There's a man in neuroscience literature known only as Elliot.
Elliot had a tumour removed from his brain, and the surgery damaged his ventromedial prefrontal cortex — the bit that connects emotion to reasoning. His IQ was untouched. His memory, his language, his ability to analyse a problem, all completely intact. On paper, he was fine.
But he couldn't make a decision...any decision at all. Asked whether he'd prefer an appointment on the Tuesday or the Thursday, he could reason through the pros and cons of each, endlessly, without ever arriving at an answer — because no option ever felt better than the other. His neurologist, Antonio Damasio, summed it up in five words that I think about more often than is probably healthy: to know but not to feel.
Elliot lost his job. He lost his marriage. Not because he'd stopped thinking, but because he'd stopped feeling — and it turns out that without the feeling, all that flawless reasoning goes precisely nowhere.
I bring this up because most email copy is written as though the reader is Elliot. Here are the features. Here are the specifications. Here is the logic. Please now assemble these facts into a purchase.
That's not how anybody works. It's not how your B2C subscribers work, and it's very much not how your B2B buyers work either, which is the bit that surprises people the most.
Whenever I say “emotion drives decisions” in a room full of marketers, somebody's face does a thing. A slight tightening. The look of a person who has spent three years justifying their budget in spreadsheets and does not want to hear that feelings are involved.
So let's do the numbers, because they're on our side.
Les Binet and Peter Field went through thirty years of IPA effectiveness data and found that emotional campaigns beat rational ones on every single brand metric measured: awareness, commitment, trust, differentiation, quality, fame and image.
Rational campaigns produced on average one brand effect; emotional campaigns produced 1.7. And on the business side it was the same story: emotional work outperformed rational on profit, sales, market share, penetration, loyalty and price sensitivity. Over the long term, emotional campaigns were almost twice as likely to deliver top-box profit growth.
Then there's the B2B research, which is the one I'd pin above your desk.
Read that again, because it undoes almost everything B2B email is built on. The business case is not the thing that moves the decision. The personal stakes are!!
The same research found that B2B brands generate higher emotional connection than B2C ones, where a typical consumer brand connects emotionally with somewhere between 10% and 40% of its customers, seven of the nine B2B brands studied were above 50%.
Which makes total sense when you think about who's actually reading your email. A consumer who buys the wrong moisturiser has wasted twenty quid. A Head of Marketing who signs off the wrong platform has staked their credibility, their budget, and possibly their job on it. The stakes are personal, the fear is personal, and the decision is emotional long before anybody builds the business case to justify it.
None of that is manipulation; all of it is relevance. The difference between the two is whether the feeling you're activating is true.
Decisions get made emotionally and justified logically.
Not the other way round, and not simultaneously.
Which means the sequence of your copy matters more than the content of it. If your email opens with your logical argument — the features, the specification, the integration list, the fact that you've been trading for six years, you're presenting evidence to a court that hasn't convened yet.
The reader hasn't felt anything, so there's nothing for the logic to attach to. They skim it, they file you as ignorable, and they move on. Litmus splits email engagement into three bands: a glance is under two seconds, a skim is two to seven, and a read is eight seconds or more. Average read time sits somewhere around twelve seconds
TWELVE SECONDS!! That is your entire window to make somebody feel something. If you've spent the first eight of them clearing your throat, you never had a chance.
This is why the sequencing frameworks work, and it's why they've survived decades of people declaring them dead. PAS makes you name a pain before you offer a fix. BAB makes you paint a current state before you sell a better one. The 4P's make you establish the problem before you promise anything. AIDA, the OG — makes you earn attention before you ask for action.
They're not formulas but instead a more forced emotional order. They stop you doing the thing every business instinctively wants to do, which is to lead with itself.
We talk about email copy as though it's driving one decision: buy, or don't. It isn't. It's driving five, in sequence, and each one is its own emotional gate.
Most emails fail at gate two or three and get blamed at gate five. Then somebody suggests testing a new button colour.
Four failures, and I see all four constantly:
Take the last sales email you sent, and run it through this:
Find every sentence beginning with we, our, or your brand name, and rewrite it starting with you. Not just swapping the pronoun — actually answering what changes for the person reading. If you can't answer it, the sentence goes.
Find your recognition moment. There should be one line where the reader thinks that's me. If there isn't, you've written information, not copy.
Check your proof is doing fear-reduction work, not showing off. Named, specific, peer-level. “Brands like yours” beats “our clients”.
Check any urgency is real. If it isn't, replace it with empathy and a positive outcome — one activates fear, the other activates hope, and over a sustained programme hope paired with proof wins.
Check the first screen resolves the subject line's promise instead of repeating it.
Ask the one-goal question: what is the single thing you want this reader to understand, feel, or do? If you can't say it in one sentence, you're not ready to write it.
Emotion is not a magic wand, and I'd be doing you a disservice if I pretended otherwise.
It amplifies whatever's underneath it, in both directions. If the offer is wrong, if the product doesn't do what you say, if you've invented a statistic to sound authoritative — emotional copy will get you found out faster, not slower. Made-up specificity is worse than vagueness, because it destroys trust the moment somebody checks.
And rational copy absolutely has a job. It's just a different one. It works at the point of action, for someone who has already decided emotionally and now needs the evidence to justify it — to themselves, to their boss, to procurement. It's worth noting too that the IPA data skews towards large, established consumer brands, and in highly technical or complex B2B markets, education-led rational content can outperform pure emotional brand work.
So don't take this as “delete the spec sheet”. Take it as: the spec sheet is the second thing, never the first.
Because the reader has to feel something before the facts have anywhere to land.
Elliot knew everything and could decide nothing. Your subscribers are the opposite — they'll feel it in under two seconds and construct the reasoning afterwards. Write for that, and the decision gets a lot easier to influence.
