eBay Standard Envelope is a Metered Mail shipping method and the tracking can only be read by the sorting equipment. You can't look it up on the USPS site like regular tracking you have to use this tracking tool> https://www.trackmyshipment.co/
If a buyer files a not received refund request then you can file an insurance claim to get your money back. See this link>
For future shipments I recommend dropping your envelopes in the metered mail box at your post office.
You can also review this post by a fellow Mentor that has screenshots of proper packing as the envelope must remain flexible enough to easily bend around standard coffee mug to be read by the sorting equipment. The example is for coins but the same rule applies for post cards and trading cards. A high volume card seller said that he uses a few sheets of standard printer paper around the card to protect it.
