I need an experienced specialist who can both build an international B2B email list and run a high-volume cold-email sequence that reliably lands in the primary inbox. Scope • Regions: North America and Europe are the core focus, with South America included as well. • Industries: The brief is intentionally broad—any sector is valid as long as the contacts align with HR strategies and decision-making roles. • Company size: Small businesses through to large enterprises are all in scope. Objectives 1. Scrape and enrich a fresh, GDPR-compliant database. 2. Design the sending infrastructure—servers, IP warming, domain rotation, tracking, and deliverability safeguards—to scale smoothly to 10 000 emails per day within six weeks. 3. Write, schedule, and optimise multi-step email sequences (intro, follow-ups, break-up). 4. Monitor and tweak for deliverability, open rates, and conversions in real time. Acceptance criteria – Minimum 95 % delivery rate and sub-2 % bounce rate once fully scaled. – Clear daily and weekly performance reports. – All data supplied in CSV plus access to the sending platform for verification. If you already have the hardware or a proven cloud setup for high-throughput email, tell me briefly what you use; otherwise outline the stack you propose. I will move quickly once I see evidence of past results at comparable volume.

Hello, "Scalable Cloud Email Sending Stack" - need to deliver 10k emails daily with high inbox placement. I will use AWS EC2 with dedicated IP pools and Mailgun for deliverability, because it scales and offers built‑in warm‑up tools. I built a similar B2B lead list for Polish dental clinics, delivering clean CSVs: https://www.freelancer.com/projects/data-collection/Polish-Dental-Clinics-Business-Leads/reviews. I will ensure GDPR compliance by validating consent and using double‑opt‑in verification, and I will set up real‑time monitoring to keep bounce rates below 2%. Do you have existing domains you want to use, or should I provision new ones for the sending infrastructure? Looking forward to working with you. Artur Giżycki

You're building Global B2B Email Scraping & Outreach, where the real delivery risk is usually in the workflow details, not just the feature list. I have handled similar systems where the important part was turning a broad brief into a reliable working version. My approach would be to first define the integration contracts and backend boundaries, then deliver the first milestone around the riskiest data flow instead of only UI screens. For this project, I would focus especially on: - core workflow risks and acceptance criteria - integration points and edge cases - milestone planning and handover clarity If helpful, I can outline the first milestone around the riskiest part of the build before we start. Best, Dr. Syafiq

Hello, I will build a GDPR compliant international B2B contact database and deploy a deliverability safe cold email system that scales to 10,000 sends per day. I will scrape with Puppeteer and custom parsers, enrich contacts via Clearbit and NeverBounce verification, normalize data to CSV and retain consent and source metadata for GDPR audits. For sending I use a hardened cloud stack on Hetzner VPS clusters running Postfix with OpenDKIM and OpenDMARC, dedicated IPs with staged warming, domain and subdomain rotation, Mautic for sequence orchestration, and Grafana for real time deliverability monitoring and alerts. I ran a comparable setup that reached 12,000 daily sends with 95 percent delivery and under 2 percent bounce. I will supply CSV exports, platform access for verification, and clear daily and weekly reports. If you share a short target domain list I will deliver a free 48 hour deliverability and list readiness report with actionable fixes. Happy to jump on a quick chat. Ali Zain
