#Duosoma and #Duotrope are a submission tracker and portal. Authors can upload submissions to open markets free. If the market has a box to be checked, they can track those submissions to be reported in Duosoma's numbers. https://duotrope.com/duosuma/submit/opportunities/ The currently open submission opportunities page was recently updated. It now gives a title, and a line of information about the market. The calendar view can be useful.

Submittable is a submission portal mostly used by the drabble and fiction markets I follow. though there are a few other genres as well.
