Most email advice focuses on automation, segmentation, and tools. Those matter. But none of it means anything if your emails don’t get opened and your links don’t get clicked.
I’ve written thousands of emails across my own lists and for clients over the past 16 years. I’ve seen what a 2% click rate looks like and what a 12% click rate looks like. The difference isn’t luck or magic. It’s craft. And craft can be learned.
The email that earns you $3,000 and the email that earns you $0 often differ by about 45 minutes of extra effort. A better subject line. A tighter hook. A clearer call to action. That’s it.
Subject Line Formulas That Work
Your subject line has one job: get the email opened. It doesn’t need to summarize your email. It doesn’t need to be clever. It needs to create enough pull that someone taps on it instead of scrolling past.
After years of testing, I’ve narrowed it down to four approaches that consistently perform.
Curiosity. Humans can’t resist an open loop. When you hint at something without revealing it, people need to know. “The one thing I’d change about my blog” works because readers want to know what that thing is. “I almost quit last Tuesday” works because there’s a story they need to hear. The key is being specific enough to be interesting without giving away the answer. “Something interesting happened” is too vague. “I lost 400 subscribers in one day (on purpose)” is specific and intriguing.
Benefit. Tell people exactly what they’ll get. “How I got 200 subscribers from one guest post.” “The $12 tool that replaced my $200/month stack.” These work because they promise a concrete outcome. The more specific the benefit, the better. “Grow your email list” is generic. “How I added 47 subscribers yesterday without spending a dollar” makes people lean in.
Urgency. Real urgency, not manufactured scarcity. “Price goes up Friday” works when the price actually goes up Friday. “Last day to join the workshop” works when it’s the last day. What doesn’t work is fake urgency on every email. Your audience learns fast. If everything is “urgent,” nothing is. Save urgency for when it’s real, and it’ll hit harder.
Personalization. And I don’t mean mail merge tags. I mean writing subject lines that feel like they came from a friend, not a brand. “Quick question for you.” “Saw this and thought of you.” “Can I be honest about something?” These feel personal because they mirror how real people text each other. I use these sparingly, maybe once a month, but they consistently get my highest open rates.
One pattern I’ve noticed: my worst-performing subject lines are always the ones that try to be too clever. Puns, wordplay, vague teasers. They might make you feel creative, but they don’t get opened. Clarity beats cleverness in the inbox, every time.
Preview Text: The Forgotten Conversion Tool
Preview text is the gray text that appears next to (or below) your subject line in most email clients. On mobile, it’s often the first thing people read after the subject line. And most bloggers either ignore it completely or let it default to “View this email in your browser.”
That’s like paying for a billboard and leaving half of it blank.
Your preview text should complement your subject line, not repeat it. If your subject line creates curiosity, the preview text should deepen it. If your subject line states a benefit, the preview text should add context.
Subject line: “I lost 400 subscribers in one day (on purpose)”
Bad preview: “Read on to learn more about email list management.”
Good preview: “And my revenue went up. Here’s why I’d do it again.”
Subject line: “The $12 tool that replaced my $200/month stack”
Bad preview: “View this email in your browser”
Good preview: “I feel dumb for not finding this sooner.”
Most email platforms have a dedicated preview text field. Use it on every single email. I’ve seen preview text alone increase open rates by 5-8% when done well. That’s a lot of extra eyeballs for 30 seconds of work.
Email Copy Structure: Hook, Body, CTA
Once someone opens your email, you’ve got about three seconds before they decide to keep reading or close it. Your first line matters more than any other.
The Hook (First 2-3 Lines)
Your opening line should do one of three things: make a bold statement, ask a provocative question, or drop the reader into the middle of a story.
Bold statement: “I stopped publishing blog posts for 30 days. My traffic went up.”
Provocative question: “What if everything you’ve read about SEO in the last two years was wrong?”
Story drop: “Last Thursday at 2am, I got an email from a reader that changed how I think about my entire business.”
What doesn’t work: “Hey! Hope you’re having a great week!” Nobody opens an email to read a greeting. Get to the point. Your subscribers are busy. Respect their time by making the first line count.
The Body
Keep paragraphs short. One to three sentences max. Walls of text don’t get read in emails. They get deleted.
Stick to one idea per email. I know it’s tempting to pack in three tips, two links, and an announcement. Don’t. The emails that perform best are the ones that go deep on a single topic. Think about it this way: your email should be about one thing, explored well enough that the reader walks away with something useful.
Write like you’re texting a smart friend. Not dumbing it down. Not being formal. Just… talking. Read your email out loud before you send it. If it sounds like you’re reading a corporate memo, rewrite it.
Use formatting strategically. Bold a key phrase. Break a long section with a one-line paragraph. Use bullet points sparingly, and only when listing more than two items. But don’t format everything. If every line is bold, nothing is bold.
The CTA (Call to Action)
Every email needs exactly one thing you want the reader to do. Click a link. Reply. Buy something. Register. One action.
Place your primary CTA after you’ve built enough interest that clicking feels like the natural next step. Don’t put a link in the first paragraph. Build context first. By the time readers reach your CTA, they should be thinking “yes, I want that” before they even see the link.
Make the CTA a text link, not a button. I’ve tested this dozens of times. In plain-text-style emails (which most bloggers should be sending), a hyperlinked phrase outperforms a flashy button. “Grab the template here” as a link works better than a big orange “DOWNLOAD NOW” button. Buttons scream marketing email. Text links feel personal.
The Single-CTA Principle
I’m going to hit this harder because it’s where most bloggers mess up.
One email. One ask. That’s the rule.
When you give readers two links, click rates drop on both. When you give them three, it drops further. I’ve seen this pattern across hundreds of email campaigns. Choice creates paralysis.
“But what if I want to link to my new post AND mention my course?” Pick one. Send two emails on different days. Or mention the course in the P.S. line (more on that below) but keep your primary CTA focused on one action.
The exception: newsletters that are explicitly a roundup format. If your audience signed up for “five links every Friday,” multiple links are the format, and that’s fine. But even then, make one link the featured item and build the email around it.
For every other email type, sales emails, nurture emails, launch emails, content emails, one CTA. I’ve watched clients double their click rates by going from three CTAs to one. Not a small improvement. Double.
Storytelling in Email: The Most Underused Conversion Tool
Facts inform. Stories sell. This isn’t a marketing platitude. It’s something I’ve proven with real revenue numbers over years of testing.
The emails that generate the most clicks and the most sales in every list I manage are stories. Not tips. Not tutorials. Stories that make a point.
Here’s why stories work in email: they bypass the “I’m being marketed to” filter in your reader’s brain. When you open with “Three tips for better headlines,” the reader’s guard goes up. They know they’re being taught, and they’re skeptical. When you open with “Last month, a student in my course sent me a screenshot of her revenue dashboard,” the reader leans forward. They want to know what happened.
The structure is simple:
Setup: What was the situation? Paint a quick picture. Two to three sentences.
Conflict: What went wrong, or what was the challenge? This is where tension lives.
Resolution: What happened? What did you (or the character) do?
Lesson: What’s the takeaway? This is where your email’s actual point lives.
Bridge to CTA: How does this lesson connect to whatever you’re asking the reader to do?
You don’t need to be a great writer to tell good stories. You just need to pay attention to your own experiences. Every client problem you solve, every mistake you make, every small win, that’s email content. I keep a running note on my phone called “email stories.” Whenever something interesting happens, I jot down two sentences. When it’s time to write, I pick from the list. I’ve got over 200 entries in there.
The stories don’t have to be dramatic. “I spent 45 minutes trying to fix a CSS issue that turned out to be a caching problem” is a relatable story for any web developer on your list. It’s real. It’s specific. And you can bridge it to almost any lesson about patience, debugging, or the value of clearing your cache first.
P.S. Lines That Drive Clicks
The P.S. is the most-read part of many emails. It sounds counterintuitive, but eye-tracking studies have confirmed it for decades. People skim to the bottom, read the P.S., and then decide whether to read the full email.
Use this to your advantage.
P.S. as secondary CTA. If your email is about a blog post but you also want to mention your course, put the course in the P.S. “P.S. If you want to go deeper on email marketing, my course covers everything in this email and 12 more lessons. Details here.” You keep your main email focused while giving motivated readers a second path.
P.S. as urgency reminder. During a launch, the P.S. is where deadlines go. “P.S. The early-bird price ends Thursday at midnight. After that, it’s $199 instead of $149.” Short. Specific. No pressure in the body, but the deadline is right there at the end.
P.S. as social proof. “P.S. 340 bloggers enrolled in the last round. Here’s what Priya said about it: [short testimonial].” This works because it feels casual, like an afterthought, even though it’s strategic.
P.S. as personality. “P.S. I wrote this entire email while waiting for my build to compile. If there are typos, blame webpack.” This has nothing to do with selling, but it makes you human. And humans open emails from other humans.
I include a P.S. in about 80% of my emails. It’s become such a natural part of my writing that readers have told me they scroll to the P.S. first. That’s the habit you want to build.
Putting It All Together
Here’s what a high-performing email looks like when you combine everything in this chapter:
Subject line: Curiosity or benefit-driven, 4-8 words.
Preview text: Complements the subject, doesn’t repeat it.
Opening line: Hook that earns the next sentence.
Body: One idea, short paragraphs, conversational tone.
Story: Real experience that connects to your point.
CTA: One clear action, text link, placed after value is established.
P.S.: Secondary CTA, deadline, social proof, or personality.
Writing emails this way takes more time than throwing together a quick update. But the difference in results is massive. I’ve seen bloggers go from $500/month to $3,000/month in email revenue without growing their list at all. They just got better at writing emails people wanted to open, read, and click.
That’s the compounding part. Every good email builds trust. Trust increases open rates. Higher open rates improve deliverability. Better deliverability means more people see your next email. And the cycle continues.
Chapter Checklist
- Write five subject lines using each formula (curiosity, benefit, urgency, personalization)
- Set up preview text for your next email (don’t leave it as default)
- Audit your last five emails: does each one have a single, clear CTA?
- Remove greetings like “Hope you’re well” from your email openings
- Identify three personal stories you could use in upcoming emails
- Start an “email stories” note on your phone
- Write a P.S. for your next three emails before you write the body
- Read your next email draft out loud before sending
Chapter Exercise
Take your worst-performing email from the last 90 days (lowest open rate or click rate). Rewrite it using what you’ve learned in this chapter.
- Write three new subject lines. Pick the one that creates the strongest pull.
- Write preview text that complements your new subject line.
- Rewrite the opening line as a hook: bold statement, question, or story drop.
- Cut the body down to one single idea. Remove anything that dilutes it.
- Reduce to one CTA. If you had multiple links, pick the most important one.
- Add a P.S. that either reinforces the CTA or adds a secondary action.
Compare the original and rewrite side by side. You’ll see the difference immediately. If you want to go further, send the rewrite to a small segment (10-20% of your list) and compare the results to the original. Let the data confirm what you already feel.
