Run a single email verification to check its deliverability. Authenticate every request with your API key in the x-api-key header. For batch operations, use the Verify Bulk Emails endpoint.
Enrow performs determinist verifications that verify even catch-all emails. This means passing the results through a debouncer afterwards isn’t needed.
