages sent. Reputation still needs your actual campaigns; warming makes sure the account and the curve are not what gets you filtered first.
Warm mailboxes you already own
Warming is priced per inbox rather than per mailbox we host, so connecting a Gmail, an Outlook or a mailbox on your own server costs the same $0.60 and gets the same treatment.
Gmail
Connect a Google Workspace or Gmail mailbox and it gets the same ramp, the same real-provider conversations, the same measurement.
Outlook
Microsoft 365 and Outlook.com mailboxes warm against the same seed accounts, at the same price, with the same graduation test.
Your own server
Any mailbox with SMTP and IMAP — cPanel, a VPS, a niche provider. Warming is priced per inbox, so the mail host never changes the bill.
Standard — 14 days
For a domain with no history. Starts at two messages a day and grows by a concave curve, so the steepest relative increases never land in week one.
Accelerated — 7 days
For aged domains or mailboxes already sending. Starts at five a day and pushes harder, because the history can carry it.
