    Re the Signature Proof of Delivery above:

    Where is the option for the FREE (not "Adult") signature confirmation for Priority Express Mail?  The USPS offers that option for free, but Shipping Express does not???

    So we either get no signature, or have to pay $4.95 for the Adult signature?

    What's up with THAT?

    What is the fastest service from the United States Post Office that will put mail in my mail box WITHOUT getting a signature from me? I cannot spend all day at home just waiting for the mailman to show up. If he won't leave it without a signature, I need another option.

    Hi Ted,

    You can add a signature confirmation option to your packages. For some carrier and package selections, this is free, and others there is a small fee, and for some, this option is not available at all. You can select this option on the Ready to Ship page, if available, for your selections.

    There is more information on this article here: https://support.shippingeasy.com/hc/en-us/articles/203084269-When-selecting-a-USPS-service-for-a-shipment-what-do-the-different-delivery-confirmations-mean-

    If you do not want a signature option to be required, just make sure you do not select this option when you make your shipment so it will not be required when your package is delivered.

    Warm regards,
    Taylor Painter
