Hunter Email Verifier

Request a deliverability assessment for one email address and return Hunter’s complete assessment.

Setup

Select your Hunter account in Request Hunter email verification and allow hunter.email_verifier. Run with the Email address you want to assess. In n8n, select Hunter credentials and replace the example address in Hunter. Your account needs an API key.

Each run makes one verification request. The result includes Hunter’s status, score, SMTP checks, source information and any other returned assessment fields. A result such as invalid, accept_all or unknown is still an assessment; the workflow does not turn these values into a success-or-failure decision. Verification does not send an email message.

Hunter can return a previous verification from up to one month ago. Inspect the returned verification date; it can be null when no verification was performed. This assessment does not guarantee delivery to an inbox.

If Hunter is still verifying after its request window, it returns a pending response. This workflow stops without claiming a completed assessment. It has no automatic polling or retry; check the result before running again. A rejected request or malformed response also stops the run.

Changes to the source

• Replace the example email with user configuration.
• Check that a completed assessment is present and expose it as an Open Flow output.
