Playbook: Warm Intros

All rules here are best practice, not law. Override any of them when the campaign calls for it; note the best practice once and move on.

Use when: the campaign's whole premise is that the prospect is already one hop from the client, and you need both the list and the line. The strongest version, and the one to build first, is "you used to work at a company that is now our client's customer".

Do not use when: you want a second contact at an account you already email (playbook-name-to-other-prospects), people who engaged with a competitor's or customer's posts (playbook-linkedin-engagement), or companies similar to a seed set (playbook-lookalikes).

One-line output: warm_intro_line = "you came up through Coca-Cola, who we work with now", rendering as Noticed you came up through Coca-Cola, who we work with now.

⚠️ Status: sources probed, no line graded

This is the least proven playbook in the library, and it is written that way deliberately.
