Description

(Retail Automation) Gmail Trigger → Spam Filter → Duplicate Check → Zendesk Ticket Creation

This workflow automatically converts incoming support emails from Gmail into structured Zendesk tickets. It filters spam, extracts key customer details, auto-tags issues, prevents duplicate tickets and creates clean, actionable support tickets in Zendesk.

Quick Implementation Steps

1. Connect your Gmail support inbox to the Gmail Trigger.
2. Configure spam keywords and domains in the Spam Detection node.
3. Map email fields in the Set node.
4. Connect your Zendesk account.
5. Activate the workflow.

What It Does

This workflow listens for new emails arriving in a Gmail support inbox and immediately processes them through a clean automation pipeline. Spam or suspicious emails are filtered early to keep the support system noise-free.

Valid emails are normalized by extracting customer details such as name, email, subject, message content and thread ID. The workflow automatically tags tickets based on keywords like “refund” or “damaged” for better prioritization.

Before creating a new ticket, the workflow checks existing Zendesk tickets to avoid duplicates. Only genuine, new requests are converted into Zendesk tickets with all required fields populated.

Who’s It For

• Customer support teams using Gmail and Zendesk
• Small to mid-sized businesses handling email-based support
• Operations teams looking to reduce manual ticket creation
• Support managers who want clean, duplicate-free ticket queues

Requirements

• n8n instance (self-hosted or cloud)
• Gmail account with access to the support inbox
• Zendesk account with API access enabled
• OAuth credentials for Gmail and Zendesk
