Client ROI: Promptly responding to sales inquiries and nurturing leads in the DMs can directly boost your client's revenue.
Brand Reputation: A quick, professional, and helpful response to a customer service query enhances the brand's reputation.

Multi-Account Management: The ability to seamlessly switch between client accounts from a single dashboard is non-negotiable.
Team Collaboration Features: Look for tools that allow multiple team members to collaborate, assign conversations, and leave internal notes.
Robust Automation: Features like auto-replies, automated welcome messages, and comment-to-DM automation are essential for managing high volumes.
Bulk Messaging: The ability to send personalized bulk DMs is crucial for client campaigns and announcements.
CRM & Organizational Tools: Features like conversation labels, filters, and follow-up reminders are vital for keeping the inbox organized.
Security and Reliability: The tool should be secure and reliable, especially when handling sensitive client and customer data.
