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.
Anchor does not have a user interface from which to setup a 301 redirect. Therefore, to migrate your feed, use the 'Contact Us' button at the top of their help center to let them know you'd like a 301 redirect setup from your Anchor RSS feed to your Megaphone RSS feed. You'll also need the email address tied to your Anchor account.
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 before sending the URL to Anchor (you can test by opening the feed in a new tab).
