You can technically do this, however, I recommend using Excel or a project tool instead.
(TLDR: Only use for Marketing Ops Team snapshot into planned/past campaigns, not as the planning tool for the whole Marketing team)
Hi Suzanne, the Marketing Calendar is a nice glance at Marketing initiatives executed in Marketo, but falls short for team task management. I'd suggest an separate project management tool unless your entire Marketing organization have licenses and is using the Marketing calendar. Excel and/or a shared Google Calendar are manual, but effective, ways for your Marketing team to stay on top of their various initiatives and avoid things like communication overlap.
