Unfortunately iVoox does not have a redirect tool, so we suggest you contact them through the following page: https://ivoox.zendesk.com/hc/es-es/requests/new

Here is an email template that you can use:

Hi iVoox Support, 

I'm moving my podcast to a new host provider and kindly request that you apply a redirect for the following show (Insert Your iVoox Feed Here)

Can you please apply a 301 redirect to my new RSS.com feed at (insert your RSS feed here, for example: https://media.rss.com/myRSSfeed/feed.xml)

Please let me know if you need any more information

Thanks in advance.
