Sync Simplecast, or move it
Keep Simplecast if Basic or Essential fits the download curve and you expect to need Professional’s ad tools later. Point Beamly at the RSS feed and build the site, the blog and the member pages without giving up the host. Simplecast’s stats stay in Simplecast. Beamly will not recreate them for a feed it does not host.
You can keep public hosting on Simplecast and upload premium episodes separately to Beamly Creator. Move the public feed only if you also want Beamly to manage those files or remove the download-based hosting bill. Export reports first, since feed redirects do not transfer analytics history or paid access.
