SH Consulting scanned 1,055 CRM domains and found 11 listed and 127 candidates on Validity Heatwave. Its analysis highlights persistent listings and cases where lookalike matching can associate unrelated domains, with DMARC and review requests among the recommended next
Key points
- The scan found 11 listed domains, 127 candidates, and 917 clean results among 1,055 domains selected from SH Consulting's CRM.
- 77 domains had 1,521 listed lookalikes attached; some matches were based on name similarity and involved unrelated businesses.
- The article says Heatwave synthetic-warming listings remain even after the activity stops; removal requires a manual review and is limited to cases such as misattribution or impersonation.
- A candidate record may remain visible in the web lookup even when the corresponding DNS answer is NXDOMAIN.
- For listed or candidate domains, the article recommends investigating lookalikes and warmup services, and filing a review only when the listing determination was wrong.
- For clean domains with many lookalikes, it recommends enforcing DMARC and monitoring the primary domain to address impersonation.
