I love that they have built out some of my favorite features like social sharing, email drip campaigns with content upgrades for people who click through to your website from their emails! They also offer A/B testing which has been very helpful in our SEO efforts as well (we're not using it solely because we can't afford enough traffic!). We've recently started focusing more heavily into lead generation so this tool really helps us track data about what's working best when trying different approaches at generating leads online vs offline channels such as print ads or other paid advertising platforms etc..
