Automate Lead Enrichment & CRM Updates with Clearbit, HubSpot, ConvertKit

What This Automation Does

This workflow watches for new subscribers on a certain ConvertKit form. It ignores personal email addresses like Gmail or Yahoo. Then it fetches detailed info about the person using Clearbit’s person API. If the person works at a company, it fetches company info too. The workflow looks in HubSpot CRM to find the company. If the company is not there, it creates it. If the company exists, it updates the record. Then, the contacts and leads are added or updated in HubSpot and linked with the company record.

The goal is to save time and avoid manual errors. The CRM stays up to date with accurate, enriched info about leads and companies.

Tools and Services Used

• ConvertKit: Sends new subscriber data from a specific form.
• Clearbit Person API: Provides enriched data about the lead based on email.
• Clearbit Company API: Retrieves detailed company information by domain.

• n8n Automation Platform: Runs the workflow linking all these services.
