The Silent Revenue Killer
Why your open rates are tanking
Most agencies run their senders until they burn. Once an account hits spam, it's too late—your domain is torched, and your leads are lost.
- The "Run 'til Dead" Strategy
- You send emails until open rates drop to 20%. By then, Google has already flagged your domain. Recovery takes weeks, if it happens at all.
- Manual Checking Hell
- Logging into 50+ inboxes to check health scores daily? It doesn't happen. Problems go unnoticed until clients complain.

What Our Customers Say
"We were manually checking 120 inboxes every week. Last month, InboxBench caught 4 accounts going bad before we did and swapped them automatically. At $50/domain, it paid for itself in week one."
