All campaigns are listed on the relevant campaign menus, in a grid or list view. The Drafts are sorted by the create date, Scheduled are sorted by the time of send, and Sent campaigns are sorted by the sent dates.
A calendar view is located on the dashboard for an easy view of campaigns. Campaigns that have been sent or are scheduled are shown here. From here you can view the campaigns details, and if they are scheduled campaigns you can edit or remove the schedule.
Tick on an individual campaign name to see more details. Additionally tick on the 'x more' option to view the list of all campaigns scheduled and/or sent for that day.
