Question about RSS feed

Hi,

I am trying to use MailChimp to send out emails to subscribers whenever I post a new blog. I’ve verified the feed to be good (http://angles.co.nz/feed) but no emails are being sent. So before I look into the MailChimp end of things I just want top make sure I’m using the correct RSS URL? Or should it be …/wp-rss2.php?

The latest blog post is always displayed on the homepage using the blog element in the avia builder. Not sure if this is affecting things..

Thanks for the help!

Josh
