Examples of Smart Choices
These examples show how mailing services
can be combined to meet your needs.
Example 1: Sending a Valuable Item
Jane’s niece is getting married next month, and Jane wants to send a piece of heirloom jewelry to
the bride. The jewelry has a lot of sentimental value, so Jane wants to be sure that it will arrive safely.
Jane identifies three possible options:
$$$ Option A Express Mail
Express Mail automatically includes insurance up to $100 and guarantees delivery to Jane’s niece
in 1 to 2 days. Additional insurance may be purchased. Jane will also receive a mailing receipt and
confirmation that the package has been delivered and has been signed for by her niece.
$$ Option B First-Class Mail Package with Registered Mail
First-Class Mail offers delivery at a low cost and can be combined with Registered Mail, a service
that provides the highest level of mail security during transit. Insurance can be purchased for items
up to $25,000 in material, but not sentimental, value.
$ Option C First-Class Mail Package with Insurance
First-Class Mail offers delivery at a low cost and can be combined with insurance for up to $5,000.
Insured Mail will cover the jewelry’s material value should the piece get lost or damaged, but it
cannot cover its sentimental value.
Jane decides that speed is less of a priority than security. Jane chooses
First-Class Mail, and, because the jewelry has greater sentimental than monetary
value, she decides to add Registered Mail service so she can feel confident
that her heirloom will be as secure as possible during transit.
Example 2: Sending an Important Document
Maria recently sold her car and needs to transfer the title to the new owner. Maria wants to be certain that
the new owner gets the title to complete the sale. Maria considers these options:
Option A Express Mail $$$
Express Mail will arrive at many locations the day after it is mailed. Express Mail also provides
Maria with proof that she mailed the title, the ability to track it online or by phone, and notification
that it was delivered. Maria can also request a copy of the recipient’s signature.
Option B Priority Mail with Confirmation Service $$
Priority Mail will get the title to its destination in 1-5 days. Maria could add Delivery Confirmation,
which lets her obtain delivery information online or by phone. If Maria uses Signature Confirmation
she gets the same delivery information, plus she can request a copy of the recipient’s signature.
Option C First-Class Mail with Certified Mail and Return Receipt $
First-Class Mail will get the title to its destination in 1 to 5 days. Certified Mail with Return Receipt
will give Maria proof that she mailed the title and will return a card to her with the date the title was
delivered and the signature of the person who received it.
Maria wants a copy of the signature returned to her to prove that the title was delivered,
and she wants to get the lowest price she can. Maria decides that First-Class Mail with
Certified Mail and Return Receipt is the best option.
