Who it’s for
Who is InfraBoxes for?
Built for teams that live on cold email:
Deliverability timeline
How we keep you inbox-ready
Four steps that stay green so every new batch of domains keeps landing in the inbox.
Step 1
Domain verified – Connect domains and mailboxes in a few clicks. DNS, SPF, DKIM, and DMARC are checked and aligned in minutes.
Step 2
Warmup complete – Aged IP pools and premium warmup flows build reputation automatically over ~14 days.
Step 3
Sequence live – Auto-throttled sending starts with inbox placement testing as you ramp volume.
Step 4
Burn alerts clear – We monitor bounces, replies, and placement to warn you before deliverability slips.
Features
Built for cold outreach teams
Private infrastructure, inbox-style controls, and automations tuned for outbound sequences.
Isolation by design
Every 10 domains live on their own dedicated stack—IPs, servers, and safeguards—so one bad sender never drags the rest down.
Domain burn alerts
We track warmup reputation, inbox placement tests, reply rates, and bounce types to alert you before results drop.
Cold-email-native automation
Auto-throttling, adaptive send volumes, and bounce filtering are built for outbound sequences—not newsletters.
Workflow
Onboard → Protect → Send
Three steps, visible to every teammate, built to keep cold outreach safe while you scale.
Onboard
Connect domains and mailboxes in clicks. We stage them on aged IPs, align DNS, and start warmup automatically.
Protect
Dynamic IP rotation, bounce filtering, and adaptive send volumes keep you out of spam while you scale.
Send
Launch campaigns from an inbox-style console with reply health, placement signals, and burn alerts in one place.
Live reporting
Inbox-ready signals in one view
Sample stats from the InfraBoxes console. Swap in your own data to track placement, replies, domain health, and burn prevention.
