CSV enrichme is a dedicated enrichment hub that lets you upload large lists of contacts and automatically fill in missing or outdated data - business emails, direct dials, job titles, company details, and more.
Use Enrich when you already have a list and need to complete it, rather than building a new list from scratch.
💡 Note: Each plan has a different row limit per enrichment: Free — 100 rows | Professional — up to 300 | Premium — up to 500 | Scale — up to 10,000. You can enrich as many files as your credits allow.
What you can do with Enrich
Upload a CSV file of contacts with partial information (name, company, LinkedIn URL, or email) and Lusha will match each row against its database and return verified data for every field it can fill.
Enrich is designed for volume. It handles large batches efficiently and gives you a clean, exportable file when it's done.
How to enrich a list
Go to Enrich > CSV Enrichment in the left navigation, or go directly here.
Click Upload CSV and select your file. Your CSV must contain at least one of the following:
Required data | Example |
A LinkedIn profile URL (optimal) | |
Full name + Company name | John Smith | Lusha |
The file must also meet these requirements: CSV format only, no more than 20 MB, no more than 10,000 rows.
3. Map your file's columns to Lusha's fields (e.g. map "Full Name" → First Name + Last Name, "Company" → Company Name).
4. Choose whether to enrich emails, phones, or both. Only contacts Lusha matches will be charged credits and click Start Enrichment.
5. Lusha processes your file. Depending on the file size, this may take a few minutes.
6. Once complete, click Download to export your enriched CSV.
💡 Tip: The more identifying fields you include in your upload (LinkedIn URL, work email, full name + company), the higher your match rate will be.
7. You can also view the enriched data as a list by clicking View List within the CSV Enrichment dashboard — this automatically creates a new list in the left-hand menu.
8. Download the enriched list by clicking the three dots (⋮) next to the list name > Export to CSV.
How to manage your enriched CSV files
Any CSV file you enrich can be accessed through the Enrich tab for 3 months. To remove a list, click the trashcan icon to confirm deletion.
💡 Note: After 3 months, you'll only be able to access the enriched data through the created list, which can be exported to a new CSV file.
Credits and costs
Each successfully enriched contact costs 1 credit. Rows that are not matched do not use credits.
💡 Note: Credits are only consumed when Lusha finds and returns verified data for a contact. Unmatched rows are free.
🛠️ FAQs
What's the difference between Enrich and CSV Enrichment?
They are the same workflow. "Enrich" is the name of the page in the dashboard. "CSV Enrichment" refers to the file-based method. Both point to the same place.
Can I enrich company data only, without contacts?
Yes. Map your company name and/or domain and Lusha will return firmographic data (industry, size, revenue, HQ location) for each company row.
What happens to rows Lusha can't match?
Unmatched rows are included in your download with the original data intact and the enrichment columns left blank. No credits are used for those rows.
Is there a row limit per upload?
Yes, each plan has a different row limit per enrichment:
Free — 100 rows
Professional — up to 300
Premium — up to 500
Scale — up to 10,000.
You can enrich as many files as your credits allow.
