Works With Your Inbox

INBOX-POWERED

Uses your existing email inboxes as the sending source for cold emails. All outbound messages are sent directly from these inboxes. No new inboxes are created or required.

Cold Email Without Subscriptions or Limits

Actually Reach the Inbox — Without Monthly Fees

There are plenty of tools for sending cold emails — and most of them promise to make it easy. Chances are, you’ve tried a few already. The problem is that many cold email tools become expensive, overly complex, or limit what you can do.

PrimaryInbox is different. It’s built to keep cold email simple, reliable, and inbox-focused. Deliverability is built into how the system works, not added on later. There are no monthly subscriptions, no feature gating, and no forced upgrades. All features are available from day one, so you can focus on sending emails — not managing software.

Take a look around and see if PrimaryInbox fits your workflow.

PrimaryInbox completely changed our cold outreach results. We went from constantly worrying about spam issues to consistently landing in the primary inbox. Reply rates improved within the first two weeks.

We tested multiple tools before PrimaryInbox. Deliverability here is noticeably better, and campaigns stay stable even at higher volumes. It’s become a core part of our outbound stack.

Inbox placement used to be our biggest bottleneck. With PrimaryInbox, emails actually reach prospects instead of disappearing. That alone made a massive difference for our pipeline.
