Sharing a direct room link for a webinar

Hello everyone, 

I am new to Zoom webinar. I was wondering if there is a way I can link up a direct room link to an email for people that have not registered yet for the event through Zoom. 

I have a registration page I created here: Claudia Audley July 22 Online Event | Omlet. They register through an embedded form and can add the event to their calendar but it doesn't have the Zoom link in it. You have to register again when I added the invitation link here to the thank you email once people register here: https://zoom.us/webinar/register/WN_885KZGQJSBO8uWLVTu7BCg

Any suggestions?
