We are unable to track submissions that are not made through Coverfly. However, if you place in a competition that is listed on Coverfly, we will import all placements, even of those who are not on our platform.
When we import placements, we do our best to sync the data for projects that exist in Coverfly. If a placement does not sync automatically, or you are new to Coverfly and don't already have that project on our platform, you can claim a placement here: https://writers.coverfly.com/claim-placement/all.
