I would like to know if I can say "We can meet on Monday or Tuesday" in email as a reply to a sales person's email asking for a couple of days options for an online meeting -- a sort of Skype call. I am asking if the word meet is appropriate here and I welcome suggestions for a better reply to this email.
It depends on who you're talking to. Between friends, it's okay to use meet. At work, meet will be understood but will sound informal. I agree with previous comments. You can just use video/online meeting/conference, Skype meeting, etc.
I attend English class via Skype and we use: "Let's meet tomorrow" or "Are you available to Skype tomorrow?" These sound really informal. Just use what is appropriate for the situation and the person you are talking to.
