NetEase 163 is an email service operated by NetEase, a Chinese internet conglomerate. It functions as a mail hosting provider (appearing as a primary MX record) for organisations and smaller websites across the global internet, rather than serving as a consumer mailbox platform for individuals.
Within the Tranco top-1 million website dataset, NetEase 163 shows a distinct concentration among smaller and mid-market organisations rather than major global brands, with a predominant .com domain footprint and a global-to-US-skewed regional pattern. Its frequent co-occurrence with Alibaba DirectMail suggests that many organisations using NetEase 163 operate within Chinese or Asian business contexts; for email senders, this means the receiving infrastructure may embody different security policies and operational assumptions than Western-dominant providers.
