Your reply rates are lower than they should be. It's not your targeting. It's your inboxes. We monitor your infrastructure and automatically swap out underperformers.

The Problem

Your sequencer
won't tell you this.

Some of your inboxes are silently killing your campaigns. They drag down reply rates week after week. You'd never know.

01

Hidden underperformers

Inboxes going to spam or getting poor engagement. Your sequencer shows averages, not which inboxes are the problem.

02

Manual rotation is slow

By the time you notice a drop and swap inboxes manually, you've already lost weeks of potential replies.

03

No way to measure impact

Even if you do rotate, how do you know if it helped? There's no attribution for inbox performance.

The Delta

3 bad inboxes.
47 missing replies.

A typical 50-inbox campaign has 3-5 inboxes quietly underperforming. At a 3% reply rate, that's 40-60 replies you're not seeing - every single month.

We find them, swap them out, and track every reply you get back. The delta is the number that matters.

30 minutes. No pitch. Just a clear picture of what's costing you replies.
