Enrich new form leads with Lusha, HubSpot, and Slack alerts
High-converting forms are short, but short forms usually lead to thin CRM data. This play solves that conflict by using a webhook to intercept every form submission in real time. The workflow first validates the email and checks HubSpot to see if the contact already exists (i.e. preventing duplicate records).
If the lead is new or needs updated data, Lusha enriches the profile with a verified phone number, job title, seniority, and firmographic company details. The system then merges the original form responses with this fresh intelligence, updates HubSpot, and pings an SDR on Slack with a ready-to-call lead profile.
Why this works
Every additional field on a web form reduces conversion rates. However, every missing field increases the time an SDR spends on manual research.
This play operationalizes conversion by:
- Reducing form friction: Allowing you to ask for just an email while still getting a full profile.
- Intelligent de-duplication: Checking your CRM first to ensure you aren’t creating messy data or alerting reps to existing accounts.
- Instant sales readiness: Delivering the direct dial and job seniority to Slack before the prospect even closes their browser tab.
- System sync: Returning a JSON response to your website, which can be used to trigger personalized “Thank You” messages based on the enriched data.
What you get
- Webhook-triggered processing for any web form
- Automated email validation and HubSpot duplicate checking
- Real-time enrichment (i.e. phone, title, seniority, and company data) via Lusha
- Unified data upsert into HubSpot CRM
- Instant SDR notifications in Slack with lead context
How to set it up
Install the Lusha community node
Ensure your n8n instance has the @lusha-org/n8n-nodes-lusha node installed to communicate with the Lusha API.
Connect your core apps
Securely link your credentials in n8n for:
- Lusha: For real-time data enrichment.
- HubSpot: Via OAuth2 to manage contact records and check for duplicates.
- Slack: To alert the sales team of new inbound interest.
Point your form to the webhook
Copy the n8n webhook URL and set it as the “Action URL” or “Webhook Destination” in your form builder (i.e. Webflow, Typeform, or a custom HTML form).
Configure the duplicate check
Ensure the HubSpot node is set to search for the contact by email. If a match is found, the workflow should update the existing record rather than creating a new one.
Map Lusha data to HubSpot
Map the Lusha output fields (i.e. mobile_phone, seniority, industry) to your specific HubSpot properties.
Set up the SDR alert
Configure the Slack node to post to your #new-leads or #sales channel. Include the enriched job title and the direct dial so the rep can follow up immediately.
What to do next
- Personalized routing: Add a “Switch” node after enrichment to route leads to different Slack channels based on “Industry” or “Company Size.”
- Conditional content: Use the webhook’s JSON response to redirect “High Seniority” leads to a booking page while sending “Junior” leads to a resource library.
- SLA tracking: Use the Slack timestamp and HubSpot “Created Date” to measure exactly how fast your reps are responding to these enriched alerts.
The goal: Maximize inbound conversions without sacrificing data quality. This play ensures that your reps have the data they need to be relevant and fast, while your prospects enjoy a frictionless form experience.
