Overview
卖家之家 is not product-research SaaS and not Amazon’s official risk engine. It is Fuzhou seller media whose slogan moved from “read news, check reviews, use tools” to “read news, check reviews, find services,” at mjzj.com. In 2026 the first click is usually a search for a reviewer’s WeChat, email, or Amazon profile — not a policy feature. The check-review page claims about 303,000 blacklist names. That is a user-submitted corpus, not a court docket.
News ships on PC, mobile web, app, mini program, and WeChat / Channels / Douyin / Xiaohongshu. The about page (April 2026 copy) cites 350,000+ site users, 300,000+ WeChat followers, 40,000+ short-video followers, 2 million+ professional reach, 600+ vendors, an Agent skill at mjzj.com/skill.md, and an international site heycross.com. Those figures are vendor claims and unverified. The operator is 福州数析信息科技有限公司, founded in 2015. English Reddit does not discuss the site.
Core features and advantages
The 测评 blacklist
The review blacklist is the wedge. Search by name, WeChat, email, Facebook, or Amazon profile; you can also file an exposure post. Non-VIP search is tightly capped (the benefits table: 10 / day for ordinary and real-name users, 100 / day for VIP, 400 / day for SVIP). SVIP can batch-query (max 10 per run) and export history. Concrete use: before you pay an off-Amazon reviewer, paste the WeChat ID and email. A hit is not a police finding; it is often enough to switch to Vine or walk away. Appeals are in-site “我要申诉” only — email appeals are refused.
News and omnichannel distribution
The home feed covers Amazon, TikTok, independent sites, Southeast Asia, AI. Many pieces are republished from 雨果网, AMZ123 flashes, and outside authors. The WeChat subscription account is the morning paper; the website is the search and posting console. Do not treat a reprint as 卖家之家 exclusive reporting.
Find-a-vendor, supply posts, and VIP quotas
Popular vendors, product boards, supply-and-demand, Q&A, events, and an academy sit in the second half. VIP/SVIP raise post, refresh, DM, and search quotas and can show a WeChat QR. That is classified ads, not an ERP. This catalogue also has 测评黑名单, an older landing page for the same feature.
Supported platforms
The media is for China-origin exporters, Amazon-first, with TikTok Shop and independent-site coverage. Product surface: mjzj.com, mobile web, app, WeChat mini program, official accounts, plus heycross.com. You use it as a browser blacklist check plus WeChat news, not as a Seller Central plugin.
Who it's for
- Solo Amazon sellers who pay off-platform reviewers. Start with the free quota; buy VIP if you run out.
- Small teams that need SVIP batch export when one VIP seat is not enough.
- Vendors posting supply cards, within real-name and no-spam rules.
- Skip it if you never buy 测评, if you do not read Chinese, or if you think a blacklist hit equals a criminal conviction.
Pricing and value
News is free. You pay for search quota and community privileges. Rechecked 2026-09-06 promo prices: VIP ¥69 / month (was ¥99), ¥588 / year (was ¥1,188); SVIP ¥199 / month (was ¥299), ¥1,988 / year (was ¥3,588); real-name verification ¥28 / time (was ¥39, valid one year, includes 10 days of VIP). Promos move; confirm on the pay wall.
If you only search a few times, use the free cap. Buy an annual plan only if 测评 outreach is a weekly workflow. Non-VIP nicknames and posts may not carry contact details.
Community feedback
Chinese sellers treat “search it on 卖家之家” as the verbal checklist before paying a reviewer. They also know the corpus is crowdsourced: misses, false flags, and people who change WeChat IDs and run the same scam. Public group WeChats are mjzj333 and maijiazhijia888. Tips contact@mjzj.com, complaints complain@mjzj.com, sales anchor@mjzj.com. No useful English-community thread.
Competitive positioning
The moat is the reviewer corpus, not newsroom depth. AMZ123 also links a blacklist, but it is a bookmark portal. 雨果网 is stronger on policy copy. 跨境知道 lets you debate a rule in-thread. None of them replace Vine or Amazon’s official review policy.
Alternatives
- AMZ123 — Seller Central shortcuts, freight directories, headlines.
- 雨果网 — policy long reads and 雨课.
- 跨境知道 — K-circle how-to posts and reports.
Limitations
The blacklist is UGC and can be stale or malicious. Search caps put the core job behind a paywall. News is heavily syndicated. Vendor user counts are unverified. The site does not tell you whether a listing violates policy and does not give legal advice. Warehouse and freight modules are ads.
Verdict
In 2026 China Amazon sellers should still bookmark 卖家之家: use the web for 测评 checks, WeChat for the paper. Do not treat a hit as a police result, and do not buy SVIP just to spam.
Next step: open mjzj.com and run one free search on a counterpart. If the quota is gone, check live VIP/SVIP promo prices. Follow the official account for news.
