help regarding private messages and reaching out a creator

[Maxchaos]

hello
I really loved one of the webteases named lauren's game by kyrieelleison14. I sort of wanted to get in touch in with him. I sent him 3 PMs. I am little uncertain if those messages reached him. He has been online ever since I sent those messages but no response from him. That is why I don't know if those message reached him or not. They are currently in the outbox section.
Can you please provide me with some clarity about the situation? It will be really helpful.

Messages are in Outbox until they are opened by recipient (then they disappear from there, will be in sent)

If they're anything like me, they might not sign in every time they come to the site. I use private browsing most of the time so I don't stay logged in automatically and mostly don't bother unless I actually want to post something. Just be patient
