Every get that statement? I have on several occasions yet my personal server log shows it was delivered and the e-mail wasn’t kicked back. Well here is a nice service.
“Have you ever needed to know when the email you sent has been opened and read ? How many times it has been read ? Would you also like to be notified by SMS the instant your ‘sent’ email is being opened ? Well, now you can. This service is provided free of charge by Fallencrew Associates. What’s even better is the recipient will not even know of the tracking”.
I have heard that the service may even have some extra features but you need to check out there website to get the full details.
