ColdMailServer
Features & Capabilities

Outbound infrastructure, engineered for delivery.

Every tool and system we build is designed with a single objective: to get your outbound cold emails safely and consistently into the primary inbox.

Infrastructure

Fully Isolated Mail Servers

Every customer gets a dedicated, isolated server container. Your reputation, IP pools, and delivery queues are 100% yours, preventing cross-user blacklisting.

Deliverability

No Warm-up Required

Bypass typical 4-week warm-up schedules. Our mail servers run on pre-aged, pre-warmed IPs with established reputation scores so you can send from day one.

Productivity

Built-in Unibox

Consolidate all incoming responses from hundreds of mailboxes and domains into a single unified feed. Never miss an interested lead again.

Deliverability

Deliverability Dashboard

Complete real-time telemetry monitoring bounce rates, spam complaints, DKIM alignment, SPF validation, and domain health indices.

Infrastructure

Unlimited Scale

Add unlimited domains and mailboxes on every plan. Scale your domain rotation strategies without paying per-mailbox seat licenses.

Infrastructure

Forwarded Email Support

Natively handles email forwarding rules and webhooks using Sender Rewriting Scheme (SRS), keeping authentication alignment fully intact.

Productivity

SMTP & IMAP Support

Standard mail protocols that plug natively into any sales outreach platform—Instantly, Smartlead, Lemlist, Apollo, Clay, or custom scripts.
