Capture contact form entries, screen out personal emails, and send a fast reply to high value business leads. Ideal for B2B teams that want quick follow up and better lead quality from a simple contact form.

Form data flows into n8n first. The email field is mapped to a clean value. A filter removes free email domains so only business emails pass through. Clearbit enriches the person by email and then looks up the company by domain. A decision checks if the lead is B2B and the company has more than 499 employees. If it matches, Gmail sends a personalized message using the contact’s first name from Clearbit. If it does not match, nothing is sent and the run ends.

You will need a Clearbit API key and a Gmail account connected in n8n Cloud. Adjust the filter list and the employee threshold to match your ideal customer profile. Edit the email copy to match your brand. Expect faster replies, fewer low value leads, and more time focused on accounts that matter. Great for B2B SaaS forms, agencies working with larger firms, and teams that want to qualify leads before a reply.
