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

   Automated Email Verification in n8n Using uProc: A Simple Workflow Example
   
   In the digital age, ensuring the accuracy and deliverability of email addresses is vital. Whether you're onboarding users, distributing newsletters, or managing a customer database, validating email addresses saves you time and prevents miscommunication. With n8n, an extendable workflow automation tool, and third-party services like uProc, you can build powerful automation with minimal coding. In this article, we’ll explore a compact yet effective n8n workflow that performs email address verification using the uProc API.
   
   The Goal
   
   The primary goal of this workflow is to verify if a given email address is valid and deliverable. We’ll walk through a basic four-node setup in n8n that checks the status of an email address using uProc’s checkEmailExists tool and routes the result accordingly.
   
   Let’s break down the workflow:
   
   Workflow Overview
   
   Here are the four primary nodes in the workflow:
   
   1. Manual Trigger
   2. Create Email Item
   3. Check Email Exists (via uProc)
   4. If Condition (Email Exists?)
   
   Now, let’s dive into each one to understand how they come together.
   
   1. Manual Trigger Node
   
   Node Name: On clicking 'execute'  
   Type: Manual Trigger
   
   This node is the starting point of the workflow. It allows you to trigger the process manually within the n8n UI for testing purposes. Once triggered, it moves the flow to the next node.
   
   Use Case: Ideal for initial testing, development, or debugging workflows before deploying them with a scheduled or webhook trigger.
   
   2. Create Email Item
   
   Node Name: Create Email Item  
   Type: FunctionItem
   
   This node injects the email address to be verified. In our example, it hardcodes the email mcolomer@gmail.com into the workflow.
   
   Code:
   ```javascript
   item.email = "mcolomer@gmail.com";
   return item;
   ```
   
   This step is often used for prototyping. In production, it would typically pull the email dynamically from a form submission, database, or API request.
   
   3. Check Email Exists via uProc
   
   Node Name: Check Email Exists  
   Type: uProc Node  
   Tool Used: checkEmailExists  
   Email Parameter: Dynamically set from the previous node
   
   This node is responsible for interacting with the third-party uProc API to verify the email’s deliverability. The email address obtained from the previous step is passed to uProc’s checkEmailExists tool.
   
   uProc returns a response—typically 'deliverable', 'undeliverable', 'risky', or 'unknown'. This provides you with a clear indication of whether the email can be used safely or should be discarded.
   
   Note: API credentials ("miquel-uproc") are used here to authorize access to the uProc API.
   
   4. "Email Exists?" (If Condition)
   
   Node Name: Email Exists?  
   Type: IF Node
   
   Once the response from uProc is received, the If node evaluates whether the email’s deliverability status equals “deliverable”.
   
   Logic:
   Compare →  
   Value 1: {{$node["Check Email Exists"].json["message"]["response"]}}  
   Operator: Equals  
   Value 2: deliverable
   
   If the condition is true, the workflow could continue down a “true” path for verified emails. Otherwise, it can log, reject, or handle invalid emails in another branch (not included in this minimal setup).
   
   Extending the Workflow
   
   While this basic email verification workflow provides value on its own, here are some ideas on extending it:
   
   - Add a new node to log results to Google Sheets or Airtable for documentation.
   - Include email notification nodes (SMTP or Gmail) to alert users about verification failures.
   - Use a webhook instead of a manual trigger to verify emails submitted via a web form in real-time.
   - Set conditions for risky and unknown status responses to decide on soft rejections.
   
   Why Use uProc in n8n?
   
   uProc’s API gives detailed enrichment options, including email validation, phone verification, and much more. By combining uProc with n8n's logic control and data manipulation capabilities, you can automate complex workflows without writing standalone applications.
   
   Benefits of This Approach
   
   - Accuracy: Reduces bounced emails and improves sender reputation.
   - Automation: Saves time by removing manual verification steps.
   - Integration: Easily expandable using n8n’s numerous integrations (SMTP, CRM tools, databases, etc.).
   - Cost-effective: Run on your own infrastructure with minimal external dependencies.
   
   Conclusion
   
   Verifying email addresses is a foundational step in any digital communication strategy. Using no-code/low-code tools like n8n along with third-party services like uProc makes it easy to automate this process efficiently. The workflow above not only demonstrates the simplicity of setting up a working email validation pipeline but also lays the groundwork for more advanced automation solutions.
   
   Whether you're managing marketing contacts or building sign-up workflows, email validation should be part of your automation arsenal—and with n8n and uProc, it's never been easier.

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.
