Campaigns are critical objects in Plannuh. Using the Campaign object, you can bring together related, cross-functional marketing activities in support of a specific objective. Examples of campaigns might include hosting a customer seminar, attending a key trade show, running a digital awareness campaign, executing a TV advertising campaign, and so on. Anything that requires the coordination of multiple marketing activities AND has a measurable outcome should be treated as a Campaign.
Campaigns should generally be assigned to Goals: if you're spending a lot of money on a Campaign and it's not in support of a Goal, it may make sense to consider whether it's a good investment, or to assess whether you have defined all the right Goals and Metrics.
