The interface of storyport's tool makes it very user friendly, not only as far as creating content goes but also in sending out newsletters too. I have nothing against their product or service at all - they've been extremely helpful every step along this process. As long as your business has someone who knows what he’s doing (like myself) then there shouldn't be anything wrong with using them unless something else comes up such as budget restrictions which isn't likely if you're willing to put some money down. If you are looking to use one place where everything about building offsite content could go together including designing layouts, writing copy, choosing images etc., this should definitely be considered. They allow me to create engaging material without having much knowledge outside of basic HTML editing skills.
