I'm stuck at 2 though. I don't see a trigger for "fill out form" with gotowebinar form there.
Since you're directing them to GTW - GTW should be sending down the registrants back to Marketo (if your integration is setup correctly), and will be changing that status for you automatically.
Additionally, should I do 1 as a nested email program? or is it better to just create another step in the smart campaign to send out the invite?
We never used nested email programs. Simply because field marketing will more than likely want to send this out more than once, in multiple waves (to additional users). Instead use a regular smart campaign and include defined wait steps to send out confirmation emails, reminder emails and post-event emails - all within a single smart campaign.
Confirming that everything Dan said is accurate. Also wanted to remind you that you can manage the webinar registration process with a MKTO form and LP with this integration. As long as the webinar program is synced with the GTW event, program status changing will push people into GTW.
Person fills MKTO form on a landing page you created in MKTO. Change program status to Webinar > Registered.
This scenario will automatically push the record and mapped information into GTW as a registrant so you can really chose how much or how little of this process you want to customize or manage. Even down to choosing between automating your thanks for attending or sorry we missed you emails from MKTO vs GTW.
I like this process more than using the GTW registration form becasue its easier to manage/customize to your needs and you get all the normal functionality, like "Filled Out Form" triggers and whatnot.
I agree. The first thing I do when I schedule the event in G2W is to shut off all of the communication emails, because I want to send all of the communications from Marketo to control the styling and tracking. I also set up a registration landing page and confirmation page. One thing that I do different form Dan is that I use separate smart campaigns. This is for two reasons; 1) It gives me better control of each step (because my marketing people keep changing their timing), 2) Wait steps in smart campaigns can mess up the priority in the job queue.
FYI, here is how I structure my webinar programs...
We actually do the same thing - almost (and use On24, not GTW). Primarily, we use Marketo LPs for registration/confirmation pages. But we've started to use On24's confirmation email - which uses a branded template - due to some of the issues that some have experienced. Specifically in the unique link not being sent in time (or not at all) to be included in the confirmation email. We're also using On24's reminder emails (which are also branded properly) just to cut down on the number of assets (and chance for error) on the Marketo side. Finally, we also use multiple smart campaigns (vs. a single smart campaign with multiple sends/wait steps) to reduce potential error/risk.
