Frequently Asked Questions

Multichannel means offering multiple support channels separately. Omnichannel means those channels are unified—conversation history follows the customer across channels. Converge provides true omnichannel with shared context across WhatsApp, email, Instagram, and more.

Industry benchmarks: Live chat under 1 minute, email under 4 hours, social media under 1 hour. Top performers achieve under 30 seconds for chat. Converge's unified inbox helps teams respond faster by eliminating channel-switching delays.

A unified inbox consolidates messages from all channels (email, WhatsApp, Instagram, etc.) into one interface. Agents see all conversations in one place instead of switching between apps, dramatically improving response times and preventing missed messages.
