Re-verifying with InsightX+

After a job finishes, some results may still be worth a deeper look with InsightX+'s enhanced verification. MailInsightX only offers this for results where that deeper check would genuinely produce new information - not for every "unconfirmed" status.

Which results are eligible

Only these are eligible for InsightX+ re-verification on a completed job:

  • Valid results that haven't already been SMTP-confirmed
  • Gibberish (Risky) results
  • Unverified (DNS Timeout) results, but only when the DNS failure looks genuinely transient rather than a repeated, consistent resolver error for that domain

Warning

Role-Based (Risky) and Parked (Risky) results are deliberately not eligible for re-verification, even though neither one went through InsightX+'s enhanced verification. Both statuses are decided by checks that don't change on retry - a parked domain can never reach that enhanced verification regardless of credit pool, and mail servers commonly greylist or tarpit generic role-based addresses in a way that keeps producing the same outcome. Offering these for re-verification would let a job spend InsightX+ credits repeatedly for the same result every time, with no new information gained.

How it works

Starting a re-verification creates a new job containing only the eligible emails from the original job, run with InsightX+ enabled. It costs one InsightX+ credit per eligible email, the same as any other InsightX+ verification.

If your account doesn't have enough InsightX+ credits for every eligible email, the request is rejected up front (no partial charge) - add credits via the Billing tab first.

See the Verification Status Glossary for what each status means, and Two Credit Pools: Standard vs. InsightX+ for how credit pools work generally.
