Gmail Integration

Route support emails from Gmail into ReplyMill and Slack.

Overview

ReplyMill connects to Gmail through email forwarding. You set up your Gmail account to forward incoming support emails to your unique ReplyMill address. No OAuth tokens, no API keys — just simple forwarding.

Setup Instructions

Step 1: Get your ReplyMill forwarding address

After creating your company in ReplyMill, you'll receive a unique forwarding address (e.g. yourcompany@in.replymill.com). You can find this in Settings → Integrations → Email.

Step 2: Configure Gmail forwarding

  1. Open Gmail Settings (gear icon → "See all settings")
  2. Go to the Forwarding and POP/IMAP tab
  3. Click "Add a forwarding address"
  4. Enter your ReplyMill forwarding address and click Next
  5. Gmail will send a verification email — ReplyMill will automatically confirm it, or you can click the confirmation link manually
  6. Back in Gmail Settings, select "Forward a copy of incoming mail to" and choose your ReplyMill address
  7. Choose "Keep Gmail's copy in the Inbox" (recommended) so you still have emails in Gmail as a backup
  8. Click Save Changes

Step 3: Verify it's working

Send a test email to your support address. Within a few seconds, you should see it appear in your ReplyMill dashboard and, if Slack is connected, in your Slack channel.

Using Gmail Filters (Optional)

If you only want to forward certain emails (e.g. emails to support@ but not billing@), you can use Gmail filters:

  1. In Gmail, click the search bar dropdown to open filter options
  2. Set your criteria (e.g. To: support@yourcompany.com)
  3. Click "Create filter"
  4. Check "Forward it to" and select your ReplyMill address
  5. Click "Create filter"

This gives you more control over which emails ReplyMill processes.

Google Workspace / G Suite

If you're using Google Workspace, the setup is the same. Your Workspace admin may need to allow forwarding in the Admin Console under Apps → Google Workspace → Gmail → End User Access.

Troubleshooting

Emails not arriving in ReplyMill

  • Check that forwarding is confirmed and active in Gmail Settings
  • Make sure you selected "Forward a copy" (not "Disable forwarding")
  • If using filters, verify the filter criteria matches the emails you're expecting
  • Check your ReplyMill dashboard — emails may take a few seconds to process

Duplicate emails

If you see duplicate threads, make sure you only have one forwarding rule active (not both a global forward and a filter forward to the same address).
