Common errors and fixes
Duplicate emails inflate domain counts
Repeated contacts can make one domain look more important than it is.
Clean and deduplicate the email list first, then run the domain counter.
Subdomains split the same company
Mail domains such as eu.example.com and example.com may represent the same organization.
Combine related domains manually in your follow-up analysis when business grouping matters.
