With GDPR we will like ability to update subscription preferences for an account with your import tool because today it iis not possible.
And then when an email is sent to an account then visits or forms published will be attached to the contact who has the same email address (Primary Contact for example). For example, if this account updates its subscription preferences via a CD form, preferences will be updated at the contact level and not the account. Problem.
Being forced to create a contact to create subscription preferences for an account is not logical. The process becomes tedious.
