How to open a chat, send messages, and keep the conversation in one place. All deal-related messaging stays inside mmmyep so both sides have a clear record.
Chat is available as soon as a buyer taps I'm interested on a match. We create an engagement linking that buyer’s search to your listing (or vice versa if you’re the buyer). Both sides can open the chat from their dashboard: Buyers go to the Engaged tab and click Open chat on the engagement; sellers go to Interested Buyers and click Open chat. You’ll land on the engagement page with the chat thread and deal status.

Buyer: Engaged tab → Open chat. Seller: Interested Buyers → Open chat.
The chat appears on the engagement page, below the vehicle summary and deal status. Your messages appear on the right (in a primary-colored bubble), the other party’s on the left. Type in the box at the bottom and click Send or press Enter. Messages are delivered in real time — no refresh needed. You can send images if you’re sharing documents or photos. Read receipts show when the other side has seen your message. Keep all negotiation and agreements in the app so there’s a clear record if you need support later.

Your messages on the right; their messages on the left. Type and press Send or Enter.
When the first message is sent, the engagement status changes from interested to chat_open. As you negotiate, one of you can update the status to price agreed when you’ve both agreed on a number. Then finalizing (inspection, Bill of Sale, payment) and finally completed. Updating status helps you and mmmyep track where the deal is. Direct phone and email for the other party are shown in finalizing or completed, not at price agreed — keep negotiation in chat until then. See Partners, data & trust. If either side needs to back out before price agreed, the buyer can withdraw the engagement. After price agreed, backing out without a valid reason can affect ratings and deposit; see Ratings and Trust & Safety.
