Email Subject Lines That Actually Get Opened (And How to Write Them)

I’ll be blunt: most people write awful subject lines. They just do. I mean, you probably have 200 unopened emails in your inbox right now. Think about it. Why didn’t you open them? Because the subject line gave you zero reason to care.

The truth? Your subject line is like the doorman to a nightclub. If he doesn’t like your look, you’re not getting in. Doesn’t matter how good the music inside is, or how cheap the drinks are. No entry.

So if you want your emails read, if you want clicks and conversions, if you want people to actually look forward to what you send, you need to master this one skill. Writing subject lines that actually grab attention.

Why Subject Lines Carry All the Weight

Here’s the thing: I used to spend hours (literally, HOURS) obsessing over the content of my emails. I’d polish every sentence, drop in clever CTAs, and hit send with a smug little smile. And then, nothing. Crickets.

Why? Because only a handful of people opened them.

It’s humbling. Like cooking a five-course meal and nobody even showing up at the table.

Stats back it up too. Around 47% of people decide to open (or ignore) an email based purely on the subject line. Almost half. Which means, forget the body for a second, you’re already winning or losing the game before they even click.

Types of Subject Lines That Actually Work

Let’s cut through the fluff. I’ve tested dozens of subject line styles, and here’s the truth: only a few categories consistently pull weight. The rest, meh, they fade into the inbox abyss.

1. The Curiosity Hook

You ever see a half-told story on Twitter (or X, whatever we’re calling it today) and suddenly you have to know the ending? That’s the curiosity hook.

  • “This mistake cost me $500 last week”

  • “The email I almost didn’t send”

They leave a gap in your brain that demands to be filled.

2. The List Subject

Humans love numbers. Don’t ask me why. Maybe it’s because lists feel safe and organized.

  • “7 hacks that doubled my affiliate sales”

  • “5 blogging blunders that cost you readers”

It’s like your brain thinks, “I can handle 5 things. Sure, let’s open this.”

3. The Urgency Play

Deadlines make people twitchy. Scarcity, too. But listen, overdo this and you’ll look like a used car salesman.

  • “Offer ends tonight at midnight”

  • “Only 2 spots left for this training”

The trick is being believable.

4. The Benefit Promise

Honestly, sometimes direct works best. If you know your audience wants a clear win, just spell it out.

  • “How to grow your list by 100 subs this week”

  • “The email formula that gets replies every time”

No games. Just results.

5. The Personal Touch

This one still works. Seeing your name in an inbox makes people pause.

  • “Sarah, quick tip for your blog today”

  • “John, this could save you hours”

But if every subject line has their name in it, the magic fades.

6. The Question Format

Our brains love to answer questions, even silently.

  • “What’s really holding back your email growth?”

  • “Want 50% more opens with a simple tweak?”

If you word it right, people click just to confirm their own answer.

7. The Shocker

This one’s fun. Sometimes you just have to slap people out of autopilot.

  • “Stop building your list (until you see this)”

  • “90% of affiliate marketers quit for this reason”

But again, shock without substance = instant unsubscribe.

The Mistakes That Kill Your Subject Lines

I’ve made all of these. Maybe you have too.

  • Too vague: “Check this out.” Check what out?

  • Too long: If it doesn’t fit on a mobile screen, forget it.

  • Too spammy: “GET $$$ FAST!!!” You’ll end up in the junk folder.

  • Overhyped: If you scream “life-changing secret” and the email is just an ebook, you’ve lost trust forever.

A Simple Process for Writing Better Lines

Here’s my workflow. It’s not perfect, but it works.

  1. Write 10 subject lines for every email. Yes, 10. The first three will be boring. Around line 7 you’ll get creative.

  2. Say it out loud. If it sounds robotic, rewrite it. Imagine you’re texting a friend.

  3. Test everything. If your email platform lets you split test, do it. The results will surprise you.

  4. Build a swipe file. Every time a subject line grabs your attention in your own inbox, save it.

Real Examples That Crushed It

Here are a few that pulled crazy open rates for me:

  • “I didn’t think this would work (but it did)”

  • “Your free traffic source inside”

  • “The $27 mistake that nearly cost me big”

  • “Read this before posting your next blog”

I still use variations of these all the time.

All done

Here’s the bottom line. Your subject line is the ticket booth. No ticket, no entry. It doesn’t have to be genius, but it has to make people curious enough to peek inside.

Switch things up. Don’t always use lists. Don’t always use questions. Treat your subscribers like actual humans with moods and attention spans that change daily.

And please, for your sanity, remember this: a subject line isn’t about tricking someone into opening. It’s about giving them a reason to believe the inside is worth their time.

Is Your Traffic Actually Sabotaging You? Read This Before Sending Another Click

I used to think traffic was the problem. Or the lack of it, rather. “If I could just get more eyeballs on my link,” I’d whisper to myself like some sort of digital incantation while watching my email open rate crawl at 8.3%. That was a few years ago. I’ve since learned something odd, not all traffic is good traffic . In fact, some of it is trash. Worse, it’s a poison drip into your systems. 🚨 More Traffic ≠ More Sales People online talk about “driving traffic” like it’s some mystical rite of passage. But no one tells you what kind of traffic you’re driving, or where it’s heading. You wouldn’t pump diesel into a Ferrari, right? That’s what a lot of affiliates are doing. Bleeding money. Burning leads. Getting ghosted by their own lists. I did. I once paid for a traffic package that promised "real human visitors." Spoiler: they were real human disinterested strangers who bounced faster than a ping pong ball on pavement. I felt like I'd just paid for ghosts. Let’s unpack it...
