You can import the existing campaign to another workspace without wasting time to create a new one. All campaign details, including the sequence (email copy), campaign schedule, and settings will all be copied, except for the leads.
Please check the steps on how to copy and import the existing campaign from one to another workspace:
Open the target campaign
Click on the "..." icon in the top right corner and select "Share campaign"
You are presented with two options: Copy Link or Export File.
Select "Copy link"
Paste your copied link into the web browser while logged in to your workspace.
Click on "Let's go" when prompted.
Once you've done that, you'll see the campaign right there in front of you.
Congratulations, you've successfully imported your campaign!
