Every email we return undergoes a triple verification process to ensure its validity. If an email is flagged as invalid by one provider, we continue checking until a valid email is confirmed or all options are exhausted.

Email Statuses

We categorize emails into four statuses:

DELIVERABLE: 1% bounce rate.

HIGH_PROBABILITY: 9% bounce rate.

CATCH_All: 26% bounce rate.

INVALID: Likely to bounce.

“most_probable_email” Field

This field returns the email with the lowest bounce rate. If multiple valid emails are found, we prefer the one with a domain closest to the user-entered domain. INVALID emails are excluded in this result.
