Is Slack better than email?

The inbox had its heyday, but work today demands more than the status quo. Like a whole new approach to productivity.

It’s not that email is broken—it’s limited

Even though landlines still work, we prefer to do everything on our smartphones. It’s not surprising. Better technology allows us to move faster, accomplish more and connect more easily. That’s exactly what Slack provides, while the inbox remains stuck in a cycle of refresh and reply.

“You can’t have a good conversation over email—it’s not quick enough. Coming together in Slack channels allows us to easily discuss day-to-day management topics. That’s invaluable.”

What Slack offers vs. email

Slack isn’t just a tool for sending messages. It’s a place where work flows between all your teams, tools, customers and partners—wherever and whenever you’re working.


All content in Slack channels is searchable, so there’s no need to forward a bunch of emails to the person joining your project.


File sharing, calls, clips and more are all built into Slack—along with real-time messaging. So you can truly work together however you work best.


Slack brings internal and external teams together across locations, time zones and working styles, instead of confining work to email’s siloed communication.


Collaborating in email opens up the risk of spam and phishing. In Slack Connect, you can work securely with partners, vendors or customers.


Connect over 2,600 apps to Slack—whether that’s your calendar or the tools you use every day—and never forget an attachment again.


In Slack you can turn routine meetings and tasks like standups, approvals and requests into automated workflows to save on the back-and-forth.
