SpamExperts, operating under the brand AntiSpamCloud, is a cloud-based email filtering and security service that acts as a third-party MX handler. Organisations deploy it to inspect inbound mail for spam, malware, phishing, and policy violations before messages are delivered to end users.
Domains using SpamExperts configure it as their primary MX record, so inbound mail transits through its infrastructure first. The service is prevalent among smaller and mid-market organisations globally, particularly across .com and other major top-level domains, which means senders and email administrators regularly encounter SpamExperts filtering policies when corresponding with affected recipients.

Because SpamExperts intercepts mail at the SMTP ingress point, senders whose messages are rejected or delayed must address underlying reputation signals—such as SPF/DKIM alignment, sender history, and complaint rates—rather than SpamExperts-specific quirks. The service's filtering thresholds may differ from those of native mailbox providers, but rejection typically reflects genuine reputation or content issues rather than constraints unique to the filtering service.
