You can use the existing campaign in another workspace without wasting time to create the same email copy by copy/import option and at the same time keep campaign details such as sequence (email copy), campaign schedule, and settings.
Here are the steps on how to copy and import the existing campaign from one to another workspace:
Get the campaign URL from the campaign you want to copy/import. Click on the "..." icon at the end of the campaign and select "Share campaign"
After clicking the share campaign, you are presented with two options: Copy link/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 your campaign right there in front of you
Congratulations, you've successfully imported your campaign🎉
