Why Use CSV Import/Export
Not all leads come from LinkedIn or integrations—and sometimes you need to enrich and segment large lists quickly. CSV import/export helps you bridge your existing workflows with ReactIn’s targeting power.
Import Leads into a SmartList
Instantly upload your own list of leads into ReactIn and enrich them using SmartColumns (LinkedIn + AI).
File Requirements
Make sure your CSV follows these formatting rules:
✅ File must be in
.csvformat✅ The first row must include column headers
✅ One column must contain either
emailorlinkedinUrl✅ Optional columns:
firstName,lastName,customVariable1,customVariable2, etc.
For best results:
Include first name, last name, email, and LinkedIn URL in your CSV. This maximizes enrichment quality and personalization later.
Use Case Example:
Upload a CSV from your CRM, enrich with profile headlines, and launch a campaign targeting only Founders or VPs.

Export Leads from a SmartList
Need to sync with your CRM or reporting tools? Just hit Export CSV and get all your SmartList data, including:
all the lead data
Enriched LinkedIn and/or AI columns, if they exist
Use Case Example:
Export all leads you interact with your competitor LinkedIn posts
💡 Pro tip: Combine CSV import with SmartColumns and filters to transform static lists into personalized LinkedIn campaigns in minutes.
