Most campaign briefs start broad. Run your business better, save time on admin, grow faster. Each of those is true for your product, and each one is true for every competitor too, so the buyer reads past it.
The sentence that would make the same buyer stop is usually already inside your company. It sits in three places your marketing team can read today: sales calls, support tickets and the notes customers leave when they cancel. This post is the method for finding it, step by step. It needs no new tool and no research budget, only access to those three sources and a day of reading.
What makes a campaign angle specific?
Greg Isenberg uses a clear example in his video about the marketing engineer role: a software company selling to commercial HVAC contractors, the firms that install and service heating and air conditioning. The obvious campaign is about running an HVAC business better. The specific one comes from a moment he describes in the buyer’s business: the technician “finishes a service call, spots a replacement opportunity, and the follow-up quote just never gets sent.” His verdict on the two: “Stop losing replacement revenue after every service call is obviously a much sharper angle than run your HVAC business better.”
The difference between the two angles can be written down, which is what makes it something a team can look for on purpose.
| A broad angle | A specific angle |
|---|---|
| Describes the whole business | Describes one moment in the buyer’s business |
| Uses your category’s words | Uses the words the buyer used when they told you about it |
| Promises a general improvement | Names what that moment costs, in money, time or customers |
| Fits every company in your market | Fits the buyers who live through that moment |
Which records does your company already have?
Three kinds of records hold most of what you need. Each one catches the customer at a different point, and that is why reading all three gives you more than reading one of them three times as long.
| Source | When it catches the customer | What it tells you | Where it usually lives |
|---|---|---|---|
| Sales calls | Before they buy | Why they started looking, and the words they use before they know yours | Call recordings, call notes in the CRM |
| Support tickets | While they use the product | Which part of their real work the product touches, and where it gets stuck | Your help desk or the support inbox |
| Cancellation notes | When they leave | What they bought it for and did not get, and what they went to instead | The cancellation form, billing notes, exit emails |
Cancellation notes are sometimes called churn notes. They are short, often a single line, and worth reading first, because a customer who writes one has no reason left to be polite about the problem.
How do you read them?
The question to read them for is which pain gets a buyer to take a demo. The method has seven steps. After the first round it becomes a habit you repeat each quarter, or whenever a new campaign starts.
- Pick one campaign and one buyer. Write down the broad angle you have now, in one line. You will compare against it at the end.
- Take a fixed sample from each source. For example, the notes from the last twenty sales calls, the last fifty support tickets and every cancellation note from the last quarter. A fixed sample stops you from reading only the records that agree with what you already think.
- Copy exact sentences, never summaries. Paste the customer’s words into one document with the source next to each line. Leave out names and anything else that identifies a person, because the sentence is what you need. Isenberg names what goes wrong here: a vague summary such as “customers want better collaboration”, which is the broad angle again. He is describing a summary written by an AI tool, and a summary written by a person falls into the same trap.
- Mark the moment each sentence describes. Before buying, during the work, or at the point of leaving, and then the concrete situation: a quote not sent, an invoice chased twice, a report rebuilt by hand.
- Mark what the moment costs. Lost revenue, hours, a customer gone, a mistake that reached a client. A moment without a cost makes a weak angle.
- Count, and look at who said it. Group the sentences by moment and count each group. Then mark which sentences come from deals you won, which your CRM records for each call, and check which moments come up with those buyers and with the buyers you most want. Isenberg’s example of a good weekly note shows why: “five sales calls this week mentioned emergency dispatch, but the calls that actually converted all talked about missed follow-up quotes after the tech left.” The most frequent moment and the moment that wins deals are not always the same one.
- Write the angle in one sentence, in their words. Who it is for, the moment, and what it costs. Then put it next to the broad line from step one.
How do you know the angle is specific enough?
Hold the new sentence against these five questions. If it fails one, go back to the document from step three rather than rewording it at your desk.
- Can you point to at least three sentences in your sample that say the same thing in the customer’s words?
- Would a buyer outside this moment read past it, while a buyer inside it would recognise themselves?
- Does it name a cost the buyer already feels, without you having to explain why it matters?
- Could a competitor run the same line unchanged? If so, it is still too broad.
- Does your product fix this moment? A campaign that promises a fix the product does not deliver comes back as support tickets.
What to do with the sentences afterwards
The document you built is worth more than the one campaign. Keep it, add the next sample to it each quarter, and note when a moment gets louder or quieter. Isenberg calls his version of this file “what the market is telling us” and says its “whole job is to show what’s changed”, for example when “the buyers are using a different phrase” than they did a month ago.
The same sentences serve more than the campaign brief:
- Landing pages and ads take their headline from the angle and their supporting lines from the other sentences in the same group.
- Sales gets the moments that win deals in the customers’ words, which is useful in the next call.
- Your AI tools write better drafts when they read how your buyers describe their problem before they start. Why that matters is covered in what a marketing engineer is, and what changes when you have one.
Who in your team should do this?
Someone on the marketing team who knows your buyers well. The reading needs judgement about your buyers far more than it needs technical skill. It also needs access: the call notes live in the sales tools, the tickets in the help desk and the cancellation notes in billing. Asking those teams for read access to a sample is the first real step.
Where a marketing engineer comes in
Everything above can be done by hand, with a shared document and no help from anyone. A marketing engineer is the person who connects a marketing plan to the systems it runs on. Once the reading becomes a habit, that technical half starts to matter: pulling the three sources into one place automatically, keeping the running file up to date, and connecting it to the AI tools your team drafts with, so every draft starts from your customers’ words. That half is what our fractional marketing engineer service does. The reading and the angle stay with your team, where the market knowledge already is.
