The co-founder of the workplace chat room app Slack referred to email as the "cockroach of the Internet" when asked about the longevity of email in the digital workplace, according to Business Insider.

"Email will be the cockroach of the Internet," said Stewart Butterfield Tuesday. "I think we've got another 30 or 40 years of email left."

Using Slack allows you to avoid the amount of emails that you receive from your colleagues and makes internal communication with your co-workers much more efficient.

"Email has many benefits, it's the lowest common denominator for official communications," said Butterfield. "But it's a terrible way to manage internal communications."

Slack was launched in 2013 and now has over one million active users daily, allowing the company to reach a value as high as $2.8 billion, according to CNET. It is currently competing with other collaborative business software such as Convo, Glip, Fleep and Cisco Spark.

The company has a growth plan for the forthcoming years and plans to add many new features and focus on new developments, according to the Australian.

"If someone offered us a hundred billion dollars tomorrow, we'd probably take it," said Butterfield. "On the other hand, we're growing really fast, I love the people I work with, our customers are super-happy. We work hard but we've also had unbelievably lucky timing — there are so many trends that we've caught at the top of the wave. We'll never have a chance like this again."
