I really liked that it was very easy to use once we got our content out into their system (which you can create from scratch or pull in an existing CMS like WP). It's also great when tracking conversions through your email campaigns with integrated analytics so there are no excuses not making sure things work as intended! A few minor issues here & There which they have been able fix quickly but all-in -all this product has done wonders at generating leads both new customers via SEO/SEM strategies plus bringing back old clients who had lapsed.
