How to disable automatic association of contacts and companies in HubSpot Service Hub
If you have the "Automatically create and associate companies with contacts" setting enabled, HubSpot will check domains of contacts email addresses and create companies if it doesn’t find an existing match. With that setting enabled, after the migration, you will see new companies that HubSpot has automatically created.
How to disable the "Automatically create and associate companies" setting
Step 1. In the top right corner, select Settings.
Step 2. Select Contacts & Companies>Companies. Find Automatically create and associate companies with contacts and switch off the toggle (you know it's off if it's gray).
HubSpot will automatically save your changes. Now, you may continue your data migration. Should you have any questions? Drop us a message in the live chat.
