If a label design is no longer needed, you can remove it from your account. Deleting a label removes the design itself — it doesn’t touch the underlying product data in your Data Manager, so nothing else is affected.
Only remove a label once you’re sure you won’t need it again. If several people share access to your account, it’s worth checking with them first — a design in regular use by someone else is easy to delete by mistake.
If you delete something you didn’t mean to, contact support and we’ll see what we can recover.
