Yes! FeedBolt is a great way to mail your members the latest content from your membership site.
We work great with WordPress based membership sites like iMember360, Memberium, WishList and more, Joomla based memberships sites like JoomFuse, as well as dedicated sites that have RSS feeds like CustomerHub.
You’ll want to make sure that the Feed URL you select allows for us to see the latest posts and not just the “public posts.”
