Why Bounce Protect
Other tools give you a score. We give you the reason.
A score tells you something is wrong. An explanation tells you what to do about it.
Other validators
You know something is wrong. You don't know what.
Bounce Protect
You know exactly what is wrong. And what to do about it.
Features
Built for teams that care about deliverability
Multi-signal risk engine
Every risky email gets a full breakdown — disposable domain, role account, domain typo, catch-all server. Not just a score. Every reason, explained.
Domain typo detection
Catches gmial.com, yaho.com, hotmai.com and 20+ common transpositions. Suggests the correct domain so you can fix lists before they bounce.
Explainable results
Every email gets a plain-English explanation of its status. Not 'score: 0.4'. Instead: 'Disposable email provider detected — likely a throwaway address.'
List health score
Weighted deliverability score based on the actual composition of your list. A list full of catch-alls scores differently from one full of disposables.
Role account detection
Flags 50+ role prefixes — info@, noreply@, billing@, careers@, abuse@ and more. Shared inboxes that rarely convert and often filter aggressively.
Clean CSV export
Export enriched lists with status, risk signals, and domain suggestions as additional columns. Ready to import into your CRM or campaign tool.
