How to create an email+Slack hybrid group

Updated 3 years ago by Floriane

If you're starting a new project with an external consultant or you work on a team where most of your teammates are mostly in Slack with the exception of a few people, then try out our hybrid email+Slack groups. 

These groups work much like an email list or a Google Group, where members can be added and removed as the project or team changes. But the rules are the same: emails and Slack messages are sent to the entire group, every time.

Here's how to create an email+Slack hybrid group:

  1. Add MailClark to Slack if you haven't done it yet. 
  2. Go to and click "Connect a new account".
  3. You’ll be asked to select a Use case: Choose Email Guest. 
  4. Choose the channel you'd like to connect with the Email group.
  5. Set up the email address dedicated to the group.
    In the "Guests’ email addresses" box, enter the email addresses of those you want to communicate with.
    (We suggest you to start with just you as a member in order to send the test. Then add the rest of the email group members after the test goes through.)
  6. Hit "Continue" and go back to Slack.
    Back in your channel, every new message posted will be automatically sent out to your "Guests" and, conversely, the emails they send to the channel are posted in this channel.
    If you are afraid of sending out a message by mistake, you can deactivate auto-send.  
    @mailclark pause into the channel to pause auto send, and  @mailclark start to resume it.
  7. You can add/remove guests anytime from your settings page
