The three mistakes that make readers delete your emails

Most emails aren't boring on purpose.

They're boring by default. They slip into patterns so common their writers stopped noticing them.

We've catalogued 2,084 emails from 180 brands. The same three patterns show up in the emails that don't get read, don't get clicked, and don't make money.

We call them boring types. And each one costs you something: opens, clicks, trust, revenue.

There's a scoring system behind this. But before the score matters, you need to understand what it's measuring: whether your email is worth reading.

And most email advice makes it worse.

"Be professional" creates Robots.
"Add value" creates Professors.
"Create urgency" creates Clingers.

The advice isn't wrong — it's just incomplete. It tells you what to aim for without telling you when you've gone too far.

So here are the types broken down:

You've received this email.

The Robot email sounds like it was written by the legal department — from subject line to sign-off. Passive voice. Announcement framing. Third-person references to the sender's own company.

Nobody's excited to open an update. Nobody clicked "subscribe" because they wanted confirmations.

The Robot mistake is defaulting to what sounds professional instead of what gets read. Every Robot email is answering a question your subscriber didn't ask.

I didn't ask for generic club updates. But I did ask for ways to get better at jiu jitsu.

The longest subject line in our database is 156 characters:

The Professor usually has good ideas. They're just buried under too much setup before the point.

By the time you get there, your reader's thumb already moved on.

The Professor mistake is confusing comprehensiveness with clarity. It shows up everywhere — subject lines that give away the whole movie in the trailer, body copy that over-explains before making a point, CTAs buried under three paragraphs of setup.

Your reader doesn't need to know everything. They need one reason to keep reading.

That 156-character subject line has three good ideas in it. Pick the most interesting one and let the rest live in the body.

The Clinger has a tell. It's the word "just."

These are from real emails in our database. And they all do the same thing: apologize before saying anything.

The Clinger email hedges its own value. "No pressure." "Whenever you're ready." "No worries if not." It reads like the sender doesn't believe their own email deserves to be opened.

One brand in our database closed a sales email with: "No pressure and you're always welcome to join down the road." That's directly giving your reader permission to ignore you.

The Clinger mistake is treating every send like an imposition. Your reader signed up. They asked to hear from you. Say something worth their time and stop softening it.

In the MODULR Method, each of these is a -1 penalty.

Each one represents an email that's harder to open, harder to trust, and harder to act on.

A lower score or multiple penalties is still sendable, but as the penalties creep up, your readers will slowly stop reading.

The score is a proxy for one question: does this email earn its spot in someone's inbox?

These three patterns are the most common reasons the answer is no.

Pull up the last email you sent. Read through it.

Am I announcing something nobody asked about? (Robot) Am I explaining when I should just be making a point? (Professor) Am I softening instead of saying something worth their time? (Clinger)
