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.
