After creating a segment, you may want to iterate on it down the line without changing the conditions of the original segment. You can do this by cloning your original segment. You can then add or change conditions within the new, cloned segment.
For example, if you have a segment of recent purchasers and you'd like to create a related segment of recent purchasers who also made at least two purchases in that period, cloning the initial segment will save you time instead of setting up the same conditions for recent purchasers.
How to Clone a Segment
To clone a segment, click into the segment of your choice. Then, select Manage Segment > Clone Segment.
You will be brought to your duplicate segment's definition menu, where you can add or delete conditions. Make sure you give your duplicate segment a unique name to avoid confusing it with the original.
Once you have edited the segment to your liking, select Clone Segment. You will then see both the original and the cloned segments within your Lists and Segments tab.
