The Content Templates include your standard content for Campaign Info and Terms and Conditions. These templates are campaign-type-specific and will be imported every time you create a campaign.
For example: When you create a Mission campaign, we will import your standard Campaign info text and your standard T&Cs from your Content Templates.
During the campaign creation you can edit the content for the specific campaign. But if you want to edit your templates that apply to all your campaigns, you do that from here.
