Key facts

Bluehost is a web hosting provider that operates email services for its customer domains. The service is internationally distributed with heavy concentration in the .com namespace and hosts predominantly smaller websites rather than large enterprises.

Bluehost's position in the long tail of the Tranco top-1M list means email senders routinely reach Bluehost mailboxes as part of broad recipient populations, though individual domain volumes are typically modest. The frequent co-location of Bluehost hosting with third-party mail services such as Mailjet (Sinch) means that email filtering on Bluehost infrastructure is often shaped by external service configurations in addition to Bluehost's own policies.

Shared infrastructure and reputation spillover

Bluehost's email service operates within shared hosting infrastructure, where multiple customer domains coexist on the same mail servers and IP addresses. This shared context means sender reputation filtering is sensitive to collective behaviour across the entire hosting provider's customer base, and a single misbehaving domain can trigger broad throttling that affects other Bluehost customers.
