Three things you can't buy from a mass-market warmup tool — and the reason senior cold-email teams switch.
Connect your sending domain, pick how many of our aged mailboxes receive your campaigns, and let the worker do the rest — through real browsers with isolated fingerprints and residential proxies.
You type the domain you're warming and the sending addresses on it. We don't connect to your mailbox — no OAuth, no SMTP — only the addresses we should look for in our receivers' inboxes.
Choose how many of our 1,000+ aged Gmail mailboxes should receive your campaigns. Selection is random — your campaign never sees the addresses, only that they are warmed and isolated.
Each receiving mailbox is opened in its own Chromium profile with a unique fingerprint and residential proxy. The worker reads inbox + spam, rescues your campaign emails from spam to inbox, and saves a screenshot of every step you can audit later.
Every receiving mailbox sits behind its own residential proxy in a real country, with cookies and login history that look like a person, not a bot.
Health is computed from inbox-vs-spam placement across every receiving mailbox in your campaign, plus the count of emails the worker rescued from spam back to inbox. Every point traces back to a screenshot you can audit.
Every plan includes the full warmup engine — no feature paywalls on the things that actually move inbox rate.
Most warmup tools sit inside your mailbox and send fake replies between accounts in their network. We don't touch your mailbox at all. You keep sending email from your own infrastructure; we read what arrives in our pool of aged Gmail mailboxes, mark it as not-spam where it lands in spam, and prove every action with a screenshot.
No. We never ask for your inbox password — no OAuth, no SMTP, no IMAP. You point us at the domain and the addresses you're warming (just text in the dashboard). We look for emails coming from those addresses inside our receiving pool. Your mailbox stays untouched.
It's about our pool. Every receiving Gmail mailbox we operate runs in its own persistent Chromium profile — own fingerprint (UA, fonts, canvas, timezone), own cookie jar, own residential proxy. Providers see independent humans receiving your email, not a bot farm.
No — selection is random from the shared pool, by design. You can't game your inbox rate by targeting friendly mailboxes; the inbox rate you see is the rate you'd actually get with a cold prospect at a similar provider.
Most cold domains see meaningful inbox-rate movement inside 7 days, with full ramp around 21 days of consistent sending. Already-warm domains plug in and start monitoring immediately.
We only see what arrives in our receiving Gmail mailboxes. From those we read subjects and folder placement (inbox vs spam), take screenshots as proof, and discard the body. Your sender mailboxes are never touched — we have no access.
