Sales and marketing teams often work with CSV lists: event attendees, webinar signups, or leads exported from other systems. But raw lists are usually incomplete, missing phone numbers, emails, or company details — which slows down outreach and lowers campaign ROI. With Lusha and n8n, you can enrich entire lists in bulk automatically and sync them back into your CRM or outreach tool.
Why this workflow works
- Faster campaign readiness: Turn raw spreadsheets into complete, usable lead lists in hours, not days.
- Verified data at scale: Every row is enriched with up-to-date, accurate contact details.
- Consistent reporting: Standardized job titles, industries, and regions make segmentation easier.
- Better ROI on events: Event and webinar leads turn into revenue opportunities faster.
The workflow step by step
- Trigger: Upload a CSV file (event list, marketing campaign file, or export from another system) to a cloud folder or directly into n8n.
- Batch enrichment: n8n sends the list to Lusha’s Bulk API. Each row is enriched with verified phone, email, and company details.
- Quality control: Records with low-confidence data are flagged for manual review.
- Normalization: Titles, industries, and company size are standardized.
- Sync & distribute: Enriched list is pushed to your CRM (Zoho, Salesforce, HubSpot) or directly to outreach tools like Outreach or SalesLoft.
Real-world example
- Trigger: CSV of 1,000 trade show attendees uploaded to Google Drive.
- Action: n8n workflow detects upload, sends rows to Lusha Bulk API.
- Filter: Keep only verified emails with >90% confidence.
- Action: Update enriched contacts in Salesforce.
- Optional: Send Slack message to sales team: “Event list enriched. 950 verified contacts ready.”
KPIs to track
- % of list enriched with verified contacts.
- Time from event end to campaign launch.
- Response rates from enriched vs. raw lists.
- Revenue contribution from event/webinar campaigns.
Best practices
- Always enrich lists immediately after the event while interest is fresh.
- Use filters in n8n to exclude low-confidence or outdated emails.
- Normalize data to keep CRM reports clean and consistent.
- Run quarterly checks on old campaign lists to refresh them.
