Which of the following is a characteristic of effective CRM systems?

Integration of multiple communication channels is a key characteristic of effective CRM systems. This integration allows businesses to engage with customers through various platforms, such as email, social media, phone, and chat, ensuring a seamless and cohesive customer experience. By utilizing multiple communication channels, organizations can meet customers where they are most comfortable, fostering stronger relationships and improving customer satisfaction.

Furthermore, this integrated approach enables businesses to gather comprehensive data about customer interactions across all channels, allowing for better analysis and personalized marketing efforts. It also supports collaboration among different departments, such as sales and customer service, enhancing the overall efficiency of customer relationship management.

The other options do not align with the principles of effective CRM. Limited customer interaction would hinder relationship-building efforts, focusing only on sales data ignores the importance of customer service and engagement, and the use of outdated technology can severely limit the capabilities and effectiveness of a CRM system.
