email-deliverability-audit
四个依次执行的 DNS 闸门（格式、无效域名、MX、角色邮箱/占位符）将电子邮件地址分类为可发送、有风险或无效，并遵循严格的完整性规则：每个判定都可追溯到该会话中执行的一次查询。
插件会安装到这里；不确定时保持 web。

认领这个 Plugin →Four sequential DNS gates decide whether an email address can actually receive mail — before your campaign finds out the hard way.
四道顺序 DNS 闸门，在邮件发出之前判定一个地址到底能不能收信。
Bounce rates above ~5% push campaigns into spam folders and burn domain reputation. Most list-cleaning tools hand you a score with no evidence behind it. This skill makes the agent run the checks itself — every verdict traces to a DNS query made during that run, and a failed probe is recorded as unverified, never guessed.
退信率超过 ~5%，campaign 就会开始进垃圾箱、烧域名信誉。大多数清洗工具只给一个没有证据的分数。这个 skill 让 agent 自己跑检查——每个判定都能追溯到当次真实 DNS 查询；探测失败就如实记为 unverified，绝不猜。
Gate 1 Format → Gate 2 Dead domain (A/NS) → Gate 3 MX → Gate 4 Role & placeholder
| Verdict | Meaning |
|---|---|
sendable | passed all four gates |
risky | passed gates 1–3; role account or placeholder pattern at gate 4 |
dead | failed a gate in 1–3, with the deciding gate recorded |
Batch mode: CSV in, CSV out, output rows match input rows 1:1. Integrity rule: never invent a pass.
批量模式：CSV 进 CSV 出，输出行与输入行 1:1 对应。诚信铁律：绝不编造通过。
| Address | Verdict | Deciding gate |
|---|---|---|
name@gmail.com | sendable | passed all four |
team@company.com.au | sendable | MX present |
info@shop.com | risky | gate 4: role account |
13800@example.com | risky | gate 4: all-digit local part |
bad@@example.com | dead | gate 1: format |
site@australia.gov.au | dead | gate 3: live website, no MX |
The last row is the gate-3 lesson in one address: a resolving domain with a healthy website can still be unable to receive mail. The site was up; the mail was not.
最后一行就是 Gate 3 的活教材：域名能解析、网站活得好好的，邮件照样收不了——网站在线，收信离线。
