How to Send Emails from Slack?


In business, communication is essential to ensure all the departments and teams can synchronize with one another.

Slack is a well-known communication tool for workplaces. When it was launched, it hardly had any competitors. The biggest plus of Slack is that it combines a user-friendly interface with a group and one-to-one messaging. Moreover, it looks informal and is fun to use. Even non-technical users can use it without facing any difficulty.

When Slack hit the market, the aim was to do away with email. However, that never happened. Email is still alive and thriving, which means that Slack and email now have to coexist.

Let’s take a closer look at the Slack-email connection and how you can send and receive emails on Slack.

What makes Slack popular?

Slack is used widely to enable communication in the workplace. It carries out the following jobs,

  • It lets you communicate in the workplace.
  • It enables remotely located team members to communicate with each other.
  • You can share documents, images and other files across teams.

The reason for Slack’s popularity is that it has a bit more to offer than just the above,

  • It is a status symbol – If a company doesn’t use it, others think that it is not competent enough and is not doing well. Telling people that you are working with a firm that uses Slack is more of a status symbol.
  • You feel important and productive – You may feel busy and more productive when you write the minutes of a meeting on Slack. You won’t get such feelings when you write an email.

Slack is so commonplace now for workplace communication that most companies can’t do without it.

Can Slack and email work together?

Instead of making Slack and email compete with each other, it is better to let them complement each other. Both have their benefits, and when they are combined, it can be a win-win situation. For instance, Slack helps reduce the email count in inboxes, and email helps add more context to Slack channels and saves time.

Receiving emails on Slack is quite helpful as teams will get notifications in their Slack channels to carry on with discussions straightaway in the threads. One example of this is E-commerce platforms notifying about new orders placed or the status of the existing stocks directly in Slack.

Now that you know you can receive emails on Slack, can you send emails from Slack too? It is not only common to push emails into the Slack app, but also beneficial to send emails from it. For instance, if the person you want to contact is not on Slack, you would like to email them from within the app itself and also receive their replies right there. It is possible to do so using integrations. You can even bring the entire inbox into a Slack channel with the help of available integrations.
