Hello community, how are y’all doing?  
Is it possible to block the new contact creation by invalid email input at a form submission?

Hi [@Caio\_Felipe](https://community.hubspot.com/t5/user/viewprofilepage/user-id/345893),

HubSpot already does this to a certain extent. See here: [Forms | Frequently Asked Questions](https://knowledge.hubspot.com/forms/forms-faq#form-field-validation)

There will however be emails that won’t be valid but don’t necessarily get blocked by the points listed in the article. For example, a domain may not be blocked and be a valid email domain, but HubSpot wouldn’t necessarily stop this email from creating a contact if the info before the @ isn’t valid unless it has globally bounced in the past.
