Which HubSpot Contact fields does Warmly update?

Last updated: September 2, 2026

If you’ve enabled Create or update contacts in your HubSpot integration settings, Warmly can sync data to the following standard HubSpot Contact fields:

Standard HubSpot Field

Behavior when creating or updating a contact

Name

Fill if empty. If the value was collected in chat, Warmly overwrites the existing value with the value provided by the visitor.

Email

Never overwritten. Warmly uses this value to match the contact record.

Title

Fill if empty. If the value was collected in chat, Warmly overwrites the existing value with the value provided by the visitor.

Owner

Fill if empty. If an owner already exists, Warmly will never change it.

Phone*

Fill if empty. If a phone number already exists, Warmly will never change it.

Mobile Phone*

Fill-if-empty

Fax*

Country*

* These fields are only synced when Sync back address and phone numbers is enabled. This setting controls whether Warmly syncs address and phone data when creating a new HubSpot contact.

Custom fields

If you’ve mapped custom fields in your HubSpot integration, the following rules apply:

  • Fields mapped to chat responses: Warmly overwrites the existing HubSpot value with the value provided by the visitor in chat.

  • Fields with a default value: The default value is only written when creating a new record. It will not overwrite an existing HubSpot value.

  • Warmly custom fields: These are always overwritten to ensure HubSpot has the latest values from Warmly.
