Marketo webinar confirmation email doesn't allow me to simply provide an "Add to Calendar" link for registrants like WebEx email. I'd like to have WebEx send that particular email. I enabled that in WebEx and turned off Marketo from sending the email. But I didn't get the WebEx email even thought the registrant's info is captured in WebEx and Marketo.
I believe you will find your answer here: Sending WebEx Registration Confirmation Emails as Opposed to Using Marketo Emails
