What this means
Anyone can open an inbox at zj-trade.com, so an address there says nothing about the company the person works for. That makes it a personal email, even when someone uses it for work. It is on our free email providers list.
isBusinessEmail returns category "personal": block under the b2b and strict policies, allow under lenient. zj-trade.com receives mail through hzmx01.mxmail.netease.com, hzmx02.mxmail.netease.com.
Questions about zj-trade.com
Is zj-trade.com a business email?
No. zj-trade.com is a shared email provider, so isBusinessEmail classifies it as "personal". A business email uses a domain the company owns.
Is zj-trade.com a free email provider?
Yes. zj-trade.com hands out inboxes on its own domain to individuals, which is what makes an address there a personal email.
Should a B2B product accept zj-trade.com sign-ups?
It depends on what you need. If you need a company tenant or a company to sell to, ask for a work email; if you only want real people, accept it. The b2b policy blocks personal addresses and the lenient policy allows them.
How can I tell zj-trade.com apart from a company domain in code?
POST the address to /v1/check: shared providers come back with category "personal" and is_free_provider: true, company domains with category "business".
