Instant Messaging (IM) in CRM refers to real-time, text-based communication that enables businesses to engage with customers instantly via chat interfaces. IM functionality can be integrated into CRM platforms for customer support, sales assistance, and internal team collaboration. Many CRM systems use chatbots and AI-powered assistants to automate responses, route messages to the right department, and improve response efficiency. Instant messaging is commonly used for live chat on websites, mobile apps, and customer portals, allowing businesses to enhance customer experience and streamline service interactions.
