Rejection isn't the end — it's feedback. You'll get an email (and see it on My Listings) explaining exactly what to fix. Tap Edit & resubmit — it's free, and you get two free resubmissions per listing.
If a listing is rejected a third time, it can't be resubmitted, and the credits you spent on it aren't refunded. You'll get an email explaining why. If it was a fixable issue, you can create a fresh listing (a new fee applies). If the item is on our prohibited list, please don't relist it.
