How are HubSpot emails validated?


#1

I would like to know since the email field in the system I work with isn’t mandatory, and can be anything. filter_var($email, FILTER_VALIDATE_EMAIL); does not validate as much as HubSpot does. This is preventing me from sending customer data from our database to HubSpot.

Any assistance would be appreciated.
