Verify leads wherever you send from

Cold email tools pause campaigns and burn domains when bounces climb. Clean every list before it goes in, with a step-by-step workflow for each tool.

Stay under Instantly's 5% bounce auto-pause by verifying leads before import.

Smartlead sends to catch-all leads by default. Verify first and decide yourself.

Apollo's "verified" emails still bounce. Re-verify every export before it hits a sequence.

Every integration works the same simple way

Export your leads as a CSV from your lead source or sending tool.
Verify the file in MailExchange. Every row gets deliverable, risky, undeliverable or unknown.
Import only the rows you want back into your sending tool. Your other columns are kept.

Prefer to automate it? The API lets you verify leads in your own pipeline before they're pushed into a campaign.
