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
- Head to the Slack for Gmail page in the G Suite Marketplace.
- Click Add to Slack and follow the prompts.
- 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.
