Easy to implement and integrate with our other platforms like Salesforce Marketing Cloud or Office365.Easy to configure and maintain as it integrates well in the platform.The support team always have an answer quickly when i need them, even if its at 3am during US work hours! Nothing specific but overall service provided by their staff has been great so far. If they improve the UI design, better customer satisfaction. I would suggest everyone try out this product. We are solving all my marketing needs such as lead management, personalization, etc using MRB.
