MessageDesk is a web-based business text messaging and shared SMS inbox platform that enables organizations to send and receive SMS/MMS from existing landline or VoIP phone numbers through a multi-user interface. MessageDesk is designed for mid-sized and larger teams that want a centralized way to handle texting without moving their primary phone numbers to a new carrier. MessageDesk supports U.S. and Canadian 10-digit numbers and can connect with all major VoIP providers and messaging services like Twilio, while allowing voice calls to remain with the current provider. Capabilities include: Text-enabling existing numbers: connect a business landline, Twilio, or VoIP number via number hosting/authorization, or use new local or toll-free numbers. Shared team inbox: all inbound/outbound conversations appear in a single inbox for multiple agents, with conversation history visible to the team. Relay automations/workflows: assignment, labeling, filtering, and internal collaboration features to automatically send messages and route conversations across threads. Messaging features: group texting, mass/broadcast texting, MMS messaging/media, templates, and scheduled text messages. Customers use MessageDesk in a variety of ways, including for appointment reminders, customer support via text, sales or lead follow-ups, dispatch and logistics messaging, HR and company updates, service and delivery updates, and billing notifications. MessageDesk also includes carrier registration support for A2P 10DLC, which is required for all business texting use cases in the U.S. You can use MessageDesk via any device with a web browser or download the companion mobile apps for iOS or Android. MessageDesk integrates with Zapier to connect to CRMs, forms, and scheduling tools. More integrations are planned for the future.
