MessageDesk vs. Missive

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.

Are you double sending emails? Not knowing who's responding to what, or whether they've responded at all? Losing the thread when the person who owns it is out? What if your business could manage all your email accounts, including its shared inboxes like support@, sales@, info@, and accounting@, along with SMS, WhatsApp, Messenger, and Instagram—all in one place? Missive is inbox collaboration for teams that run on email. Every conversation gets an owner, so nobody replies twice and nothing sits unread for a week.
