SpamExperts, also known as AntiSpamCloud, is an email filtering and security platform that organisations integrate into their mail infrastructure to provide antispam, antivirus, and email security functions. Rather than replacing existing mail systems, it typically operates as an additional filtering layer, connecting to email flows via standard protocols including SPF.
Across the Tranco top-1M, SpamExperts exhibits a footprint concentrated amongst smaller and mid-market organisations rather than the largest global brands. The service is geographically distributed internationally, with presence across numerous TLDs but concentration in .com domains and a regional skew towards North America. Its frequent pairing with self-hosted mail infrastructure indicates it commonly augments organisations operating their own email systems directly.

When SpamExperts appears in a domain's SPF record as an include mechanism, it signals that domain's mail is routing through its filtering infrastructure. From a deliverability perspective, this affects the reputation and authentication pathway of outbound mail, as messages are identified as passing through SpamExperts' IP space and filtering policies. Recipients encountering mail from domains with SpamExperts in their SPF records can recognise this as evidence of upstream email security filtering, which may be relevant when investigating delivery issues or assessing the email security practices of a sending organisation.
