Automated warmup builds your sender reputation across a network of real inboxes — so your cold emails and campaigns actually get seen.
Mailbox providers route mail from low-reputation domains straight to spam — where even your best campaign generates zero replies. Reputation is earned through consistent, positive sending history. Warmup builds exactly that, on autopilot.
Link any Google Workspace, Microsoft 365, or custom SMTP/IMAP inbox in under a minute. OAuth or app password — your credentials are encrypted at rest.
Choose a ramp curve — conservative, balanced, or aggressive. We start with a few sends per day and scale gradually so providers learn to trust your domain.
Your mailbox exchanges genuine, human-like conversations with a network of verified inboxes. Messages get opened, replied to, and pulled out of spam — the signals providers reward.
Track inbox-placement rate, spam rate, and reputation in real time. As your sender score rises, your real campaigns start landing where they belong.
Thousands of verified mailboxes across Gmail, Outlook, and private domains — not bots. Conversations look and behave like real human email.
Daily send volume increases automatically based on how your reputation is trending — never faster than providers tolerate.
When a warmup email lands in spam, the network opens it and marks it 'not spam', teaching the provider to trust you.
Continuous SPF, DKIM, and DMARC checks with a guided fix wizard. Misconfigured auth is the #1 deliverability killer — we catch it.
Inbox-placement rate, spam rate, reply rate, and reputation trend — per mailbox, updated continuously.
Runs entirely in the background on a schedule. No manual sending, no spreadsheets — just steadily improving deliverability.
Even a perfectly warmed domain lands in spam if SPF, DKIM, or DMARC are wrong. The platform continuously monitors all three, scores your spam-trigger words, checks blacklists, and walks you through every fix.
Illustrative — your live numbers appear in the dashboard.
New or cold sending domains have no reputation, so mailbox providers route their mail to spam. Warmup gradually builds a positive sending history — consistent volume, opens, and replies — so providers learn your domain is trustworthy and place your mail in the inbox.
Most domains see meaningful improvement in 2–4 weeks. Brand-new domains or those with prior spam history take longer. The platform ramps automatically and you can watch the reputation trend climb in your dashboard.
No — the opposite. The network sends human-like, low-volume conversations that generate positive engagement signals (opens, replies, not-spam marks). The adaptive ramp never pushes volume faster than providers tolerate.
Google Workspace, Microsoft 365 / Outlook, and any custom domain over SMTP/IMAP. You can connect multiple mailboxes and warm them in parallel.
Credentials are encrypted at rest, and we only send/receive the warmup conversations needed to build reputation. You can disconnect at any time.
Manual warmup is slow, error-prone, and gets your replies stuck in spam where they generate no positive signal. The network guarantees engagement (opens, replies, spam rescue) that you can't replicate by sending into the void.
They dramatically improve results, and the platform monitors all three with a guided fix wizard. You can start warmup while you sort out auth — we'll flag exactly what's missing.
Yes. Paid plans support multiple mailboxes warming in parallel, each with its own strategy, schedule, and analytics.
Keep a light maintenance warmup running to preserve reputation while you send real campaigns. Reputation decays if a domain goes silent, so ongoing low-volume warmup protects your inbox placement.
There's a plan for every team size — see the pricing page for mailbox limits, daily send limits, and features. You can start small and scale as you add mailboxes.
Connect a mailbox, pick a strategy, and let the network build your reputation while you focus on writing emails worth sending.
