Relationship
The Email Playbook
What this build is for
Email reaches people who already know you, with the one thing they need next, in words they can forward.
It's the oldest channel in this playbook and the most misused. Most firms run it as a broadcast: a newsletter on a schedule, a promotion when sales are slow, a sequence for every download. That reaches everyone and answers no one. This playbook runs it the other way: a message exists only because someone, at a known moment, has a question it answers.
Email belongs to the Relationship category: your system, talking to people you already know. That gives it two jobs. Inside a relationship, it keeps the people around a deal or a review informed at the moments they'd otherwise wonder: is it on track, are the savings real, what happens next. Around the relationship, it keeps Kestrel's thinking in front of people who aren't buying yet, through a newsletter worth reading, cut from Content's core pieces.
Email writes every message other builds send. Automation decides when a message goes; the pitch decides what goes in the proposal; Customers decides when to ask for a referral. The words come from here, written once, in the brand's voice, checked against Credentials.
The footprint, and what it reads from the chain
In Kestrel's map, email leads 3 cells and 3 moments, all during and after the review, where a busy executive needs to know without asking:
| Moment | Who | Their question |
|---|---|---|
| Delivery | COO | "Are we on track, and what are they finding?" |
| Delivery | Finance director | "Are the savings real, and are they being counted properly?" |
| Extend and refer | Finance director | "Are the savings showing in the accounts?" |
It supports 14 more cells, among the widest support of any build: the business case moments for the COO, owner and finance director (7 of them), the investor's trigger, week zero and the plant manager's weekly tasks, the follow-on for the COO, owner, plant manager and investor, and the improvement lead's delivery and next review. In almost all of them, another build decides the moment and email carries the words.
What it reads, and never rewrites:
| From | It takes |
|---|---|
| Identity | The voice, and the words to use and avoid |
| Credentials | Every claim and figure a message states |
| Where you stand | Which moment each message serves, and the chooser's question |
| Content | The core pieces the newsletter is cut from |
| The pitch and Automation | When each message goes, to whom, and what happens on a reply |
Its slice of the Score, and its own audit
Email's part of the Selectability Score is Answered and Believed at the moments after the signature: does the COO know how it's going, and does the finance director believe the savings?
| Kestrel today, the 3 moments email leads | Answered | Believed | Preferred | Bought | Moment score |
|---|---|---|---|---|---|
| COO · delivery | 75 | 80 | 80 | 75 | 78 |
| Finance director · delivery | 45 | 50 | 70 | 65 | 57 |
| Finance director · extend | 40 | 45 | 60 | 50 | 49 |
The pattern is clear: Kestrel keeps the COO informed and leaves the finance director to guess. The COO hears from the engineers on site; nobody writes to the finance director until the invoice. Yet the finance director decides the next review, and their "are the savings real?" is the question every future proposal has to answer.
The audit.
| What Kestrel sends today | To whom | What it misses |
|---|---|---|
| Engineers' weekly notes, each in their own format | The COO, sometimes | The finance director; a consistent record of findings and savings |
| A final report | The COO | A plain summary the finance director can check against the accounts |
| Nothing after the review | — | The 90-day check; the programme decision; the referral |
| A quarterly newsletter of firm news | 1,400 contacts, all of them | Any question a reader has. Opened by 14%, answered by none |
The newsletter is the same mistake as the old blog: it exists because a calendar said so.
Step 1: the shape, the lifecycle programme
Email's shape is the lifecycle programme: the streams of messages a relationship goes through, from first contact to the next piece of work. Every category has the same skeleton; what changes is how long each stream lasts and who reads it.
| Stream | When it runs | Who it's for at Kestrel | In the category (of 5 firms) |
|---|---|---|---|
| Welcome | After a first enquiry or download | Whoever asked | 4 |
| Newsletter | Regularly, to people not yet buying | COOs, finance directors, improvement leads, investors | 5 |
| Deal | From fit call to signature | The buying group | 2 |
| Onboarding | Signature to week one | Plant manager, improvement lead, procurement | 1 |
| Delivery | Each week of the work | COO, finance director, plant manager | 1 |
| Results and renewal | After the work | Finance director, COO, owner | 0 |
| Re-engagement | When a past client might need more | COO, procurement, investor | 1 |
Canon is just the welcome and the newsletter: everyone does them, so their absence would be noticed. The opening is in the streams almost nobody runs: delivery, results and renewal. That's where Kestrel's moments are, and where its competitors leave the finance director guessing.
Step 2: coverage, one message per question at each step
The coverage unit is a message per question per step. For each of the 17 cells email leads or supports, take the chooser's question and ask: is this answered best by a message arriving on its own, at the right moment? If yes, it gets a message.
| Stream | Moments | Messages |
|---|---|---|
| Welcome | Investor trigger; any enquiry | 2: an acknowledgement with a next step; for investors, the portfolio note |
| Newsletter | Trigger and framing, for four choosers (supporting Content) | 1 a month, cut from the core pieces: 12 a year |
| Deal | COO, owner and finance director building the case (9 moments) | 3: the business case kit with their figures; the board paper; a note before the board meets |
| Onboarding | Plant manager and improvement lead · buying; improvement lead · scope | 3, written here, sent by Automation's week-zero flow |
| Delivery | COO, finance director and plant manager · delivery; improvement lead · delivery | 3 a week for six weeks: Monday tasks, the Friday update, the finance director's savings tally |
| Results and renewal | Finance director, COO, owner, plant manager · extend | 4: the results summary; the 90-day check; the programme note; the referral ask |
| Re-engagement | Investor and improvement lead · extend | 2: the portfolio note; "running the next review yourselves" |
That's 14 messages written once, three weekly templates, and a monthly newsletter. Every message has a moment; none is there because a sequence needed a fourth email.
Step 3: gaps, biases and jobs
| Moment | Stage | Bias | The job |
|---|---|---|---|
| Finance director · delivery: "Are the savings real?" | Believed | We follow others | A weekly savings tally from week three: each finding, its value, how it was counted, and who on the client's side agreed it |
| Finance director · extend: "Are they showing in the accounts?" | Believed | Losses loom larger | The 90-day check: the finding, the figure, a single question, "does this match what you see?" |
| COO · delivery: "Are we on track?" | Answered | A hard choice stalls | One Friday update in one format: what was found, what changed, what's next, what's needed from them |
| Plant manager · delivery | Answered | A hard choice stalls | Monday tasks short enough to read on the floor; SMS if they prefer |
| COO, owner and finance director · building the case | Believed | Losses loom larger | The kit and the board paper sent with a covering note in each reader's terms, not one note for all |
| COO · extend: "Do we go into the programme?" | Preferred | A hard choice stalls | The results summary with the programme's cost and its likely return, side by side |
| Owner · extend: "Would I tell another owner?" | Preferred | We follow others | The referral ask, only after confirmed savings, made easy: one forwardable paragraph |
| Every newsletter reader | Known | Familiar feels safe | A newsletter that answers one buyer question a month, from Content's pieces; firm news moved to a short footnote |
The biggest gap is one person. The finance director is written to at none of the moments where they decide what Kestrel is worth.
Step 4: reconcile, the email plan
| Stream | Messages | Moments | Sent by | Signals | Priority |
|---|---|---|---|---|---|
| Delivery | Friday update; finance director's savings tally; Monday tasks | 4 | Automation (review rhythm) | Coverage, strategy | P1 |
| Results and renewal | Results summary; 90-day check; programme note; referral ask | 4 | Automation (savings confirmation, programme decision) | Coverage, strategy | P1 |
| Deal | Kit cover note per reader; board paper note; pre-board note | 9 | The deal owner, from the pitch | Coverage | P1 |
| Onboarding | Week-zero messages to plant manager, improvement lead, procurement | 3 | Automation (week zero) | Coverage | P2 |
| Newsletter | One a month, cut from Content | 4 choosers' trigger and framing | Marketing lead | Canon, coverage | P2 |
| Welcome | Acknowledgement; investor portfolio note | 2 | Automation (enquiry response) | Canon | P2 |
| Re-engagement | Portfolio note; "running the next review yourselves" | 2 | Automation (re-engagement) | Coverage | P3 |
Every moment email leads or supports has a message; every message has a sender. The two P1 streams are the ones no competitor runs.
Rejected, with reasons:
- A five-email sequence after every download. Nobody downloading a cost article is waiting for five emails. One acknowledgement, then the newsletter if they ask for it.
- Promotional emails. Kestrel has nothing to discount, and no moment asks for an offer.
- The firm-news newsletter. Replaced. News survives as two lines at the foot of the monthly issue.
- Personalisation by first name only. It answers nothing. Personalise by role and moment, or not at all.
The anatomy library
| Message type | Parts, in order | Length |
|---|---|---|
| The update (Friday, delivery) | Subject: the week and the headline finding · What we found · What changed on the floor · What's next · What we need from you, if anything | Under 200 words |
| The tally (finance director) | The running total, with its range · Each finding: value, how counted, who agreed it · What isn't counted yet, and why | A table and three lines |
| The check (90 days) | The figure we said · One question: does it match? · How to reply in one line | Under 100 words |
| The cover note (deal) | The reader's question, answered in the first line · What's attached and why it's theirs · The one thing to do · Who to call | Under 120 words |
| The ask (referral) | What was achieved, in their figures · The ask, specific: one person, one call · A paragraph they can forward · An easy no | Under 150 words |
| The newsletter issue | One buyer question, in the subject · The answer, in the first paragraph · One figure, sourced · A link to the full piece · Two lines of firm news | 300 to 500 words |
Five rules hold for every message:
- It comes from a person, by name, who will read the reply.
- The subject line answers or names the question. Never "Update" or "News".
- One thing to do, or nothing. An update with three asks gets none of them done.
- Every figure is signed or theirs.
- It can be forwarded as it is. The COO forwards the Friday update to the board; write it for the board.

The finished example: Hartwell's week four, and the 90-day check, written in full
Three messages from Kestrel's review at Hartwell Plastics, the account from the Pitch Playbook. Hartwell, its people and its figures are invented.
1. The Friday update, week four. To the COO, Lena Marsh; copied to the finance director, Tom Avery.
- Subject: Week 4 at Hartwell: warm-up scrap after changeovers is the biggest loss so far
- Lena, four weeks in, here's where we are.
- What we found. After each mould change on lines 2 and 4, the first 40 minutes of parts are mostly scrap while the tool comes up to temperature. That's nine changes a week, and the largest single source of the 5.8% scrap rate. What changed on the floor. Dave's crew on line 2 trialled pre-heating the next mould during the last hour of the run. Warm-up scrap fell by about two-thirds on the four changes we measured. What's next. The same trial on line 4 next week, and a look at regrind ratios, which drift on night shift. What we need from you. Nothing this week.
- Priya Raman, lead engineer, Kestrel Advisory
2. The savings tally, week four. To the finance director, Tom Avery.
- Subject: Savings found so far at Hartwell: A$185,000 a year (range A$150,000 to A$210,000)
- Tom, this is the running tally, and how each line is counted. A finding only appears here once someone at Hartwell has agreed it.
| Finding | Annual value | How it's counted | Agreed by |
|---|---|---|---|
| Warm-up scrap after changeovers, lines 2 and 4 | A$96,000 | Scrap kg saved × material cost, from your own scrap logs | Dave Okafor, plant manager |
| Regrind ratio drift on night shift | A$58,000 | Virgin material saved at your current resin price | Anna Lee, quality lead |
| Compressed-air leaks | A$31,000 | Metered kWh saved × your tariff | Sione Taufa, maintenance lead |
- Not counted yet: the line 4 trial, until it's measured next week. If any line doesn't match your view, reply and I'll walk you through it.
- Priya Raman
3. The 90-day check. To Tom Avery, 90 days after the review closed with A$214,000 agreed.
- Subject: Hartwell, 90 days on: are the A$214,000 of savings showing?
- Tom, when the review closed in December, we agreed savings of A$214,000 a year, mostly scrap and resin. Three months on, does that match what you see in the accounts?
- A one-line reply is plenty: "yes", "about A$x", or "not yet". If it's not showing, I'd like to understand why, and we'll come back on site to find out.
- Priya Raman
What to notice. Each subject line is the answer. The update is written for the board as much as the COO, because it will be forwarded. The tally counts nothing the client hasn't agreed, which is why the finance director believes it, and why, at 90 days, a "yes" becomes a signed case for the next proposal. And none of the three asks for anything the reader can't do in a minute. Three messages, for one week and one check, at one client.

In the campaign plan
Every campaign has an email moment, usually more than one. The rule: a campaign's emails are written from its core piece and sent to people for whom its question is live, never to the whole list.
| Kestrel campaign | The issue or message | To whom |
|---|---|---|
| The annual benchmark | The newsletter issue on the headline finding; a personal note from a partner to past clients with their sector's figure | Newsletter readers; past clients by sector |
| "Before you buy another line" | The issue "What flat output really costs"; a cover note with the kit for anyone who downloads it | COOs and finance directors on the list |
| Board season | A dated note to finance directors in live deals: the kit, ready for this budget round | Live deals only |
| Owners' round table | The invitation, from the speaker, by name; the write-up afterwards | Owners on the list; attendees |
| Results from the year's reviews | A results issue: what the year's reviews found, confirmed by clients | Everyone on the list, once a year |
Running it
Who owns what. At Kestrel, the marketing lead owns the message inventory, the voice and the newsletter. Every message in a deal or a review is sent in the name of the person who'll read the reply: the deal owner, or the lead engineer. The head of delivery signs the delivery templates; the managing partner signs anything that states the way out.
| When | What happens |
|---|---|
| Weekly, during each review | The Friday update and the tally, checked by the lead engineer before they go |
| Monthly | One newsletter issue, from the content plan; replies read and answered |
| Quarterly | Every template re-read against the claims register and the voice; unsubscribes and replies reviewed |
| When a claim changes | Every message that states it, the same week |
| Yearly | The list cleaned: anyone who hasn't opened in a year is asked once whether to stay |
Permission. Messages in a deal or a review go to the people in it, about it. The newsletter goes only to people who asked for it. Keep the two lists apart, so nobody joins the newsletter because they once signed a contract.
Common mistakes
| The mistake | The stage it breaks | The bias it ignores | At Kestrel | Instead |
|---|---|---|---|---|
| Writing to the champion only | Believed, for the finance director | Losses loom larger | The finance director heard nothing until the invoice | A message to each person whose moment it is |
| Broadcasting to the whole list | Known, worn down | Good enough beats best | Firm news to 1,400 people, 14% opening | One buyer question a month, to people who asked |
| Subject lines that hide the point | Answered | A hard choice stalls | "Update", "Newsletter Q3" | The answer in the subject |
| Counting savings nobody agreed | Believed | We follow others | Totals the finance director couldn't check | Only findings a named client person has agreed |
| Sequences for their own sake | Preferred | Good enough beats best | Five emails after a download | Send what someone is waiting for, then stop |
| Sent from "the team" | Believed | Familiar feels safe | noreply@ on the final report | A named person who reads the reply |
| Asking for the referral too early | Preferred | Losses loom larger | A referral ask in the final report, before any savings showed | After the 90-day check, and only after a yes |
| Messages written in the flow tool | Believed | Familiar feels safe | Terms in an automated email that didn't match the contract | Every message from the inventory, every claim from Credentials |
| Judging by opens | All, unseen | Good enough beats best | A 30% open rate celebrated | Replies, confirmations and forwards to the board |
The bias to watch in the team: the curse of knowledge again, in its email form. The engineer knows what "OEE up 6 points" means; the finance director needs the money.
The business check and the measures
- Revenue: the delivery and results streams protect the next review at every client and make the proof for every new one. If only one stream can be built, build the savings tally and the 90-day check.
- One truth: every figure in every message matches Credentials and the client's own records.
- The offer: the 90-day check asks a question the firm must be ready to hear "no" to. Decide in advance what Kestrel does when savings aren't showing.
- Capacity: the Friday update takes the lead engineer 20 minutes with the template, an hour without it.
| Measure | What it tells you | Stage |
|---|---|---|
| Finance directors who reply to the tally during the review | Whether the savings are being believed as they're found | Believed |
| 90-day checks answered, and the share answered "yes" | Whether results are real, and becoming proof | Believed |
| Friday updates forwarded inside the client | Whether the update is written for the board | Answered |
| Programme or next-plant decisions within 60 days of results | Whether the results stream leads somewhere | Preferred |
| Referrals given after a "yes" | Whether proof turns into the next client | Preferred |
| Newsletter replies per issue | Whether the issue answered a question | Known |
The Loop for this build
Each quarter the Loop (step 11) reads replies and decisions beside the Score's delivery and extend moments, and asks: did the people we wrote to believe the results, and act on them?
| What the Loop finds | What it means | What changes |
|---|---|---|
| Tallies sent, finance directors silent | The tally isn't in their terms, or isn't reaching them | Rewrite in the money and method they use; check the address |
| 90-day checks answered "not yet" | Savings aren't sticking | A Customers job, not an email one: the 90-day visit |
| Results sent, no programme decisions | The results summary doesn't lead to a choice | Put the programme's cost and return beside the results |
| Newsletter opens high, replies none | Issues answer nothing anyone asked | Pick next quarter's questions from sales calls |
| Updates forwarded to boards | The delivery stream is working | Use the format in proposals: "here's what you'll get every Friday" |
What Kestrel's first year would look for. Finance directors replying to the tally during the review, which nobody did last year. Then the 90-day checks: if most say "yes", Kestrel has more confirmed cases in a year than it has in its history, and the finance director's "consultants overstate savings" has an answer in every proposal.
Shapes by business type
| Business type | Typical mode | The streams that usually matter most |
|---|---|---|
| B2B professional services | Committee or owner-led | Delivery updates, results and renewal, a newsletter that answers buyer questions |
| B2B software | Committee | Onboarding to first value, usage and adoption notes per role, renewal and expansion |
| Considered consumer (finance, health, education) | Considered personal | Application progress, plain-language documents, reminders before deadlines, annual reviews |
| Ecommerce | Quick choice or habitual | Order and delivery, replenishment, reviews after use, a few well-chosen offers |
| Local services | Owner-led or considered personal | Booking confirmations, the day-before reminder, a follow-up after the job, seasonal reminders |
| Marketplaces | Varies on each side | Seller onboarding and payouts; buyer order updates; trust and safety notices |
Feeling a bit overwhelmed?
You should be, a little. One firm: seven streams, 14 messages written once, three weekly templates for every review, a monthly newsletter cut from the content plan, every figure agreed by a named person at the client, and two lists that must never mix. Most firms send a quarterly newsletter of their own news and wonder why the finance director never believes the savings.
