Shortwave vs. Trengo

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.
