Use when the user asks to "design an email A/B test", "set up a multivariate subject/CTA test", "run a send-time test", "build a hold-out group", or "is this email result statistically and practically material?"; produces a falsifiable hypothesis, one-variable-per-cell matrix, sample-size/MDE/duration/power plan, and an effect/uncertainty read from own ESP data. Applies only a precommitted owner-approved action rule; the helper never chooses a business action. Not for EQS/vetoes or writing the email. 邮件AB测试设计/多变量测试/发送时间测试/留出组/显著性判定

# Send Experiment Designer Designs email experiments across four modes and reads them out: a falsifiable hypothesis, a variant matrix that isolates **one** variable per cell, a sample-size / minimum-detectable-effect / run-duration / power plan, and a documented effect/uncertainty read. It may apply an owner-approved precommitted action rule, but statistical output alone never chooses a business action. **Mode set (pick one):** | Mode | Isolated variable | Primary metric | |------|-------------------|----------------| | `a-b` | one change — subject *or* preheader *or* CTA *or* creative | open (subject) / click / CTOR (CTA/creative) | | `multivariate` | 2+ factors crossed (e.g. subject × CTA), one variable per cell | the goal metric, powered per cell | | `send-time` | deploy hour/day; subject, segment, creative held constant | same-window engagement (open/click) | | `hold-out` | send vs no-send (randomized control receives nothing / current default) | conversion or revenue-per-recipient (incremental lift) | Default the mode from the request when it is unambiguous (e.g. "test two subject lines" → `a-b`, "best hour to send" → `send-time`, "measure incremental revenue" → `hold-out`); s

How do I install it?
Run `npx skills add aaron-he-zhu/aaron-marketing-skills --skill send-experiment-designer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From aaron-he-zhu/aaron-marketing-skills, a repository with 2,508 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
