In your HubSpot account, you can associate contacts with companies by matching the domain in a contact's Email address to the company's Company Domain Name.
For example, the contact with the email address "email@example.com" will be associated to the company with the Domain Name "testing.com".
With the setting toggle turned on, HubSpot will automatically generate a company record and feed it with information from HubSpot's database if the company record doesn't already exist in the there.
If the contact has a freemail email account like gmail.com, HubSpot will also look at the contact's Website URL property to attempt to match the contact with a company's domain name.
You can also opt-out a specific domain from this automatic association.
