Operations

Operation Description Cost
Verify Email Verify a single address in real time. Returns status (valid / invalid / catch_all / unknown / do_not_mail), is_disposable, is_role_based, confidence_score (0–100), status_reason, and more. 1 credit per fresh billable result (unknown and cached results are free)
Submit Bulk Job Queue a list of emails for asynchronous verification. Accepts comma/newline-separated addresses and an optional completion webhook URL. 1 credit per fresh completed result
Get Bulk Job Poll a bulk job's status and fetch its results. Free
Get Credit Balance Get your remaining credits and lifetime usage. Free

Example: clean signups before they hit your CRM

  1. Trigger: New row in Google Sheets (or Typeform submission, webhook, …)
  2. MailValid → Verify Email on the address
  3. IF node: {{$json.result.is_valid}} is true and {{$json.result.is_disposable}} is false
  4. True branch: add to your CRM / mailing list. False branch: discard or flag for review.

Compatibility

Requires n8n version 1.0 or above. Tested against the current MailValid API (https://mailvalid.io/api/v1).
