Chinese Machinery Email Sourcing

I need a clean, verified list of Chinese machinery manufacturers that use Alibaba / Aliyun-hosted email accounts. The task is straightforward: search Alibaba.com, supplier pages, and any other reliable sources inside the Alibaba ecosystem to locate active business emails (e.g., …@aliyun.com, …@alibaba.com). Every entry must point to a genuine manufacturer—distributors or retailers are outside the scope. Besides each email address, include the company’s official website so I can review their product catalog later. No additional contact details are required. Deliverables (spreadsheet): • Manufacturer name • Alibaba / Aliyun email address • Company website URL Before submitting, double-check that the email domain matches Alibaba / Aliyun and that the company clearly operates in the machinery sector. Duplicates, generic inboxes that do not belong to a machinery producer, or missing websites will be rejected.
