Marketing Calendar allows you to track the traffic data for your campaigns directly from your Google Analytics account, and share this data with your collaborators that have access to that calendar.

The statement is true. Semrush's Marketing Calendar integrates with Google Analytics, allowing users to connect their GA accounts and directly pull traffic data for their campaigns into the calendar. This feature centralizes performance tracking within the calendar interface. Furthermore, this data, once integrated, can be viewed and analyzed by all collaborators who have access to that specific Marketing Calendar, facilitating shared understanding and decision-making within a team.
