n8n Lead Email Automation Expert With experience

I need a set of production-ready n8n workflows that automatically capture every new lead—whether it comes from a website form, a paid ad, or a social post—and push the data straight into our CRM (HubSpot, Salesforce, or Zoho). The moment a record is created, an email or message sequence should launch on its own, keeping the prospect warm without anyone on my team lifting a finger.

Here is what has to happen, end to end:

• New lead hits a form or ad → n8n grabs the payload, cleans the data, tags the source, and writes it to the chosen CRM.
• A personalised follow-up email or chat message is triggered immediately, with optional delays and branching logic for day-two and day-seven nudges.
• Every touch point is logged back to the same CRM record so sales reps can see a complete timeline.
• Fail-safes: retries on API errors, Slack or email alerts if something breaks, and clear logging for quick debugging.

Deliverables
1. Importable n8n workflow JSON files for each step (lead capture, CRM update, follow-up sequence).
2. A quick Loom or similar walkthrough that proves the flow runs from lead entry to final email.
3. A short README outlining required environment variables, credentials, and how to scale or clone the setup.

I’d like to see examples of live n8n automations you have built before—especially anything touching HubSpot, Salesforce, or Zoho—so include a link or brief summary in your response.
