I have been using this system to distribute articles from my blog as well other sites that are relevant in our niche area (healthcare).
It's very easy use once you get used it! The only thing is sometimes when i'm sending out multiple emails at one time they will not all go through but if send them individually after about 10 minutes or so then everything goes fine again - no big deal though just be patient with how long some take before going thru!! Great product overall great customer service too. We've had nothing bad experience yet we're working together since 2009 till now still happy customers :).
