Dear Miss Snark,
You recommend USPS Priority + Delivery Confirmation for sending out requested manuscripts, but I think it's bum advice because I just did exactly that and my pages arrived on Saturday when the agency was closed, so a notice was left for them to either pick up my manuscript at the post office or call the post for redelivery. How inconvenient and off-putting is that! Maybe that's what assistants are for, but I don't think assistants appreciate the extra Monday morning hassle either.
Well, I'm surprised there was mail delivery to an office on Saturday here in NYC. Most offices have the mail held over till Monday.
My experience has been that the mail carrier scans the bar code and leaves the envelope on a delivery confirmation. I've never had to trek to the post office to get one.
Don't confuse confirmation with certified mail. Two entirely different things.
And if in fact the mail is at the PO chances are the agent will NOT go get it. I never do.
And I didn't recommend it at all. The wording was "if you really absolutely have to spend more than a first class stamp, use delivery confirmation". I think priority mail is a total waste of money.
