How many contacts can I process at once?

You can process between 2 and 30 contacts per batch. Upload a CSV file or paste your LinkedIn URLs manually.

Yes. You get 1 free bulk search per email address. No credit card required. This helps you evaluate the quality of bulk mobile enrichment before committing to a paid solution.

Which providers are used?

We use 4 leading data providers: Prospeo, LeadMagic, FullEnrich, and Findymail. Each has different data sources and coverage strengths, which is why combining them via waterfall gives the best results.

What CSV format should I use?

Your CSV should have a linkedinUrl column (required). Optionally include firstName, lastName, and company columns. The tool auto-detects headers and delimiters.

Why do I need LinkedIn URLs?

Phone number providers require LinkedIn profile URLs to identify contacts and look up their phone numbers. This is the most reliable way to match people to their direct phone numbers.

Can I download the results?

Yes. Once the enrichment is complete, you can download a CSV with all results including linkedinUrl, name, company, phone, provider, and confidence score.

What if some contacts are not found?

Contacts that aren't found by any of the 4 providers will be marked as "not found" in the results. Phone numbers are harder to find than emails, so expect a lower hit rate.

Step 4

How bulk mobile waterfall enrichment works

The tool uses a bulk waterfall enrichment approach: each data provider processes all unfound contacts before falling through to the next provider. This is much faster than running individual lookups.

FullEnrich processes contacts in a single batch API call. Other providers process contacts with parallel concurrency for speed. Each provider only searches contacts that haven't been found yet.

This approach maximizes phone coverage while minimizing time. The provider order is optimized based on our testing: Prospeo, LeadMagic, FullEnrich, and Findymail.
