In order to duplicate a campaign:
- Navigate to Campaigns>Campaigns> Specific campaign
- In the upper right hand corner, click on the duplicate button (in blue)
- If the campaign is in draft state, you will need to click on the vertical ellipses in order to access 'duplicate'
- The content of the campaign will be copied to the new campaign
- The date ranges etc. on step 3 will still need to be user defined as they've likely already passed
- Be sure and check each step of the campaign to make sure it is configured as you desire, before scheduling.
