What’s the importance of domain-level health analysis?

Domain-level analysis evaluates entire domains rather than individual addresses. It identifies domains with: high bounce rates across your list, poor reputation, temporary delivery issues, or systematic problems affecting all addresses.

Benefits include: efficient bulk decisions (suppress entire problematic domain rather than address-by-address), early warning of domain reputation changes, and identification of potentially fraudulent domains used in signup fraud.

Domain health complements address validation. An address might pass individual validation but reside on a domain with poor reputation or operational problems. Evaluating both levels provides more complete list quality assessment.
