How does Warmly handle contact-to-company associations in HubSpot?
Last updated: September 2, 2026
When Warmly creates or updates a contact in HubSpot, we associate the contact with one company: the company Warmly matched through IP address or enrichment data.
If a contact is already associated with multiple companies, Warmly does not remove or replace any existing associations. For example, if a contact is associated with Companies A, B, and C, and Warmly identifies the contact as belonging to Company D, we simply add the association with Company D. Companies A, B, and C remain associated with the contact.
What happens if the contact has reached HubSpot's association limit?
HubSpot limits the number of primary company associations a contact can have. If the contact has already reached this limit, Warmly will skip creating the new association.
In this case:
The contact's existing primary company remains unchanged.
Warmly's newly identified company will not be associated with the contact.
Existing contact-to-company associations are never removed by Warmly.
