I've been curious what other professionals use as far as marketing calendars to create awareness/action-items of campaigns across different channels (social, email, magazine, print, etc). The main benefit would be to align the teams in a single apartment and beyond with marketing campaigns so they are not only aware, but can also coordinate action-items to help support.

Excel spreadsheets on internal servers and Google docs are used now to some extent. I've also heard from some that they use Trello and the boards/calendar they offer.

Any tools that others have experienced and really benefit from? Pros/cons?

Thanks in advance!
