Send email from excel to outlook

Have a code that does this but never sure if it's sent without going to outlook.Is there a way to have message box popup in excel that mail was sent in outlook.Sometime it seems like stuff get hung up in the outbox,so if it not sent a error message.Not sure any of this is possible,maybe some links to examples would be helpful.I can post what I'm using now if needed.

Thanks for any suggestions.
