" I have read that the non-delivered rate is increasing."
Where have you read this? Have you had parcels go missing?
I have a registered business name but I only put my or my partner's personal name on all our parcels. Some of my Canadian suppliers who are large businesses also put a personal name on all their shipments.
Your business name and branding can be on your packaging INSIDE the envelope, instead of outside, where it will bring attention.
Make sure you package your items so it isn't obvious that there's jewellery inside. I use strips of corrugated cardboard inside a bubble envelope. When I have used small jewellery boxes, I wedged styrofoam the same thickness on either side of the box, so if someone was holding my envelope it was not obviously a tiny jewellery box.
When you are writing the customs form, don't use the word "jewellery". Write "fashion accessory". We usually write "metal ornament" or "steel ornament".
How expensive is your jewellery?
Either use 3rd party insurance like Insure Post or "self insure" which is adding a small amount to your shipping cost for each item. This is money that you save to pay out the rare missing parcel. Add 50cent to $2, whatever you believe you will need in X number of transactions to cover the rare occurrence of shipments not arriving.
So far I have only had to replace one order (it was two items). There was an exchange/return that did not come back from Afghanistan, so that was a loss.
Recently I did have a customer in Germany whose order was very late. At week 8 I had sent a replacement, 2 weeks later he received the original order. When he received the 2nd shipment (at 5 weeks), he paid me for it.
A few times the customer gave me the wrong address or I wrote it wrong, those orders all came back return to sender. Of course if something is delivered to the wrong address, it may not come back, again that is rare.
Yes there are some dishonest buyers out there, and problems with the postal system, theft and misdelivery can occur. But these should be rare if you do follow these tips to minimize your risk. Unfortunately tracking is not worth paying for unless you are shipping expensive items.
There are sellers that drive across the border on a regular basis to ship by USPS, because delivery confirmation is inexpensive and shipping is fast. This has the added cost of time, gas, a commercial fee for crossing the border, and renting a US mailbox (for the return address on the shipments). Only worth it if you have a high enough volume of orders and the time to do it.
