The only difference between campaigns and campaign templates is in how you save the record. You can add planning tasks, campaign activities, marketing lists, sales literature, and products to both campaigns and campaign templates. Use a campaign to plan and track each of your marketing campaigns. Use campaign templates to create reusable groups of planning tasks and campaign activities for similar or recurring marketing campaigns.
Because campaigns serve as containers for the various items you can include in them, there is no need to close a campaign once all of the planning tasks and campaign activities have been completed.
