Duplicating a campaign allows you to clone a campaign along with the exact the same sequence and message for a different set of leads.
To duplicate a campaign, click on the show more button indicated by the three dots and select Duplicate from the drop-down menu. This will open the campaign editor.
If you're duplicating a Search on Linkedin campaign, you'll be able to update the audience. For all other types of campaigns, you'll be able to update the sequence, messaging, and campaign name. Publish to activate the campaign.
Unpublished campaigns will be saved in Drafts.
