A campaign can be approved, polished, and still underperform because it lands in Promotions, hits Spam, or carries copy that quietly kills response. InbXr helps agencies and email marketers catch those problems before the email goes out. And monitors your deliverability 24/7 after you hit send.
Bounce rate tells you what broke last time. Signal Score tells you what will break next time. Built on 7 inbox signals including MPP-adjusted real engagement and acquisition cohort quality. Two dimensions no other platform measures.
Get my Signal Score → Or read the full breakdown of all 7 signals →"My open rates dropped 40% and nothing changed."
Your open rate was already wrong before it dropped. Apple MPP inflated it for years. When real engagement fell, the gap between the number and reality finally became impossible to ignore. Signal 02 would have flagged it 30 days earlier.
"I verified my list, authenticated my domain, and still got flagged."
You were clean on Signals 01 and 06. The other 5 were broadcasting problems your stack was not built to hear. Acquisition Quality and Spam Trap Exposure were the ones that got you.
"I inherited a 200k list with no history attached."
Upload it as a CSV. Get a full 7 Signal reading in 60 seconds. Most inherited lists fail 3 signals before the first send. Now you will know which 3 before you touch them.
"I lost my sender score and it took months to recover."
Pre-send Check and Early Warning read the exact conditions that produce that event before you send, not after. Once is expensive. Twice is avoidable.
