It is critical to know if there are errors with your listings. When you have a listing you've put time into or you have a lot of inventory that isn't selling, you want to be aware of when and why that is happening. Often, your listing is only missing a photo or some minor information. Sometimes, there was a problem with a flat file feed, a typo, incorrect categorization, or something else that needs your attention. Get notified of these situations so you can take action.
