CSV Enrichment: What is the right format for the CSV file enrichment?

New Feature: CSV Enrichment Just Got Smarter at LeadDelta

We’re excited to introduce one of our most powerful updates yet — CSV Enrichment via LinkedIn Profile URLs. With just a simple list of LinkedIn URLs, you can now uncover your prospects’ personal email, business email, and even their phone number — directly inside your LeadDelta workspace.

Whether you're enriching 50 or 15,000 contacts, all it takes is one key identifier:
➡️ https://www.linkedin.com/in/username

Yes, that’s it. No names, no company domains, no emails needed upfront. Just paste in LinkedIn profile URLs, and we’ll do the rest.

🧠 Why It Matters

Save time — Skip the manual work of filling in names or guessing email patterns.
Maximize success — Only verified, high-quality contact data is returned.
Boost targeting — Instantly export enriched data into your sales or marketing workflows.
No guesswork — LeadDelta only charges credits for successful finds.

🗂 File Upload Guidelines

To get started, you’ll need to upload a CSV file that meets the following requirements:

✔️ File Format: .csv
✔️ File Size Limit: Up to 5MB
✔️ Max Rows: 15,000 LinkedIn URLs per file
✔️ Encoding: UTF-8 (for special character compatibility)
✔️ One Sheet Only: Multi-sheet files won’t work
✔️ Header Row Required: Include a descriptive column name like LinkedIn URL

👉 Download our sample CSV file and use it as a starting point.

💡 Pro tip: We recommend using Google Sheets instead of Excel to avoid encoding or formatting issues. Once done, simply download your sheet as a CSV and upload it to LeadDelta.

⚠️ Troubleshooting Uploads

If your file:
isn't in .csv format
is too large
lacks a LinkedIn URL column
or includes unsupported encoding
...you’ll see an error message. No worries — just double-check your file using the guide above.

🚀 Ready to Enrich?

Once your file is uploaded, we’ll start enriching each profile. You’ll see real-time progress, and when it’s complete, you can export your enriched data with just a click — ready to be used in CRMs, campaigns, or outreach tools.
