Our client, an online school, faced several challenges in effectively engaging their clients. Despite having a substantial client base of 7000 users, only 8% of them received calls, leading to missed opportunities for communication. Additionally, less than 50% of clients initiated their courses on the platform, indicating a need to improve user onboarding and engagement. Another significant hurdle was the high cost of the VoIP carrier service, which was impacting their budget and profitability.
