I am assembling a large-scale database of verified business contact emails for manufacturers and suppliers based in mainland China. The exact sector is flexible—electronics, textiles, automotive, or any other industry is acceptable—so long as each record represents a genuine factory or wholesale supplier. What every entry must include is: • A working contact email address • The corresponding city or province within China Extra columns such as company name, product line, phone, or website are welcome bonuses, but the location paired with the email is non-negotiable. Quality matters more than quantity, yet I still need a minimum of 20,000 unique contacts. I will run random bounce checks, so a failure rate above 5 % or noticeable duplication will require a clean-up before final approval. Generic catch-all addresses (info@, sales@) should be limited wherever possible. Please supply the final list in Excel or CSV format. A quick sample of roughly 200 rows early on will let me validate sourcing and move the project forward faster. When you reply, briefly outline your data sources, the verification tools or methods you rely on, and the timeframe you need to compile the full list.

Hey, I’m interested in helping you build this verified database of Chinese manufacturers and suppliers. For sourcing, I plan to use a combination of official company websites, business directories (such as Alibaba supplier listings and Chinese B2B platforms), and verified industrial directories. I will prioritize direct domain-based emails and avoid excessive generic addresses wherever possible. For verification, I typically use email validation tools to check SMTP status and reduce bounce rates before delivery. I also remove duplicates through structured filtering in Excel and run manual spot checks to ensure location accuracy (city/province matched correctly). I can provide a 200-row sample within 2–3 days for your review. For the full 20,000 verified contacts, I would estimate approximately 3–4 weeks, depending on sector spread and validation strictness. I focus on accuracy first, then scale carefully to maintain quality. Suzon

Hi there! Building large, verified B2B databases is exactly where my data-sourcing workflow performs best. I specialize in structured lead generation using multi-source extraction and strict validation layers to ensure accuracy at scale. For this project, I’ll source directly from Chinese manufacturer directories, trade portals, business registries, and verified company websites—then enrich each record with city/province data. Emails will be validated through layered verification tools (SMTP check + bounce-risk scoring) and deduplicated to keep failure rates under 5%. I can provide a 200-row mixed-industry sample early for approval, then scale to 20,000+ unique, cleaned records in Excel/CSV format. Diversified industries and regions are recommended unless you prefer a focused sector.

✔Hello, how are you? I understand you need a high-quality, verified database of at least 20,000 unique business contact emails from mainland Chinese manufacturers and suppliers—with each record including a working email address and city/province, and a low bounce rate below 5%. My expertise in B2B data sourcing and multi-stage verification allows me to compile a clean, targeted list using a combination of Chinese business directories, trade show exhibitor lists, and manufacturer platforms, with email validation tools to filter out generic or invalid addresses. The most critical issue will be ensuring email deliverability and geographic accuracy at scale, requiring rigorous de-duplication and real-time verification to meet your bounce rate threshold. Thank you, Darren.

I’m early in my data research career, but I approach projects with a structured, quality-first workflow. For this assignment, I would source verified manufacturer and supplier contacts from established B2B platforms such as Alibaba, Made-in-China, Global Sources, and trade-fair exhibitor directories, then cross-check company locations using official Chinese business registries. Emails would be cleaned, deduplicated, and verified using professional email validation tools to keep bounce rates below 5%. I understand the importance of pairing every email with a confirmed city or province and can deliver an initial 200-row sample quickly, followed by a well-documented Excel or CSV database.
