Individual skill
personalized-outbound-ab-test
Use this skill when someone claims AI personalization lifts reply rates, or before you let an agent write outbound at scale. Runs a control/personalized/holdout split on your connection list, enforces a safety gate on every generated message, and returns a defensible read on whether personalization actually beat the generic baseline.

Run this before you let an agent write outbound at scale. It produces a measured answer to "does personalization actually beat our generic message?" and a holdout that receives the winner.
## The play
1. **Split the list into three.** Control (e.g. 100) gets the generic baseline. Personalized (e.g. 100) gets researched messages. Holdout (the rest) waits for the result, then gets the winner. Without a control you are not testing, you are just spending.
2. **Build the do-not-contact list first.** Exclude anyone already in an open thread, in the CRM as an active deal, or recently sequenced. Skipping this is how you send a "nice to meet you" to a customer. Do this before enrichment so you never pay to research someone you cannot contact.
3. **Enrich only the Personalized arm.** Pull current role, headline, employer, and recent activity per lead. The control arm needs nothing, so half your enrichment spend disappears.
4. **Write one message per lead, then gate it.** Every message must pass all six checks or it silently drops to the baseline:
- **Account-safe** — no links, no phone numbers, no mass-template feel.
- **Factually grounded** — every personal reference traces to retrieved data. Zero invented facts.
- **Human** — no AI tells, in the sender's own rhythm.
