Note: There is no "one size fits all" redirect. Therefore, we recommend logging into Megaphone and contacting us via Live Chat to walk through the process together. Below are general guidelines.
Acast does not have a user interface from which to setup a 301 redirect. Therefore, to migrate your feed, email Acast at firstname.lastname@example.org asking them to setup a 301 redirect from your Acast RSS feed to your Megaphone RSS feed.
Use this article for information on how to find your RSS feed in Megaphone. Double check that the Megaphone feed is correct and working properly (you can test by opening the feed in a new tab).
