I need a clean, reliable database of 100,000 email addresses belonging strictly to UK-based construction contractors, sub-contractors and related businesses. Every address has to be live and deliverable, with verification carried out through Mailgun so the final bounce rate stays well below two percent. The file must be delivered in CSV format and, besides the email itself, each record must also hold the company name, its location (city or county is enough) and a short trade / industry label that tells me whether they handle groundworks, roofing, fit-out, M&E, etc. No duplicates and no generic “info@” style inboxes, please—only contacts that decision-makers actually monitor. To keep everything compliant, source the data from publicly available material and follow UK GDPR guidelines; I will need a brief note on where and how the information was gathered. Deliverables • CSV containing 100,000 rows with the four required columns • Mailgun verification report or screen capture proving status for the entire list • One-page sourcing & compliance summary I will review a small sample first for quality, then release the milestone once the full dataset meets these standards.

Hello, I’m Jordan Rafael. I understand you’re seeking a clean, reliable database of UK-based construction contractors with verifiable, deliverable emails and a clear, compliant sourcing trail. I propose a phased, transparent approach that prioritizes data quality, compliance, and practical deliverability over sheer volume. Phase 1 will deliver a representative sample (5,000-10,000 records) with company name, location, and a trade label, all verified for deliverability and sourced from public, opt-in and publicly listed channels with documented provenance. Phase 2 scales to the full 100,000 records, applying strict filters to exclude generic inboxes and duplicates, and exporting to CSV with the four required columns: Email, Company, Location, Trade. Each record will be cross-verified via a reputable validation service and supplemented with a verifiable sourcing note. Deliverables will include the CSV, a Mailgun verification report (or screen captures showing deliverability status), and a one-page sourcing & compliance summary. I will maintain a clear audit trail documenting data sources, dates, and methods to ensure UK GDPR alignment. While every email’s deliverability at scale is challenging, I will implement robust cleansing, deduplication, and ongoing validation to minimize bounce rates well below 2%. I’ll also provide a concise note on data collection methods, consent considerations, and usage constraints. I’m happy to adjust scope, timing, and cost after a brief sample re
