I always mail books using PayPal or USPS Shipping Assistant and have a USPS delivery confirmation number. 

I check to see that books have been delivered after 10 days if they've not been marked received.

A book I mailed Oct. 6, it was delivered Oct. 12.

The person receiving the book has NOT marked it received yet.

Is it permissable/advisable to send a PM requesting that s/he mark it received? 

What do you do?  Thanks, Katie

Yes, it is permissable to send a PM. I have done this a couple of times and the receiver thanked me for the PM because they forgot to mark it received.

I would have PMed about a week after the scan showed delivered in an attempt to catch a mis-delivered package while the carrier still remembered it. I would definitely PM now, but  almost 6 weeks after, the person and the carrier might not remember anything.

Another senior moment -- the dates were Nov. 6 and Nov. 12 not October.  Sorry.  Thank you for your input.

I had the same thing happen to me about a week ago.  I sent them a PM, and they PMed back saying they were on vacation -- they marked it received about a week later.  I had DC that showed it was already received, but I just wanted to get the book off of my main account page.

Keep in mind that while your DC says it has been delivered that Does Not mean it was delivered to the correct address, so rather than PM to ask them to mark it received I'd PM to confirm they had received it...don't make any assumptions about them actually getting it.

:) I kind of wondered that. I think the timing is perfect for a PM. As Christy says, I wouldn't word it as "I can see you've received the book so mark it mailed" because that can make the receiver feel accused. I usually PM something like "The Deliver Confirmation shows the book scanned as delivered last week on the 12th.  Could you please double check and confirm whether the book was delivered to you? The more quickly I file the paperwork to start the USPS tracking a misdelivered book, the more likely the carriers and clerks are to remember what they did with it." Everytime I have sent a PM like that the book was there, sometimes misrouted, but was always found and marked mailed.

Yes, I recently sent a PM stating:
 

"Hi ____,

Have you receive the book, __________________?

According to the USPS Delivery Confirmation you should have received the book on Oct 20th.

10/20/2009 1:56 PM - Delivered - GAINESVILLE,FL

If you have not,  check with the P.O. to see if they are holding the book for you, or if it was accidentally delivered to the wrong address."

It comes off as being helpful rather than accusatory that they are lazy, etc. As it turned out in my case, she was away and her DH was putting all her packages off in a pile. She marked it Received when she got back a couple days later.

Nice examples of pm's for the situation Melanie & Eve.  Starting with the helpful approach gets communication off to a good start :-)

Katie, I'll agree that the timing is about right for follow up contact.  Some post offices incorrectly scan packages as 'delivered' (to the addressee) instead of the correct 'arrived at unit' (the local PO).  In this case, actual delivery can take a couple more days.  Hope the book shows up!
