Skip The Warmup Wait. Launch Your Campaign This Week.
A new inbox normally needs weeks of gradual warmup before it's ready for outbound sending. Ours already have that preparation done—authenticated and with existing sending history—so you connect and launch instead of spending weeks building the infrastructure yourself.
What Does Pre-Warmed Actually Mean?
A lot of customers assume buying a domain or inbox means they're ready to send. Here's what's actually different.
New Inbox
- Authentication & configuration needed
- Gradual warmup required
- Sending history built from zero
- Volume increased gradually over weeks
Pre-Warmed Inbox
- Infrastructure already prepared
- Existing sending history
- Authentication already configured
- Faster handoff to your campaign
"Pre-warmed" doesn't mean unlimited or instantly risk-free sending. You still need responsible sending practices, appropriate volume, good data and good copy.
Why Starting From Fresh Inboxes Slows Down Your Campaign
You already have a campaign to launch. You shouldn't have to spend weeks building the sending infrastructure first.
Waiting Weeks Before Launch
New inboxes need a gradual warmup period before they're appropriate for outbound sending.
Building Warmup Infrastructure Yourself
You'd have to configure accounts, domains, authentication and warmup on your own.
Managing Multiple Inboxes
Scaling from a few inboxes to dozens can turn into an operational headache.
Monitoring Sending History
Warmup isn't simply flipping a switch—it needs to be tracked and managed.
Campaign Launch Delays
The campaign may be ready while the infrastructure isn't.
Technical Setup Work
DNS, authentication, inbox configuration and outreach-platform connection all take time.

What We Guarantee — And What We Don’t
Warmed To Safe Thresholds
Every inbox is warmed to safe sending thresholds before handoff, or we keep warming at no extra cost.
We Don’t Guarantee Inbox Placement
Warming reduces the risk that comes from starting on a cold, unauthenticated inbox, but inbox placement also depends on your copy, targeting, volume and list quality.
A Sending Limit We Stand Behind
We recommend up to 20 sends per inbox per day to maintain your sender reputation and allow safe, sustainable scaling—rather than quoting a volume that burns the inbox.
The 3-Month Minimum, Explained
The value of a warmed inbox comes from sustained history—the commitment protects that reputation and the quality of our shared inbox network. After three months your plan continues month-to-month.
