AI Deliverability & Mailbox Health
Your best email means nothing in spam.
It doesn’t matter how good the messaging or targeting is if no one sees it.11x treats deliverability as core infrastructure, not an afterthought. Domain setup, warming, monitoring, and rotation are all handled automatically on the platform.

Overview
Primary domain protected
11x manages your full deliverability stack. Sending domains are set up, warmed, rotated, and monitored automatically.
Volume scales cleanly
Private sending IPs, capacity tracking, and automatic rotation keep delivery rates high at any volume.
Fully Managed
See mailbox health in real time. Or better, let 11x automatically manage the entire deliverability stack.
Trusted by leading GTM teams:
Emails that land because the infrastructure is built for it.
Automatic setup, warm-up and rotation
Domains are provisioned with DKIM, DMARC, and SPF configured, then warmed automatically. When a domain's health dips, 11x pulls it from sending and rotates in a warm replacement.
Inbox placement testing
11x tests whether emails are hitting primary, promotions, or spam before volume goes out. Campaigns adjust based on real placement data.
Blacklist monitoring and recovery
When a domain gets flagged, 11x detects it, pauses sending, and cools down the affected mailboxes. Recovery starts automatically.
Plain text by default
Emails are written to read like a human sent them. No tracking pixels, no heavy formatting, no images that trigger filters. Every message is unique so no two emails look the same.

"We evaluated twelve solutions and 11x was the only one with real AI personalization. Without 11x, we’d still be pushing generic outreach and bleeding limited budget just to hit our numbers."
