deliverability-qa
技术性强，可在发信前发现致命送达与声誉问题。
需要查询DNS和可能使用种子地址/外部检测服务，涉及凭据与外部调用。
做发送前的送达率与认证（SPF/DKIM/DMARC/BIMI）及收件箱分布检测。
发邮件前做一次全面的送达率体检：检查 SPF/DKIM/DMARC/BIMI 认证、域名和 IP 的声誉、收件箱投放位置、内容/链接会不会被判为垃圾，以及发送时点的退回/投诉情况。适合在大规模发信或重要活动前跑一次，避免直接进垃圾或被运营商降分。结果以每项 Pass/Partial/Fail/Unknown/N/A 展示，并打出 S1 认证证据标记，给出一次性的发送端交付能力快照。

Use when the user asks to "run a deliverability pre-flight before I send", "check my SPF/DKIM/DMARC/BIMI", "why am I landing in spam / promotions", or "score my sender reputation and list hygiene"; runs the ONE-TIME pre-send SEND S1 authentication pre-flight and builds the SEND S (Sender-integrity / Deliverability) evidence read — DNS + DMARC-RUA auth, domain/IP reputation, inbox placement, content/link/render, and point-in-time bounce/complaint hygiene — using Pass/Partial/Fail/Unknown/N/A states and scoring only at complete applicable coverage. Not for the recurring hygiene trend — use list-hygiene-monitor; not for final EQS or veto verdicts — use email-quality-auditor; not for segments/suppression lists — use list-segment-builder. 邮件送达率预检/SPF DKIM DMARC认证/发件域声誉
