There’s something most email training skips completely and it's not deliverability, not design and not even strategy.
It’s this: why people actually open, read, feel things, and act on email.
Not the surface stuff, not subject line formulas or button colours. The REAL stuff — how the human brain works, what it responds to, what it filters out, and why most email copy misses before it’s even been read.
This is what the Email Copy & Psychology Guide is built around. And this blog pulls out the core thinking — but if you want the full frameworks, the exercises, the worked examples, and the pre-send checklist, you need the guide. It’s free. Go and get it!
Right — let’s get into it.
I’ve said this many times, and I’ll keep saying it:
The inbox is not a browsing environment (I mean I SCREAM this all the time). It is not social media or the place people go to discover things.
It’s a task environment (end of).
People go there to check, confirm, act, and move on. They are not in an open, exploratory mindset when they land in their inbox. They are filtering, they are clearing, they are deciding — very quickly — what stays and what goes or what resonates with them and if they should act in or outside of the inbox.
Your subscriber is not waiting for your email:
They’re in the middle of something, on their phone, half-present. Giving your email a fraction of a second before they decide whether it’s worth their time.
Which means your copy has a much harder job than most people realise.
It doesn’t just have to be good. It has to earn attention in an environment that is actively hostile to distraction.
Humans are not selfish in a calculated, villainous way. We’re selfish by design.
The brain is an energy-conservation machine. It filters everything through one lens: what does this mean for me? It’s an evolutionary mechanism — prioritising personally relevant information is what kept us alive for thousands of years.
Your subscriber is reading your email, thinking about themselves.
Their problems. Their goals. Their risk. Their time. Their life.
NOT your product launch. NOT your company news. NOT your award.
Every single word you write needs to pass through that filter or it gets discarded. Without guilt. Without a second thought. Just — gone.
This is why the most important question in email copy is one most teams never actually ask before they write:
WIIFM. What’s In It For Me?
Not for your business, not your product, not your quarterly target.
What does this mean for the human reading it, right now, in their specific situation?
If you can’t answer that in one sentence before you start writing, you’re not ready to write.
The guide has a full WIIFM rewrite activity where you take a real email, find every sentence that starts with ‘we’, ‘our’, or your brand name, and rewrite each one so it actually answers this question. It’s one of those exercises that feels obvious — until you do it and realise how much of your email was written for you, not them.
This is one of the biggest silent killers of email performance, and almost nobody names it.
When you sit down to write an email, you know your product inside out. You know what excites you about it. You’ve worked on it. You’re proud of it. So naturally, completely naturally, you write from that place.
You write announcements, you explain features, you celebrate milestones.
And your reader thinks: so what?
Not because they’re rude, because you haven’t told them why they should care.
The more you know about your product, the harder it is to write about it well. Knowledge creates assumptions. And assumptions are the enemy of clear, useful, reader-first copy.
Here’s what that looks like in practice:
|
What most people write |
What readers need to hear |
|
We’ve launched a new dashboard. |
You’ll never dig through five tools again. |
|
We’ve been in business for 10 years. |
You’re working with people who’ve seen everything. |
|
Our platform has 200+ integrations. |
It connects with the tools you already use. |
|
New feature: automated workflows. |
Your emails go out while you’re in bed. |
|
Contains peptides. |
Your skin repairs itself while you sleep. |
|
It’s recyclable packaging. |
You get a product you feel good about buying — and throwing away. |
Same information, but completely different experience for the reader.
That shift from feature or service to outcome, from business perspective to reader perspective — is what most email copy is missing.
Here’s another pattern I see constantly in email audits:
Assumptive copy.
This is when your email makes leaps about the reader that haven’t been earned.
It assumes they have the problem you’re solving. It assumes they’re further down the buyer journey than they are. It assumes they understand your world the way you do. It assumes your urgency is their urgency.
When copy makes these leaps, readers feel it — even if they can’t articulate why. It feels off. Like someone who doesn’t quite know them is trying to sell them something. And that feeling creates distance, not connection.
It also creates a deliverability problem over time.
When emails consistently don’t resonate — when they’re deleted, skimmed, quietly ignored — mailbox providers notice. The signal is the same as any form of irrelevance: this sender is not worth attention.
The antidote is straightforward but takes discipline:
Stop writing from what you know about your product.
Start writing from what you know about your reader — specifically what they know, what they feel, and where they actually are right now.
Not where you want them to be.
Great email copy doesn’t just communicate, it connects & provides an experience (feelings are everything, how does this make me feel subconsiously or consciously)
And that connection happens in a part of the brain that predates rational thought.
People make decisions emotionally first. Logic comes second — usually to justify a decision that’s already been made. Which means if your copy doesn’t connect at an emotional level, the logical argument doesn’t get heard. At all.
What are humans hardwired to respond to?
Fear of loss — more powerful than the desire for equivalent gain
The need for status, recognition, and belonging
Curiosity — the brain is compelled to close open loops
Social proof — we look to others to know what’s safe
The desire for certainty and safety
The pursuit of more: more money, more time, more confidence
These are human truths and not just B2C principles.
And yes — this absolutely applies in B2B too. B2B buyers are still humans. Behind every business decision is a person who wants to look smart in front of their team, protect their budget, avoid a costly mistake, and advance their career. Nobody ever bought a platform because of a feature list. They bought it because of how the decision made them feel.
As Gary Halbert once said: words have weight. The moment you outsource your message to an image, you lose the thing that actually moves people.
This is the part of the Email Copy & Psychology Guide I’m most excited about — because it’s something I’ve never seen covered properly anywhere else.
Here’s the overview:
When someone opens your email, their brain asks one question instantly:
“Did I get what I thought I was going to get?”
That’s the bridge.
The connection between what you promised in the inbox preview — the from name, subject line, preheader — and what you actually deliver inside the email.
When the bridge holds, readers stay.
When it breaks, they bounce.
And their brain quietly files you as ignorable.
Most copy breaks the bridge in three ways:
The subject line promises something specific — the email opens with a generic header that doesn’t answer it
The preheader teases a real insight — the email starts with a company announcement
The hook lands well — then the message pivots to something the reader didn’t ask for
Your first sentence should resolve the pre-open promise; do not repeat it.
They already saw the subject line, what they opened for is the payoff, give it in the first two lines or the most visually drawing component.
Hooks are what stop the scroll.
They’re the moment your copy creates a pull the brain feels compelled to follow. And they exist at every level of your email — subject line, opening sentence, section headers, CTAs.
There are four that work consistently:
Opens a loop the brain feels compelled to close. “The one thing most email audits miss.” The reader can’t not want to know what it is. Rule: always close the loop with substance, not clickbait.
Challenges a belief the reader holds. “Your open rate is not a success metric.” Provocation creates engagement — especially when it’s true and you can back it up.
Mirrors the reader’s reality back at them with precision. “You’re the person who owns email but has no actual time to fix it properly.” When someone reads a sentence and thinks that’s me — you have them.
“Most teams” is weak. “73% of B2B marketers” is a hook. Specificity implies evidence. Evidence builds trust.
The guide goes deep on all four — what each one does psychologically, how to use them across every part of your email, and how to avoid the versions that backfire.
These are thinking tools, not templates.
Each one maps to a different stage of how humans actually move through a decision. Which one you use depends entirely on where your reader is right now.
The guide has full B2B and B2C worked examples for every single framework — so you can see what each one actually looks like in practice, not just in theory. Get it here.
One more thing — because it comes up in almost every audit I do.
Design gets you noticed. Copy gets you remembered.
Design reduces cognitive load. Copy activates emotion. You need both. But you cannot replace one with the other.
An email stuffed with beautiful images and empty headlines is decoration. Not communication.
Test this now: take your last email and remove all the images. Does it still make sense? Is the message still clear? Could someone still act on it?
If the answer is no — your copy needs work. Not more design.
Everything in this blog is a taster.
The Email Copy & Psychology Guide goes much further — with the full five psychology principles, the complete cognitive biases section, the emotional triggers table, worked B2B and B2C examples for every framework, the WIIFM rewrite activity, and the full pre-send checklist that covers everything from your from name to your CTA.
Free. Practical. And it will change how you approach every email you write from here.
