Message tags are an optional feature that allow you to sort and organize your messages into custom folders. This is a great way to organize your messages by either topic, marketplace, or by ASIN/SKU.
You can access this feature from the Messages tab, within the "Edit Message" section of your message.
From here, enter in the name of your tag and click “Save”. If you have multiple tags you would like to enter for the message, you can separate each tag by using a comma. Click “Save” when you are done. The new tag(s) will appear on the white sidebar, to the left within your Messages tab. A message can belong to multiple tags and you can rename a tag, or delete it at anytime. By clicking on the tag, you can view the message(s) that belong to each tag.
