How To Craft Email Subject Lines That Actually Get Opened (My Real Formula)

Here's the thing nobody on the email-marketing internet wants to tell you: if your subject lines aren't getting opened, the rest of your email doesn't matter. You can write the cleanest copy in the world. You can have the best offer of the year. None of it lands if the subject line isn't pulling people into the inbox.

I email my list every single day. I have since Funnel Hacking Live. I've had basically zero unsubscribes in that whole stretch. And I get a consistent 30-45% open rate on a list that includes a lot of cold subscribers from giveaways and lead magnets — not just my warmest fans.

The thing I learned the hard way is this: subject lines aren't a creative-writing exercise. They're a conversation starter.

If you treat them like ad copy, you lose. If you treat them like a text from a friend, you win. Let me show you exactly what I do.

The Three Tests Every Subject Line Has To Pass

Before I send any email, I run the subject line through three quick filters. If it fails any of them, I rewrite.

1. Does it sound like a human, or like a brand? "Big news inside!!!" is brand voice. "you're going to think this is dumb" is human voice. Inboxes are full of brand voice. Human voice is what cuts through.

2. Does it create curiosity without being clickbait? There's a difference between curiosity ("the dumb thing that tripled my email opens") and clickbait ("YOU WON'T BELIEVE WHAT HAPPENED NEXT"). The first one delivers on the promise. The second one teaches your subscribers to stop trusting you.

3. Could it have come from someone they actually know? Your subject line should look like it came from a friend who happened to email you, not a marketing department. Lowercase. Casual punctuation. Sometimes a typo. Sometimes no period. The minute it looks "designed," it dies.

My Actual Formulas

Here are the four templates I rotate through. They cover about 80% of what I send.

1. The Whisper

Short. Lowercase. Specific. No exclamation marks.

• quick thing about your fishbowl
• did you see what kelly did
• the email i almost didn't send

Whispers feel personal because they don't try to compete with the rest of the inbox. While everyone else is screaming, you're the one note that sounds like a human.

2. The Open Loop

You open a story. You don't close it.

• I almost lost a $4k client over this
• he told me my funnel was "cute"
• what happened in my inbox at 11pm last night

The brain hates an open loop. It needs to know how the story ends. Open the loop in the subject line, deliver in the email body. Don't ever cheat on the delivery — that's how you train your list to ignore you.

3. The Honest Confession

Vulnerability cuts through hype like nothing else.

• I think I've been doing this wrong
• the email mistake that cost me leads
• real talk: I almost quit last month

You'd be amazed how much trust you build with subscribers when you tell them the things most marketers won't.

4. The Direct Question

Asked plainly. No setup. No marketing-speak.

• are you actually using your email list?
• what's stopping you from sending more?
• how much would 50% open rates change your business?

Questions force engagement at the inbox level. Even if they don't open, the question stays in their head — which means they're more likely to open the next email.

The Mistake That Lands You In The Promotions Tab

I learned this from Perry Belcher and it changed how I write. The Gmail promotions tab is worse than the spam folder. People check their spam. Nobody checks promotions.

Here's what gets you flagged into promotions:

• Words like deal, discount, free, limited time, now
• Excessive punctuation (!!!, ??)
• Image-heavy emails with a tiny bit of text
• Symbols and emojis in subject lines (yes, even one)
• Any tracking pixel that smells "marketing"

If you write subject lines that sound like a friend texting you, none of those triggers get pulled. That's the whole game.

The Daily-Email Truth Nobody Talks About

Most people are scared to email more often because they think they'll lose subscribers. The opposite is true.

When I started emailing daily, here's what happened:

• Open rates went up, not down
• Unsubscribes were lower than when I emailed weekly
• Replies started coming in (which boosted deliverability)
• My list felt like a real audience instead of a list

The subscribers who don't want daily emails leave fast. Good. The ones who stay get warmed up by the constant cadence and become your actual buyers.

I run all of this through ClickFunnels' email workflow tools — same place my fishbowl funnels live, same place my tags get applied. Keeps the whole thing in one stack instead of duct-taping five tools together.

The Bottom Line

Stop writing subject lines like a brand. Start writing them like a friend.

Make them short. Make them specific. Make them sound like they came from a real person on a Tuesday afternoon, not a marketing automation tool at 6am sharp.

Test the four formulas above for two weeks. Keep what works. Throw out what doesn't.

You'll see the difference in the open-rate column inside seven days. I promise.
