Recently my boss received an email from me which I did not send out. The email is not those normal advertising gimmick, it's a private and personal conversation between and someone. After realising it, I went to check my sent message, but there isn't record to show that I sent out any email. I am afraid that this particular conversation will be sent out to other personnel in my contacts, thus I deleted all my messages and closed the account. However I do still feel uneasy about it as I do not know how many of my contacts had already received my email, is there a way to track?? pls advice.
