Add a personalized URL to multi-platform save the dates in emails?

[Julia_Campbell]

Hi folks,

We're using Zoom for our webinars, and it's currently integrated with Marketo. We send out personalized Zoom links to those who register for webinars using the token {{member.webinar url}}. This allows Zoom to recognize which registrants actually attend the event and sync the right Attendees back to the system post event automatically.

The {{member.webinar url}} token works well for the native MKTO .ics save the date and in the body of emails. We're hoping to expand our save the date functionality to be more like what AddEvent offers (e.g. add the event easily and to Apple, Google, Office 365, Outlook, Outlook.com, and Yahoo calendars). Their solution is user friendly and something our marketers could use easily to put together save the date links for various platforms and add to their email builds. For example, here's what their standard setup looks like in the body of an email:

The challenge is that MKTO doesn't support nested tokens, and my test with AddEvent to allow personalized URL's in save the dates is failing. I've tried in the location and description areas for events. For example, my test for a Google Calendar save the date appeared as follows when I clicked the AddEvent link from my test email. This wasn't unexpected due to MKTO's token nesting issues, but I'm hoping to find a workaround:

Is there a way to create save the dates for multiple platforms using a token to allow for personalized URL's to an event? Ideally with something user friendly (like AddEvent) that non-techie Marketers can use easily? If there's a way to do this with AddEvent, would love to know the workaround.

Thanks in advance for any insights!
