Why was my Contact automatically associated with a Company in HubSpot CRM?

HubSpot CRM aims to make your life easier by automatically associating contacts to companies in your CRM and creating companies for you if one does not yet exist. You can find this setting called "Automatically create and associate companies with contacts" under Settings > Companies

How it works

This setting looks at the email address domain of the contact and matches this to the Company Domain Name property on the company record. When you add a new contact while this setting is turned on, two things can happen:

  1. If a new contact is added to the CRM and a company already exists with a domain name that matches the domain ( in the contact's email address, the contact will be automatically associated with that company.
  2. If a company does not already exist to match the domain of the contact's email address, a new company record will be created and populated with information from our database

For example, if you add a contact with the email address, we will take the domain part of the email address "" and look for a company record with the Company Domain Name value "" If one exists, the contact will be associated with that company. If one does not exist, a new company will be created. 

Please note: This setting ignores contacts with freemail email addresses (,, etc). In these cases, HubSpot will also look at the Contact property Website URL to see if we can match that property value to the Company Domain Name on the company record.

When you first enable this feature, you will be asked if you would like to create company records for exisiting contacts. We will not overwrite any existing company-contact connections. Once you select yes, our associator will go through contacts creating the connections.


To prevent contacts from automatically being associated with a company: 

  • From your HubSpot Sales account, navigate to Settings.
  • Click Companies in the left side menu.
  • Click the switch for Automatically create and associate companies with contacts to toggle it off (when it's OFF the switch will be grey instead of blue and no longer have a check mark.)
