Step-by-Step: Build Your First Automation in N8N

Step 1: Launch N8N

Open your N8N editor in your browser. If you’re using the cloud version, log in to your n8n.cloud account. If self-hosted, access it via your configured domain or localhost. Click “New Workflow” to begin.

Step 2: Add the Gmail Trigger Node

1. Click the “+” icon to add a new node.
2. Search for “Gmail” and select it.
3. Choose the “Trigger” operation to watch for new emails.
4. Connect your Gmail account (you may need to authenticate).
5. Set filters (e.g., watch only unread emails, or emails from a specific address).

Step 3: Add the Slack Node

1. Click the “+” to add another node.
2. Search for “Slack” and choose it.
3. Select the “Send Message” operation.
4. Connect your Slack workspace.
5. Define the channel and customize the message content (you can use dynamic variables from Gmail like subject, sender, etc.).

Step 4: Connect the Nodes

Drag your mouse from the Gmail node to the Slack node to connect them. This tells N8N to perform the Slack action after the Gmail trigger fires.

Step 5: Test the Workflow

1. Click “Execute Workflow” to test it.
2. Send yourself a test email.
3. If configured correctly, you’ll receive a Slack message in seconds.

Step 6: Activate the Workflow

Click the toggle to activate the workflow. It will now run continuously in the background, watching for new emails and sending Slack alerts.
