Playbook Warm Intros

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.

• Member 2's source probe passed — 20/20 rows carried a dated matched past experience, a profile URL and a city, and 15/20 had moved on.
• Member 5's source probe passed — the investor filter returns a real result count.
• No member has produced a graded warm_intro_line.

Everything below §3 is a build spec, not a measured path. Treat the coverage and quality claims as unverified until you run one.

1. A family, not one playbook

A warm-intro signal is any evidence that the prospect is already one hop from the client, so email 1 can lean on a real connection instead of a cold pitch.

Seven members share the copy shape warm_intro_line. They do not share a data source. So this is one routing table plus one build recipe per member.

Why member 1 was reframed, and why it matters

Member 1 originally meant "overlapped in time with someone on the client's team". That list is always too small, and it never once got run.

Reframed, it means everyone who ever worked at the case-study company and has since moved on — which is a large, buildable list from the same source as member 2.

The general lesson: a warm-intro definition that requires a time overlap between two specific people produces a list too small to campaign on. Widen to "worked there at all, and left" and the same data source suddenly supports a real segment.

2. Output contract

Abstain value: "".

Keep the member field. Seven members share one copy shape, and without it you cannot tell later which angle actually produced replies — which is the only way this family gets narrowed to the two or three members worth keeping.

⛔ Never name a real third party in copy without permission

The line says "who we work with now", not "we work with Coca-Cola" — unless the client has explicitly approved naming that customer.

Naming a client's customer in cold email is the client's decision, not yours, and it is the fastest way to turn a clever campaign into an awkward phone call. Default to the unnamed form.

Note this is the same posture playbook-lookalikes takes with case-study companies, for the same reason.

3. Build member 2 first

The source is a people search with a past-company filter set to the client's customer or case-study companies.

What the probe confirmed on 20 rows:

• a dated matched past experience,
• a profile URL,
• a city,
• and 15 of 20 had moved on — which is the population you actually want.

That last number is the one to plan from. Roughly three quarters of "ever worked there" is "worked there and left", and the rest are current employees who must be excluded (they are the customer's staff, not prospects).
