This article provides a complete, practical walkthrough of the Hubspot Mailchimp Create Scheduled 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.

   In today’s competitive digital landscape, speed and personalization are essential for effective lead nurturing. Whether you’re welcoming new subscribers or segmenting contacts based on behavior, making sure your systems are in sync can streamline your marketing workflow and improve communication. In this article, we’ll walk you through a simple, automated n8n workflow that syncs new HubSpot contacts to a Mailchimp mailing list every day at 7:00 AM. With no manual effort, your email marketing stays updated and ready to engage new leads as soon as they arrive.
   
   Why n8n?
   
   n8n is a powerful open-source workflow automation tool that allows you to connect various applications and services without needing deep developer expertise. Its easy visual interface and node-based design make it an excellent choice for automating repetitive tasks such as syncing data between marketing platforms.
   
   Overview of the Workflow
   
   This n8n workflow consists of three core steps:
   
   1. A trigger that activates every day at 7:00 AM.
   2. Fetching all new HubSpot contacts created within the last 24 hours.
   3. Adding those contacts directly to a Mailchimp list with mapped first and last names.
   
   Let’s break it down.
   
   Step 1: Scheduled Trigger ("Every day at 07:00")
   
   The first node in the workflow is a Cron node — a time-based trigger that runs the workflow at a specific time every day. In this case, it's configured to run daily at 7:00 AM. This ensures that the automation checks for new contacts on a consistent schedule, perfect for early-morning processing before your business day begins.
   
   Step 2: Fetch New HubSpot Contacts
   
   The next node uses the HubSpot API via OAuth2 authentication to search for new contacts. Specifically, it applies a filter to gather contacts that were created during the previous day. It achieves this by using dynamic date expressions:
   
   - "GTE" (Greater Than or Equal to) yesterday’s midnight (start time)
   - "LT" (Less Than) today’s midnight (end time)
   
   This makes sure that only new contacts from the last 24 hours are retrieved — no duplicates, and no outdated entries.
   
   The use of filter groups and property operators like createdate allows you to target precisely the timeframe and contact properties that matter most to your marketing workflow.
   
   Step 3: Add Contacts to Mailchimp List
   
   Once the new contacts are retrieved from HubSpot, each one is passed to the Mailchimp node. This step subscribes each contact to a specific list (in this case, list ID 8965eba136) using their email address, first name, and last name.
   
   Mailchimp’s OAuth2 authenticated API is used for secure communication, and merge fields are utilized to ensure that user data is mapped properly in Mailchimp. The contacts are added with a “subscribed” status, which means they’ll immediately start receiving campaigns or welcome emails depending on your Mailchimp configuration.
   
   The Big Picture: Automated Lead Syncing
   
   This workflow exemplifies how automation can make your marketing operations more efficient. Let’s consider the benefits:
   
   - Time-saving: Your marketing team doesn’t have to manually export and import contact lists every day.
   - Accuracy: Daily automation ensures consistent data without human error or delays.
   - Lead Engagement: New leads are nurtured immediately, reducing the time between when a user signs up and when they receive communication.
   
   Advanced Customizations
   
   For those interested in building on this workflow, there’s plenty of room for customization:
   
   - Add conditional filters to sort contacts by source or lifecycle stage before pushing to Mailchimp.
   - Integrate with Slack or email for daily summaries or error alerts.
   - Use additional transformations to clean or enrich the data before passing it on.
   
   Conclusion
   
   If you’re managing leads using HubSpot and engaging them through Mailchimp, this n8n workflow is a game-changer. With just a few nodes and scheduled execution, you ensure that your email list is always up to date and that your new leads are instantly brought into your nurturing funnel.
   
   Whether you’re a small business owner looking to save time or a marketer aiming to enhance your automation strategy, this solution is an excellent place to begin.
   
   Start leveraging n8n today — and let your marketing workflows work for you while you sleep.

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.
