Country / State / City (if available)
Additional Notes:

The database must be real and up to date (2024–2025) — no fake or outdated records.

The emails must be verified and active (use of tools like Hunter.io, NeverBounce, or Apollo.io preferred).
Minimum 5,000 verified contacts (larger datasets welcome).
Delivery format: CSV or Excel (.xlsx).
Please include a short sample (20–30 rows) to verify data quality before final approval.

Deliverables:

CSV/XLSX file with at least the above columns.
Short report on how the data was sourced and verified.

Budget:
