You can customize email templates to send to each Registrant thanking them for registering and requesting they Boost your Event by sharing within their networks. Within this email, you are able to customize the From Name (sender name) based on your company. This should increase trust in promotors to share events within their social platforms.
As a default, Boost will automatically display the name of the company that is hosting the event. You are able to customize this in the email template step of Boosting your Event. If there is no company name provided, it will be prefilled with "Boost".
