This article provides a complete, practical walkthrough of the Mautic Gmail Send Triggered n8n agent. It connects HTTP Request, Webhook across approximately 1 node(s). Expect a Intermediate setup in 15-45 minutes. One‑time purchase: €29.

What This Agent Does

This agent orchestrates a reliable automation between HTTP Request, Webhook, handling triggers, data enrichment, and delivery with guardrails for errors and rate limits.

It streamlines multi‑step processes that would otherwise require manual exports, spreadsheet cleanup, and repeated API requests. By centralizing logic in n8n, it reduces context switching, lowers error rates, and ensures consistent results across teams.

Typical outcomes include faster lead handoffs, automated notifications, accurate data synchronization, and better visibility via execution logs and optional Slack/Email alerts.

How It Works

The workflow uses standard n8n building blocks like Webhook or Schedule triggers, HTTP Request for API calls, and control nodes (IF, Merge, Set) to validate inputs, branch on conditions, and format outputs. Retries and timeouts improve resilience, while credentials keep secrets safe.

   Automating Mautic Unsubscribes with n8n and Gmail
   
   In today’s fast-paced digital marketing landscape, maintaining contact list hygiene and honoring unsubscribe requests promptly are essential. Failing to do so can not only annoy your contacts but also damage sender reputation and violate privacy laws. If your team uses Mautic for email marketing and Gmail for communication, this n8n automation workflow can help handle unsubscribe requests with no manual effort.
   
   In this guide, we’ll explore a custom n8n workflow titled "Unsubscribe Mautic contacts from automated unsubscribe emails" that does exactly that—listens for unsubscribe requests via email and updates Mautic contact segments automatically.
   
   Overview of the Workflow
   
   This n8n workflow automatically monitors incoming unsubscribe emails in Gmail. It processes each request by checking whether the sender is a real Mautic contact. If so, it removes them from the main newsletter segment, adds them to an unsubscribed segment, and replies with a confirmation message. Here's how it works step-by-step.
   
   Step 1: Gmail Trigger
   
   The automation starts with the Gmail Trigger node. This node polls the Gmail inbox every minute, including messages from the spam and trash folders. This frequent check ensures no unsubscribe request goes unnoticed.
   
   Step 2: Identify Automated Unsubscribe Emails
   
   The next node is a conditional IF node named "Is automated unsubscribe?". This node checks two conditions:
   
   - The recipient address (To) contains the word “unsubscribe”.
   - The sender (From) is not the company’s own email (configured via the 'Edit Fields' node), avoiding false positives.
   
   Only emails that meet both criteria proceed in the workflow.
   
   Step 3: Extract the Sender’s Email Address
   
   Once a valid unsubscribe email is detected, a Code node extracts the email address from the ‘From’ field. It supports both plain addresses (e.g., test@example.com) and formatted addresses (e.g., John Doe <john@example.com>). The next Code node ensures uniqueness by creating a deduplicated list of email addresses.
   
   Step 4: Look Up the Contact in Mautic
   
   Using the extracted emails, the workflow calls Mautic’s API to search for the contact by email address. This is done through the “Get Mautic Contact ID from Email Address” node. Only emails belonging to existing Mautic contacts proceed to the next steps.
   
   Step 5: Update Mautic Segments
   
   For verified contacts, the following actions are performed via Mautic nodes:
   
   - Remove them from the newsletter segment (Segment ID: 1).
   - Add them to the "unsubscribed" segment (Segment ID: 3).
   - (Optional) Mark them as "Do Not Contact" (this step is currently disabled but can be enabled by user).
   
   These actions ensure the contact will no longer receive campaign emails, placing them in a clearly labeled segment for future reference.
   
   Step 6: Send a Confirmation Reply
   
   Finally, using another Gmail node, the workflow replies to the sender confirming their unsubscribe status. The reply message is customizable via the "Edit Fields" node. In this example, the default message is:
   
   “Your have successfully opted out from our marketing campaigns. Please reply if you believe this is an error.”
   
   Custom Configuration Tips
   
   The workflow includes sticky notes throughout, guiding the user through setup:
   
   - Step 1: Set your email address and custom unsubscribe reply message in the “Edit Fields” node.
   - Step 2: Configure your Gmail credentials in the Gmail Trigger and Gmail reply nodes.
   - Step 3: Set up Mautic credentials across all Mautic nodes.
   - Step 4: Update the segment IDs if your Mautic instance uses different values.
   
   Benefits of this Workflow
   
   - Saves time: Entire process happens automatically with no need for manual list cleaning.
   - Reduces errors: Ensures unsubscribe requests are correctly handled and acknowledged.
   - Improves compliance: Helps stay in line with email marketing laws like GDPR or CAN-SPAM.
   - Enhances customer experience: Immediate and personalized confirmation emails reassure your users.
   
   Final Thoughts
   
   Automating unsubscribes sounds simple, but doing it reliably and consistently across tools like Gmail and Mautic takes effort. By leveraging n8n’s powerful automation features, this workflow bridges your email inbox with your marketing automation data, streamlining communication and contact management.
   
   If you’re running Mautic and regularly receive unsubscribe replies, implementing this workflow can dramatically reduce the workload while ensuring a better user experience and higher compliance.
   
   With just a few credentials and configurations, this no-code approach turns a tedious manual task into an elegant automated solution.

5. Set credentials for each API node (keys, OAuth) in Credentials.
6. Run a test via Execute Workflow. Inspect Run Data, then adjust parameters.
7. Enable the workflow to run on schedule, webhook, or triggers as configured.

Tips: keep secrets in credentials, add retries and timeouts on HTTP nodes, implement error notifications, and paginate large API fetches.

Validation: use IF/Code nodes to sanitize inputs and guard against empty payloads.

Why Automate This with AI Agents

AI‑assisted automations offload repetitive, error‑prone tasks to a predictable workflow. Instead of manual copy‑paste and ad‑hoc scripts, your team gets a governed pipeline with versioned state, auditability, and observable runs.

n8n’s node graph makes data flow transparent while AI‑powered enrichment (classification, extraction, summarization) boosts throughput and consistency. Teams reclaim time, reduce operational costs, and standardize best practices without sacrificing flexibility.

Compared to one‑off integrations, an AI agent is easier to extend: swap APIs, add filters, or bolt on notifications without rewriting everything. You get reliability, control, and a faster path from idea to production.

Best Practices

• Credentials: restrict scopes and rotate tokens regularly.
• Resilience: configure retries, timeouts, and backoff for API nodes.
• Data Quality: validate inputs; normalize fields early to reduce downstream branching.
• Performance: batch records and paginate for large datasets.
• Observability: add failure alerts (Email/Slack) and persistent logs for auditing.
• Security: avoid sensitive data in logs; use environment variables and n8n credentials.

FAQs

Can I swap integrations later? Yes. Replace or add nodes and re‑map fields without rebuilding the whole flow.

How do I monitor failures? Use Execution logs and add notifications on the Error Trigger path.

Does it scale? Use queues, batching, and sub‑workflows to split responsibilities and control load.
