What Does the Messages Module Gain You?

  The Messages module is a feature that allows you to contact the seller on your e-commerce site. This module appears on the page containing the detailed information of the relevant product or advertisement. A space is opened for the message you will send to the seller via the Ask a question to the seller button. The message you send from this section will be sent to the seller's page as a notification. If you are using the messages module for the marketplace site, you can access all messages between the seller and the buyers via the admin panel.

It works with the Notifications module.
