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.
