Email verification that pays for itself
Every bounce costs you reputation. MailExchange checks each address the way a mail server would, without ever sending a message, so you only send to inboxes that exist.

Clean lists mean fewer bounces, better inbox placement, and more of your campaigns actually read.
Clean a whole list in minutes
Upload a CSV or paste your addresses. We sort every one into deliverable, risky, undeliverable or unknown, and tell you why.
- Cut bounces by removing dead mailboxes and domains
- Spot catch-all servers that accept anything and bounce later
- Flag role and disposable addresses before they hurt you
- Duplicates removed and never charged
Verify at the point of capture
One HTTP call returns the state, the reason and the details you need to decide. Drop it into a signup flow, a CRM sync or your own sending tool.
- Simple JSON: state, reason, score, MX, role, free, disposable
- Bulk endpoint for whole lists in one call
- Same engine as the dashboard, so results always match
Verify leads before they hit Instantly or Smartlead
Cold email platforms pause campaigns and burn domains when bounces climb. Clean every lead list before you import it, and keep your sending domains healthy.
- Catch-all detection for the risky leads Apollo exports are full of
- Export straight back to CSV with a state on every row
