Use beehiiv if you want to test headlines like a growth nerd. Use Substack if you want headlines that feel personal, sharp, and very human. The best headline is not the cleverest one. It is the one that gets the right reader to open.

The simple difference

beehiiv feels like a newsletter lab. Substack feels like a writer’s room.

That difference matters a lot for headlines.

On beehiiv, you may write headlines with clicks, segments, referrals, and growth in mind. You think like this:

• Will this get opened?
• Will this drive a click?
• Can I test a better version?
• Can I spot the winner fast?

On Substack, you may write headlines with trust in mind. You think more like this:

• Does this sound like me?
• Will my readers care?
• Does it feel honest?
• Would I open this from a friend?

Both can work. But they reward different styles.

beehiiv headline examples

beehiiv is great for punchy, clear, benefit-heavy headlines. It suits newsletters that care about growth. Tech, finance, marketing, AI, e-commerce, startups, media, and creator tips fit well here.

Here are some beehiiv-style headline examples:

• “5 AI tools that saved me 7 hours this week”
• “The landing page mistake costing you sales”
• “How we grew from 0 to 12,000 subscribers”
• “This referral trick added 486 new readers”
• “3 charts that explain the creator economy”
• “The email template I use every Friday”
• “Why your welcome email is underperforming”

Notice the pattern.

The headlines are direct. They use numbers. They promise a useful result. They make the reader think, “Fine, I need to see that.”

beehiiv also works well with curiosity headlines. But be careful. Curiosity is spicy. Too much turns into clickbait soup.

Better:

• “The tiny pricing change that raised revenue by 18%”

Worse:

• “You won’t believe what happened next…”

The first one gives proof. The second one smells like 2014 internet sludge.

Substack headline examples

Substack headlines often feel more personal. They can be softer. Stranger. More essay-like. Readers on Substack often follow a person, not just a topic.

So the headline can sound like a thought you texted to a smart friend.

Here are some Substack-style headline examples:

• “I miss when the internet felt smaller”
• “What I learned from a year of saying no”
• “The weird peace of having fewer plans”
• “Why I stopped trying to be productive every hour”
• “A short note on envy”
• “The book that made me feel less alone”
• “I don’t think ambition means what it used to”

These are less “download my cheat sheet.” More “come sit with this thought.”

That is not weaker. It is just a different game.

Honestly, it feels like Substack rewards emotional clarity more than headline tricks. If your headline sounds fake, readers can smell it fast.

Which platform helps you write better headlines?

beehiiv helps you improve headlines with data. That is its big win.

You can track open rates, clicks, subscriber growth, and referral results. Depending on your plan and setup, you may also run tests and compare patterns over time. This helps you stop guessing.

For example, say you send these two headlines to a business newsletter list:

• A: “How to get more newsletter subscribers”
• B: “The 3 signup forms that got us 2,100 subscribers”

Headline B will often win. It is more specific. It has a number. It hints at proof. If B gets a 39% open rate and A gets 27%, your next headline becomes easier to write.

Substack helps you improve headlines with reader feel. Replies, comments, likes, and paid conversions matter. You learn what your people react to.

A Substack writer might test these two naturally over time:

• “Some thoughts on burnout”
• “I thought rest would fix me. It didn’t.”

The second one has more voltage. It has a point of view. It feels lived in.

The annoying parts

beehiiv gives you more knobs to turn. That is good. Also, mildly exhausting.

Expect to waste time on tiny decisions if you love data too much. A subject line test can turn into a 20-minute debate with yourself over one word. “Guide” or “playbook”? “Mistake” or “trap”? Suddenly lunch is gone.

Substack has the opposite issue. It is simple. Very simple. Sometimes too simple.

If you want deeper testing tools, tighter audience splits, or more growth features, you may hit a wall. It drives me crazy that strong writers sometimes have to guess which headline worked and why. Replies are nice. Clean data is nicer.

Headline formulas for beehiiv

Use these when you want action, clicks, and measurable growth.

• Number + result: “7 ways to improve your open rate this week”

Try this test. Read your headline once. Ask, “What does the reader get?” If the answer is fuzzy, rewrite it.

Headline formulas for Substack

Use these when you want connection, trust, and repeat reading.

• Confession: “I was wrong about discipline”

• Direct feeling: “I miss being bored”

Good Substack headlines sound like a real person had a real thought.

Do not sand off the edges. The edge is often the reason people open.

Side-by-side headline makeovers

Here is how the same idea might change by platform.

See the split?

beehiiv headlines sell the value fast. Substack headlines sell the feeling.

So, which should you choose?

Choose beehiiv if your newsletter is built for growth. Pick it if you care about testing, referrals, sponsors, audience segments, and sharper numbers.

Choose Substack if your newsletter is built around your voice. Pick it if you write essays, commentary, personal notes, paid posts, or community-driven pieces.

If you write for operators, marketers, founders, or niche professionals, beehiiv headline styles may fit better. If you write for readers who follow your taste and personality, Substack headline styles may feel more natural.

Quick rules for stronger headlines

• Be specific. “How I gained 1,000 readers” beats “Newsletter growth tips.”
• Use numbers when they add trust. Do not force them.
• Skip vague cleverness. Readers are busy and mildly annoyed.
• Show the payoff. Make the open feel worth it.
• Match the platform mood. beehiiv likes clear value. Substack likes clear voice.
• Write 10 options. The first one is usually plain oatmeal.

The best move is simple. Write the headline for the reader, not the platform. Then adjust the style. On beehiiv, sharpen the promise. On Substack, sharpen the truth.

Final pick: beehiiv wins for headline testing. Substack wins for headline intimacy. Your job is to know which win matters more.
