According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), SpamExperts (SolarWinds) is the mailbox provider for 2,663 domains — 0.40% of 658,711 domains with MX records. Detection method: primary MX record (lowest preference).
SpamExperts is a managed email filtering and security platform operated by SolarWinds, commonly deployed by hosting providers and registrars as a protective layer for their customers' mailbox infrastructure. It functions as a mail gateway, intercepting and screening messages for spam and malware before they reach end-user inboxes.
SpamExperts' footprint is concentrated among smaller and mid-market hosting platforms, predominantly in the .com namespace, and has been declining in overall market share. When senders encounter SpamExperts as an MX provider, it typically signals a smaller or registrar-hosted infrastructure where authentication rules, filtering behaviour, and feedback mechanisms may differ from those at major consumer and enterprise ISPs.

Because SpamExperts is predominantly used by smaller hosting providers and registrars, deployments often lack formal feedback loops (FBL) or abuse reporting integration with major ISP networks. This means senders may not receive timely complaint signals from SpamExperts-hosted mailboxes, making reputation monitoring and list compliance harder to track in practice.
