About Inbox OneWe Built the Cold Email Infrastructure We Couldn't Find
Inbox One started because setting up cold email infrastructure was broken — buying domains, provisioning mailboxes, configuring DNS, and managing deliverability across dozens of clients shouldn't take days of manual work. So we automated the entire stack.
Our LeadershipFrom Manual Setup to Full Automation
Our founder spent years managing cold email infrastructure for clients — buying domains from registrars, manually provisioning Google Workspace, copy-pasting DNS records, and troubleshooting deliverability issues one by one.
The existing tools were either too basic or too expensive. So we built Inbox One: a single platform that handles domain registration, automated mailbox provisioning, DNS configuration, deliverability testing, and one-click export to every major outreach tool.
Today, over 2,000 agencies and sales teams use Inbox One to power their cold email infrastructure.

SalesforceOur WorkflowManual Infrastructure Setup Was the Bottleneck.
As cold email became critical for growth, the infrastructure behind it remained painfully manual. Buying domains from registrars, provisioning mailboxes one by one, configuring DNS records by hand, waiting weeks for warm-up — it was holding teams back. We built Inbox One to eliminate that friction.

Core ValueWhat Drives Every Feature We Ship
We build for cold email professionals who need reliability, speed, and scale. Here's what guides our decisions.
Infrastructure First
Every feature we ship serves one goal: making cold email infrastructure faster, more reliable, and easier to manage at scale. If it doesn't improve deliverability or save setup time, it doesn't ship.
Automate Everything Manual
DNS configuration, mailbox provisioning, 2FA setup, app password generation — if a human was doing it by hand, we automated it. Your time should go to outreach, not infrastructure.
Deliverability Is Non-Negotiable
We obsess over inbox placement rates, sender reputation, and DNS health. Every mailbox we provision is optimized for deliverability from day one.
Built for Agencies, Not Just Users
Multi-workspace organization, bulk operations, and platform exports designed for teams managing dozens of clients — not just individual senders.
