What's Inside the Free Sample CSV

August 31, 2026

Every category in our directory offers a free, downloadable CSV sample. We believe in complete transparency before you consider ordering a custom dataset, so you can inspect data accuracy, coverage, and field structures firsthand.

Here is an exact, field-by-field breakdown of what you receive in every sample download.

Contact Enrichment & Demo Verification

To protect personal privacy while validating data authenticity:

  • Unmasked Demo Rows: Each sample includes verified demo records with real executive names and direct emails. You can send test emails to verify deliverability and inbox placement before purchasing.
  • Masked Standard Rows: Remaining rows show masked email patterns (such as d.m****@domain.com) alongside executive job titles, confirming that verified contacts exist for those accounts.
  • Full Datasets: When you order a custom dataset, all verified contact names, direct emails, and executive phone extensions are delivered 100% unmasked.

Data Completeness & Digital Footprint

Real-world commercial data is not uniform. We score every listing based on 8 primary contact channels: website, business email, web contact form, LinkedIn, Facebook, Instagram, Twitter, and direct phone.

  • Top Tier (~8% of records): Complete digital footprint with 7 or 8 active contact channels.
  • Core Tier (~35% of records): Robust presence with 4 to 6 channels (typically phone, website, business email, and LinkedIn).
  • Baseline Tier (~57% of records): Local presence with 1 to 3 channels (primarily physical address and main phone line).

Deterministic Sampling: Our samples are drawn using a stable pseudo-random algorithm across the entire category. We never cherry-pick only the most complete profiles — what you see in the sample represents the true quality distribution of the database.

Limits & Download Security

Fair Use Policy:

  • Daily Allowance: Up to 3 free samples per registered account per 24-hour period.
  • Instant Delivery: Download links appear in your Account dashboard as soon as the background export finishes (usually under 30 seconds).
  • Security: Each link is cryptographically tied to your authenticated account, works once, and expires after 7 days. Links cannot be shared or forwarded.

Opening and Inspecting the File

Every sample includes a standard UTF-8 Byte Order Mark (BOM). This ensures that Microsoft Excel, Google Sheets, and Apple Numbers open the file cleanly with proper columns and character formatting without requiring import wizards.

Inspecting with Python (Pandas)

import pandas as pd

# Load sample dataset
df = pd.read_csv('prospectlist-roofing-contractors-sample.csv')

# Inspect total records and available contact channels
print(f"Total companies: {len(df)}")
print(f"Companies with website: {df['website'].notna().sum()}")
print(f"Companies with business email: {df['business_email'].notna().sum()}")
print(f"Companies with social profiles: {df['linkedin'].notna().sum()}")
