Reach out to [email protected] to get a custom feed URL for your newsfeed. You'll receive a DNS record that you have to install under your domain.
The custom URL will have to be a sub domain e.g. newsfeed.yourwebsite.com. It's possible to have multiple feeds on the same URL. Let us know before requesting the domain if you plan to use the domain for multiple newsfeeds.
After you have received the DNS record, log into your domain provider, look for "DNS settings" and create a new DNS record of type CNAME. Insert the host and value keys and click Save.
The changes can take up to 24 hours to populate. Contact [email protected] to verify that your new custom feed URL works.
Your old newsfeed URL will redirect people after your new URL has been verified, so there won't be any breaking changes for your contacts that might have received any posts already before the domain was changed.
