This page is kept as a narrow support reference from the older GTM Stack corpus. It can still be useful for one-off operator questions, but it is not one of the curated flagship entries. Start from the curated question set if you want stronger workflow guidance.
Since HubSpot only does exact matching (unlike Salesforce's 'contains' function), try using address or phone number as your primary matching keys instead of domain/company name - this works much better for SMBs and chains. For more advanced matching, consider building an Apify actor that pulls HubSpot data via API and runs fuzzy matching using multiple signals like domain normalization, company name similarity scoring, phone number normalization, and address geocoding with confidence scores. You can also export HubSpot records to Clay for formatting and then re-import via Clay's HubSpot integration.
