I am a long time seller and new to selling postcards. I sold several and shipped them safely USPS in a postcard mailer with a stamp. No problems except I marked them ship but didn't upload tracking since there was none. Anyways, I just got my sellers report and my Top Seller status was downgraded for lack of tracking on the postcards. What should I have done to verify they were shipped and is there anyway I can regain my top rated seller status since evrything else was good?
