I'll ask about this with Presto's product team. Because Presto is not meant to be an instant fax delivery service, and because delivery times are also dependent on whether someone in the household is on the telephone at the scheduled call-in time, I don't know if this would provide a lot of value to the user.

I'd love to know what you think the real value of a timestamp would be to the Presto user, or the account manager. Please post your thoughts.

My mother who has a Printing Mailbox has frequently mentioned to me that she'd like to know when the messages were actually sent.  She knows that she only receives them 6 times per day, so the time received is unimportant to her, it's the time actually sent by the sender that's important to her.

 As an example, the last time they get sent to her each evening is 9pm.  When she gets her first messages in the morning, she often wonders how late at night the sender actually sent the messages to her.
