Hi team,                                                                               

Keap is a beast in itself in which you can do things effectively provided that you use it effectively, and know your way around it. We used Keap for managing our Contacts, sending promotional emails, marketing automation, and e-comm. Keap became much easier to use as we got to know the right ways of doing things starting from tag naming conventions, right ways of using Goals, Campaign links etc. And, now it is one of my favorite software when it comes to Marketing Automation.
