Elizabeth  Wairimu - PeerSpot reviewer
Digital Marketing Manager at Unilever Inc.
Content teams have gained control to deliver omnichannel marketing content efficiently
The best features Contentstack offers are easy customization, a flexible platform, great support from a customer success manager, and an extensive app marketplace. Additionally, content update, content omnichannel delivery, content modeling, and an intuitive interface that is very easy to use stand out. The flexibility and app marketplace of Contentstack help a lot in communicating with our customers, allowing the business team to create and change content according to market strategy. Contentstack has positively impacted my organization because since we started using this tool, we have seen improved website response time by 50 percent. There is a great cost benefit, and Contentstack allows us to tell marketing stories effectively and efficiently. Contentstack APIs have allowed us to connect many other business critical apps easily. The impact on my marketing stories and efficiency is notable; I can execute campaigns very easily and we were able to reach out to many customers easily.
