CSV Enrichment: How to Enrich a Contact List in Minutes
You have a CSV with names and companies but missing emails, phones, or job titles. This guide shows you how to enrich it — no technical setup, no API keys, results in minutes.

CSV enrichment is the process of taking a spreadsheet of contacts or companies and automatically adding missing data fields — like professional email addresses, direct phone numbers, job titles, LinkedIn URLs, company size, tech stack, and more. You upload your file, an enrichment engine looks up each row in real time, and you download a new file with the added columns.
For sales teams, CSV enrichment turns a raw export from LinkedIn, a trade show badge scan, or a website contact form into a fully qualified prospect list — ready for outreach, segmentation, or CRM import — without manual research.
The key difference between tools is data source: older platforms (Apollo, ZoomInfo) query a pre-built database that may be months out of date. Enrich-CRM performs live lookups at query time, so the data reflects the contact’s current role and employer — not their position from six months ago.
What data can you add to a CSV?
Enrich-CRM supports enrichment on both contact-level and company-level fields. All lookups are real-time — no stale database.

How to enrich a CSV in 4 steps
Prepare your CSV
Your file needs at least one identifying column per row. Accepted identifiers: domain, email, linkedin_url, or first_name + last_name + company. You do not need all of them — one strong identifier per row is enough. Remove duplicates and empty rows before uploading. Maximum file size: 50,000 rows.
Upload your file in Enrich-CRM
In app.enrich-crm.com, go to File Enrichment → Upload CSV. Select your file (CSV or Excel). Enrich-CRM auto-detects your column headers and maps them to the correct input fields. Review the mapping — you can correct it manually before starting.
Choose which fields to enrich
Select which output columns you want added: contact fields only, company fields only, or both. Each enriched row consumes 1 credit. Rows where no data was found are not charged. You can preview the estimated credit cost before confirming.
Download the enriched file
Processing runs in the background. You receive an email when it’s done. The enriched file has all your original columns plus the new fields added at the right. Match rate, confidence scores, and empty fields are clearly labeled so you can filter by quality before importing to your CRM.
Common use cases for CSV enrichment
Outbound prospecting list
Export leads from LinkedIn Sales Navigator, a scraper, or a trade show. Upload the CSV to add work emails and direct dials before handing the list to the sales team.
CRM database cleanup
Export stale CRM contacts to CSV. Enrich to refresh job titles, emails, and company data. Re-import the clean file. Eliminates the 30% annual decay in B2B databases in one batch operation.
ICP scoring enrichment
Add company headcount, funding stage, tech stack, and revenue range to a contact list for ICP scoring. Feed the enriched CSV into your scoring model or segment it before CRM import.
Why real-time enrichment matters for CSV files
Most enrichment tools query a static database. If a contact changed jobs six months ago, you get their old title and employer. For outbound sales, this wastes calls and burns sender reputation.
Enrich-CRM performs live web lookups for each row at the moment of enrichment — not a cached database snapshot. This means the job title, company, and email returned reflect the contact’s current situation.
Static database tools (Apollo, ZoomInfo)
- • Data refreshed every 30-90 days
- • Job titles may be 6+ months stale
- • Bounceback risk on exported emails
- • US-centric coverage for EU contacts
Enrich-CRM (real-time)
- • Live lookup at enrichment time
- • Current role and employer always
- • Email confidence score per row
- • Strong EMEA coverage, GDPR-native
Frequently Asked Questions
How many rows can I enrich at once?
Enrich-CRM supports files up to 50,000 rows per upload. For larger databases, split the file and upload in batches. There is no limit on the number of uploads per month.
What file formats are accepted?
CSV (comma-separated, UTF-8) and Excel (.xlsx) files are both accepted. If your CSV uses a different delimiter (semicolon, tab), select the delimiter in the upload interface before processing.
What is the match rate for CSV enrichment?
Match rates vary by input quality and geography. With a domain or professional email as identifier, company enrichment typically reaches 85–95%. Contact enrichment (email find, direct dial) reaches 60–80% for European contacts and 70–85% for US contacts. Rows with no match are not charged.
Is enriched data GDPR-compliant?
Yes. Enrich-CRM only sources publicly available professional information. All processing occurs on AWS eu-west-3 (Paris). No data is transferred outside the EU. A full DPA is available on request. You remain the data controller for the records in your file.
Can I import the enriched CSV directly into HubSpot?
Yes. The enriched file is formatted with clean column headers ready for CRM import. For automatic sync without manual CSV steps, Enrich-CRM also offers a native HubSpot integration that enriches contacts directly in your CRM without any file handling.
