Gmail add-on for Slack

Send emails into Slack channels and direct messages (DMs) directly from your email inbox with the Gmail add-on for Slack

You can install the add-on from these devices:

  • Any computer
  • iPhone
  • Android phones and tablets

Note: Guests in a workspace can only use the Gmail add-on if they have access to Gmail through your company's G Suite for Business account.

 

Step 1: Install the Slack add-on to Gmail

  1. Head to the Slack for Gmail page in the G Suite Marketplace.
  2. Click Add to Slack and follow the prompts.
  3. Click Done.

Tip: If you aren't able to install the add-on, ask a G Suite administrator at your company to whitelist Slack for Gmail from the G Suite Admin Console.

 

Step 2: Connect Gmail to your Slack account

After you install the add-on, connect your Gmail account to a Slack workspace. If you're a part of an Enterprise Grid org, you can connect any workspaces you're a member of.
