How to Route Gmail Support Emails to Slack with Zapier

zapier.com > Dashboard > Create Zap > Trigger

Create a new Zap and connect Gmail

Log into zapier.com and click the orange 'Create Zap' button in the left sidebar. The Zap editor opens with a blank trigger slot. Click the trigger box and type 'Gmail' in the search field. Select 'Gmail' from the results — you'll see the Google logo and 'Gmail' label. You need to connect the specific Google account that owns your support inbox, not a personal account.

1. 1Click 'Create Zap' in the left sidebar
2. 2Click the empty trigger box labeled 'Trigger'
3. 3Type 'Gmail' in the app search field
4. 4Select 'Gmail' from the dropdown results

Zap Editor > Trigger > App & Event > Event dropdown

Select the 'New Email' trigger event

With Gmail selected as the trigger app, click the 'Event' dropdown below the app name. Scroll to find 'New Email' — this fires every time a new email arrives in a specified label or inbox. Do not choose 'New Email Matching Search' yet; select plain 'New Email' first to connect your account, then you'll add label filtering in the next step. Click 'Continue' after selecting the event.

1. 1Click the 'Event' dropdown under the Gmail trigger block
2. 2Scroll down and select 'New Email'
3. 3Click 'Continue'

Zap Editor > Trigger > Gmail Account > Sign in to Gmail

Authenticate your Gmail support account

Click 'Sign in to Gmail'. A Google OAuth popup appears — sign in with the Google account tied to your support inbox. Google will ask you to grant Zapier permission to read and send email. You only need read access for this workflow, but Zapier requests both. After granting access, you'll return to the Zap editor and see your account email listed under the trigger. Click 'Continue'.

1. 1Click 'Sign in to Gmail'
2. 2Select the correct Google account in the OAuth popup
3. 3Click 'Allow' on the permissions screen
4. 4Confirm the account email shown in the editor matches your support inbox
5. 5Click 'Continue'

Zap Editor > Trigger > Configure > Label/Mailbox

Configure the Gmail label filter

Zapier shows a 'Configure' screen with a 'Label/Mailbox' field. Click the dropdown and select the Gmail label you want to monitor — typically 'INBOX' for an unfiltered support inbox, or a custom label like 'Support' if you've set up Gmail filters that tag inbound support emails. If you use a dedicated support@ address in Google Workspace, selecting 'INBOX' will catch everything sent to that account. Click 'Continue' after selecting the label.

1. 1Click the 'Label/Mailbox' dropdown
2. 2Select 'INBOX' or your custom support label
3. 3Leave all other fields blank
4. 4Click 'Continue'

Zap Editor > Trigger > Test > Test trigger

Test the Gmail trigger

Click 'Test trigger' — Zapier fetches the 3 most recent emails from the selected label and shows them as sample records. Pick the sample that looks most like a real support email (a message from a customer, not an automated digest). You'll use the fields from this sample — From Name, From Email, Subject, Body Plain — in the Slack message later. Confirm the fields are populated correctly before moving on.

1. 1Click 'Test trigger'
2. 2Review the list of fetched email samples
3. 3Click the sample that best represents a real support ticket
4. 4Verify 'From Name', 'From Email', 'Subject', and 'Body Plain' fields contain real data

Zap Editor > + Add Action > Formatter by Zapier > Text > Truncate

Add a Formatter step to truncate the email body

Click the '+' button below the trigger to add an action step. Search for 'Formatter by Zapier' and select it. Choose 'Text' as the action event, then select 'Truncate' as the transform. In the 'Input' field, map the 'Body Plain' field from your Gmail trigger. Set 'Max Length' to 300 and 'Append Ellipsis' to Yes. This ensures your Slack message stays readable — a 10-paragraph support email pasted raw into Slack destroys channel readability.

1. 1Click the '+' button below the Gmail trigger
2. 2Search for and select 'Formatter by Zapier'
3. 3Select 'Text' as the action event
4. 4Select 'Truncate' as the transform type
5. 5Map 'Body Plain' from the Gmail step into the 'Input' field
6. 6Set 'Max Length' to 300 and enable 'Append Ellipsis'

Zap Editor > + Add Action > Slack > Send Channel Message

Connect Slack as the action app

Click the '+' button below the Formatter step to add a second action. Search for 'Slack' and select it. Choose 'Send Channel Message' as the action event — this posts a message to a public or private channel your bot has access to. Click 'Continue', then authenticate with the Slack workspace where your #support channel lives. Zapier will ask you to authorize the Zapier Slack bot and select which workspace to connect.

1. 1Click the '+' button below the Formatter step
2. 2Search for and select 'Slack'
3. 3Select 'Send Channel Message' as the action event
4. 4Click 'Continue'
5. 5Click 'Sign in to Slack' and authorize the Zapier bot in your workspace

Zap Editor > Slack Action > Configure > Channel + Message Text

Configure the Slack message fields

In the Slack action configuration, set 'Channel' to your support channel (e.g., #support or #tickets). In the 'Message Text' field, build your formatted summary by clicking into the field and inserting dynamic values from the Gmail trigger and Formatter step. A clear format: start with the sender and subject on line one, add the truncated body on line two, then add a direct link to the email thread using the Gmail 'Thread ID' field. Set 'Bot Name' to something like 'Support Bot' and choose an emoji icon like :mailbox:.

1. 1Select your support channel from the 'Channel' dropdown
2. 2Click into the 'Message Text' field
3. 3Type '*New ticket from* ' then insert the 'From Name' field
4. 4Add a newline, type '*Subject:* ' then insert the 'Subject' field
5. 5Add another newline and insert the truncated output from the Formatter step
6. 6Set 'Bot Name' to 'Support Bot' and choose a bot icon emoji

Zap Editor > Slack Action > Configure > Message Text (continued)

Add a direct Gmail link to the Slack message

Scroll down in the Slack action configuration to find the 'Message Text' field where you're building the notification. Add a final line with the text 'Open in Gmail: ' followed by a constructed URL. The format is https://mail.google.com/mail/u/0/#inbox/ followed by the Gmail 'Thread ID' field mapped from the trigger. This gives agents a one-click path from Slack to the actual email thread in Gmail without hunting through their inbox.

1. 1Position your cursor at the end of the Message Text field
2. 2Add a new line and type 'Open in Gmail: https://mail.google.com/mail/u/0/#inbox/'
3. 3Click the variable picker icon and insert the 'Thread ID' field from the Gmail trigger
4. 4Click 'Continue'

Zap Editor > Slack Action > Test > Test action

Test the full Zap and verify the Slack message

Click 'Test action' in the Slack configuration step. Zapier sends a test message to your chosen channel using the sample Gmail data. Open Slack and navigate to the #support channel to verify the message posted correctly. Check that the sender name, subject, and truncated body all appear as expected, and click the Gmail link to confirm it opens the correct thread.

1. 1Click 'Test action' in the Slack step
2. 2Open Slack and navigate to your support channel
3. 3Verify the test message shows sender, subject, and body preview
4. 4Click the Gmail link in the message to confirm it opens the correct thread

Zap Editor > Publish Zap > Name & Activate

Turn on the Zap

Click 'Publish Zap' in the top right of the editor. Zapier will prompt you to name the Zap — use something descriptive like 'Gmail Support → Slack #support'. The Zap turns on immediately and begins polling your Gmail inbox at your plan's polling interval. On a Starter plan this is every 15 minutes. On Professional it's every 2 minutes. Send a test email to your support address and wait for it to appear in Slack.

1. 1Click 'Publish Zap' in the top right corner
2. 2Enter a descriptive name for the Zap
3. 3Click 'Publish' to confirm and activate
4. 4Send a real test email to your support address
5. 5Wait for the Slack notification to appear based on your plan's polling interval

Paste this into a 'Code by Zapier' step (Python mode) placed between the Formatter step and the Slack step. It classifies ticket urgency based on keywords in the subject and body, then prepends a colored emoji indicator to the Slack message — red circle for urgent, yellow for medium, green for low — so agents can triage without reading the full message.

# Input variables (set these in the 'Input Data' section):
