How long does a message remain in the inbox on Copains d'avant?

I believe it depends on your email service; in my opinion, this message stays in the recipient's inbox until they open it, and if they haven't read it, you can't know. Ask a friend to send you a message and don't read it; you'll see. However, someone sent me a message, and I didn't receive it, so they could have thought I didn't want to reply. What is the real meaning of your request?

Hello Sandrine, I sometimes experience the same thing. I sent a birthday card through the site a few weeks ago and I don't know if the person received it, especially since I recently noticed that this person was online at the same time as me on the site. As for emails and "hello," it's the same. I wanted to say "Hello" to someone I know, taking advantage of the fact that this person was online on the site. Unfortunately, I don't know if my message was received because I didn't get a response. So, what is happening? Was the message deleted without being read or is there a messaging problem? I don't know. Have a good day.
