from the same
list, copy, & offer.
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.
Includes free inbox health audit
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.
Hidden underperformers
Inboxes going to spam or getting poor engagement. Your sequencer shows averages, not which inboxes are the problem.
Manual rotation is slow
By the time you notice a drop and swap inboxes manually, you've already lost weeks of potential replies.
No way to measure impact
Even if you do rotate, how do you know if it helped? There's no attribution for inbox performance.
We fix it.
You check the scoreboard.
InboxFlow runs in the background. Keep your backup pool topped up. We handle everything else.
Continuous monitoring
Every inbox, every campaign. We detect underperformers before they tank your reply rates.
Automatic swaps
Underperformer detected? We rotate in a healthy backup from your pool. No manual work.
