For example, my sales rep wants to be able to follow up with everyone that attended a particular webinar, and then clicked a follow up email. Creating this list in Marketo takes less than a minute, but we can't seem to figure out how reps can see this list in Salesforce. What's the best way to share lists with sales reps from Marketo to SF? Thanks for the help!
The very best way is to use campaigns and campaign statuses. You will be able to feed this from Marketo (either using "add to SFDC campaign" and "change SFDC campaign member status" flow steps or sync'ing a Marketo program). And in SFDC, you will be able to create campaign member reports to provide exactly the information you are looking for
