For science fiction short stories I get all notifications of new issues and stories via RSS. There are some sites like https://www.freesfonline.net/NewAdditions.html https://www.freesfonline.net/NewAdditions.html that posts new stories every month or so. There are always news sites in that list to get more entries for my RSS reader, so no need to ever search web/agents for more content.
