Shortwave vs. Missive

Shortwave is the smartest email app on planet Earth. Email is the backbone of modern business communications. Every day, billions of emails are exchanged inside and between businesses discussing everything from investment decisions, to high-stakes negotiations, to product designs, to major purchases. Email is the one tool that connects everyone — employees, customers, vendors, even the CEO. The biggest decisions are made in the email inboxes of business leaders. And yet, the inbox you rely on every day has not fundamentally improved in over a decade.

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.
