The two actions that the Marketo Engage Architect should recommend to meet these requirements are to create a webinar email asset in the program template that uses Velocity Scripting to populate region and industry and to create a regional webinar program template with a consistent naming convention. These actions will help the Architect to quickly scale the volume of webinars from once a month for North America to three times a month globally, as well as to vary the content of assets for different combinations of region and industry. Creating a webinar email asset in the program template that uses Velocity Scripting to populate region and industry will enable the Architect to dynamically insert content based on the lead’s region and industry segmentation fields, instead of creating separate email assets for each segment. Creating a regional webinar program template with a consistent naming convention will enable the Architect to easily clone and customize the program for each region, as well as to report on the results of each webinar at the global and regional level.
