Overview

Messages from your authenticated eBay account, including buyer questions and eBay's own account notifications, all land in one inbox next to the order they relate to. This needs an authenticated eBay connection.

  • Open Messaging Center in Keysender.
  • Filter by eBay account, or click a message to read the full thread.
  • Click the reply icon on a message, write your response, and click Send.

Before you start

Make sure you have:

  • Access to your Keysender vendor account.
  • An authenticated eBay connection in Keysender.

Frequently asked questions

Which messages can I manage in the Messaging Center?

The Messaging Center shows the eBay messages sent to your authenticated eBay account. You can read them, mark a message as read or important, or delete one you no longer need, all without switching to eBay to manage your buyer communication.

What do I need before I can reply to messages in Keysender?

You need access to your Keysender vendor account and an authenticated eBay connection. Once eBay is connected, the Messaging Center loads the messages sent to that account so you can open a thread, click Reply, and send your response.

Where does my reply go after I send it?

Your reply is sent through the eBay messaging system, and the buyer receives it in their eBay inbox. Open the message subject to see the full conversation thread, click Reply, write your response in the text box, and click Send.
