Troubleshooting

Updated Aug 2026

Fixes for the most common snags, and how to reach a real person.

My simulation emails aren’t arriving

  • Check the sending domain is active, every DNS record has to verify. See Connect a sending domain.
  • Confirm the targets are on your own verified domain; HukProof blocks sends to personal-inbox providers and to addresses outside your domain by default.
  • A brand-new account is reviewed before its first real campaign. You can build drafts throughout and send up to 20 test emails after 24 hours; full sending unlocks once we verify your signed authorization letter. See Account review & sending unlock.

A domain won’t verify

DNS changes take time to propagate, from a few minutes to a few hours. Double-check each record was pasted exactly, with no extra spaces, then wait and re-check.

Someone didn’t get their training

  • Training links go to the person’s work address, confirm it’s correct on the Targets page.
  • Check they aren’t on the Suppression list.
