Prospect packs / email-security prospects for MSPs

13,096 local businesses whose email can be forged, by metro

For MSPs and IT providers who sell email security. We checked the DNS of 15,217 US small-business domains that receive email: 86% publish no DMARC policy or only monitor (p=none), so nothing tells Gmail or Outlook to refuse a forged invoice in their name. Each row in a pack carries the evidence - the MX host, the SPF record, the DMARC record or its absence - so your first call can name the exact gap.

13,096exposed businesses

8,816no DMARC record at all

How it works

Email s.n.psaradellis@gmail.com or use a link above. Name the metro, a business type or mail host if you want one, and your company.
Every domain is re-checked before it ships, so one that added DMARC since is dropped, not sold.
No personal email addresses are sold, and any business that asked not to be contacted is removed.
Pay by card after you have seen the free rows: $99 per metro.

Method: MX, SPF and DMARC looked up in public DNS for business websites found on public map listings, October 2026. Advertising agencies and IT firms are left out. Full write-up: who is protected, by business type and email host.
