This article provides a complete, practical walkthrough of the Manual Sendy Create 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.

   Email marketing is one of the most effective ways for businesses and creators to engage with their audiences. Tools like Sendy provide a cost-effective, self-hosted solution, especially when integrated into automation platforms like n8n. In this article, we'll explore a simple yet powerful n8n workflow that streamlines two core functions of email marketing: adding a new subscriber to a mailing list and sending them a welcome campaign.
   
   What is n8n?
   
   n8n is a fair-code automation platform that allows users to connect various services and automate repetitive tasks without writing complex code. With a drag-and-drop interface and hundreds of pre-built integrations, n8n is a popular choice for developers and marketers looking to boost efficiency.
   
   The Workflow: Overview
   
   The n8n workflow discussed here consists of three key steps:
   
   1. Manual Trigger — kicks off the automation manually.
   2. Add Subscriber to Sendy List — enrolls a new contact into a designated email list.
   3. Create and Send Campaign — immediately launches a custom campaign to the newly added subscriber.
   
   Let's break it down step-by-step.
   
   Step 1: Manual Trigger
   
   The process starts with a Manual Trigger node labeled "On clicking 'execute'". This node allows you to run the workflow on-demand, which is incredibly useful for testing your automation before setting up a more complex trigger like a webhook or interval timer.
   
   This ensures that the entire process can be verified right within the n8n interface, providing instant feedback and control.
   
   Step 2: Add Subscriber to Sendy
   
   Once the workflow is triggered, the next node uses the Sendy node to add a subscriber to a predefined list. The parameters indicate that the email harshil@n8n.io with the name "Harshil" is being added to list ID 2. This step ensures that your new contact is registered in Sendy's database so they can begin receiving communications.
   
   The node requires authentication via Sendy API credentials, which you can set up in n8n’s Credential Manager. This connection enables seamless communication between n8n and your self-hosted Sendy installation.
   
   Parameter Highlights:
   - email: harshil@n8n.io
   - name: Harshil
   - listId: 2
   
   Step 3: Create and Send a Campaign
   
   The final node, labeled "Sendy1", leverages the same Sendy API to create a new email campaign and send it immediately. The campaign welcomes the new subscriber to the platform, using both a clear subject line and a simple HTML email structure.
   
   The key parameters include:
   - title: Welcome to n8n
   - replyTo / fromEmail: docs@n8n.io
   - subject: Welcome to n8n
   - fromName: n8n
   - htmlText: A simple welcome message in HTML format
   - listIds: 2 (delivers to the same list we just added the subscriber to)
   - sendCampaign: true (ensures automatic delivery once the campaign is created)
   
   The immediate delivery of the campaign streamlines the onboarding experience for a new subscriber. This is crucial in maintaining engagement and reinforcing branding the moment a user joins your list.
   
   Why Use n8n with Sendy?
   
   Combining n8n with Sendy brings together the best of both worlds:
   
   - Flexibility: Customize your campaigns, lists, and automation flows easily.
   - Cost-Effectiveness: Unlike SaaS solutions, Sendy runs on Amazon SES, drastically lowering email marketing costs.
   - Expandability: Add more steps like CRM integration, tagging, segmentation, or data logging with ease using n8n.
   
   Real-World Applications
   
   This workflow is not just limited to welcoming a new user. With just a few tweaks, the same logic can be used for:
   
   - Drip marketing campaigns
   - Newsletter onboarding
   - Course delivery automation
   - Lead nurturing
   
   Getting Started
   
   To replicate this workflow, make sure you have:
   
   - A running instance of n8n (self-hosted or cloud)
   - Sendy installed and configured with a valid Amazon SES setup
   - API credentials for Sendy added in n8n’s credential manager
   
   Once configured, build the workflow using the Manual Trigger and two Sendy nodes, then test it manually before deploying it with a scheduled or webhook trigger.
   
   Conclusion
   
   This simple n8n workflow demonstrates the power of automation in scaling your email marketing efforts. By integrating with Sendy, you can manage subscribers and launch email campaigns instantly, saving time while enhancing user experience. Whether you're a marketer, developer, or startup founder, combining n8n and Sendy could be a game-changer for your outreach strategies.

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.

Is my data safe? Keep secrets in Credentials, restrict token scopes, and review access logs.
