Omnichannel differs from multichannel (which offers multiple channels in silos). In an omnichannel setup, an agent can see a customer's WhatsApp message, previous email thread, and phone call notes in a single view. This eliminates the need for customers to repeat information.
InboxCentral is an omnichannel platform that unifies WhatsApp, Instagram, Facebook Messenger, Email, SMS, Push, and Voice into a single inbox with shared conversation history.
