We chose Webflow to build up websites faster and to make possible for particular employees to fix some misspellings or add an easy element to the page on their own - it is like Adobe Photoshop. To work with the incoming traffic we use our own product, that I can't pin here. It helps to make nurture visitors from the first session into the signing up and further activation into the product. In addition to @Carrrot we use Google Analytics to traffic source awareness, to monitor customers inside the product FullStory helps is a lot with its fury clicking and abandoned links. Activation and retention are done by our own product through the pop-ups, live chat, and emails that all based on customer behavior.
