To deliver strong support on Facebook Messenger without losing the human touch, businesses should set up a welcome message that matches their brand's identity, be quick with responses to all inquiries, and use personalization by addressing customers by name. This can help establish a sense of continuity and build trust. Additionally, responding promptly to complaints and setting up resources to address them in a timely manner is crucial. Keeping customers informed about company news and updates also helps build trust and transparency. By adopting these strategies, businesses can provide effective customer service on Facebook Messenger while maintaining the human touch that makes customer service valuable.
