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.
We classify emails into four categories:
DELIVERABLE: Emails confirmed as valid through a direct response from the mail server. These are the most reliable.
HIGH_PROBABILITY: Emails from catch-all domains that are likely valid based on our triple verification process.
CATCH_ALL: Emails from domains configured to accept all incoming messages (for example, @fullenrich.com). Because the domain doesn’t confirm whether a specific address exists, we cannot verify if it belongs to an individual.
INVALID: Emails that are very likely to bounce.
most_probable_email Field
Returns the email with the lowest expected bounce rate.
If multiple valid emails are available, we select the one whose domain most closely matches the user’s input. INVALID emails are never included.
most_probable_email_status Field
Returns the status associated with the email in the most_probable_email field.
