A content calendar is a must-have for any marketing or comms teams that create and publish regularly. A collaborative calendar serves as a space for the entire team to come together to plan content, assign work, and see how their brand is going to market.
Since a collaborative content calendar is one of the core features of the Opal marketing platform, we know a lot about them. We’re putting together a guide to the features and functionality of calendars and exploring how the most popular choices stack up across the must-have features.
How We’re Evaluating These Tools
We’re going to be grading the most common choices to help you find the right calendar for your needs. For our list we are looking at tools that include a calendar as part of a larger suite of Martech features as well as standalone calendars.
