By default, form submissions to HubSpot require a populated email address field to create contacts. However, you can turn on the Allow submissions without email addresses to create contacts setting to allow visitors to submit a HubSpot form without an email address and still be added to your database.
Before you get started
Do take note of the following:
If you're using a non-HubSpot form, this setting does not apply. A populated email address field is still required to collect submissions, learn more about using non-HubSpot forms.
If you're using a custom email field and have this setting enabled, form submissions will create contacts. However, because the default HubSpot Email property has no value, these contacts cannot be emailed or be enrolled in workflows.
Contacts created via form submissions without an email address will deduplicate based on cookies. If two people with the same cookie fill out a form with no email address (e.g., if they were using the same device), both submissions will be associated with the same contact record. However, if the Always create contact for new email address option is enabled, each submission will create a new contact.
Allow form submissions without email addresses to create contacts
To turn on this setting:
In your HubSpot account, click the settingssettings icon in the main navigation bar.
In the left sidebar menu, navigate to Marketing > Forms.
Click the Submission Settings tab.
Click to toggle the Allow submissions without email addressesto create contacts switch on
