200 Catchy Email Subject Lines (And How to Make Them!)

Your email subject line is the most important part of your email. In fact, Hubspot¹ reports that 35% of email recipients open an email based on the subject line alone.

This article will help you learn what goes into creating an email subject line that people want to click. Plus, you’ll get 200 actual email subject line examples you can use.

Let’s dive in.

What is An Email Subject Line? (Definition)

An email subject line or headline is the first line of text someone reads when they receive your email. This is the line of text you’ll usually type to grab the attention of your email recipient.

Email subject lines are crucial—they are the first impression. You might write the best email in the world, but if your subject line stinks, then nobody will read it.

A fair bit of psychology goes into writing a captivating email subject line. Let’s go into the key do’s and don’t’s.

Email Subject Line Do’s and Don’t’s

Do make sure to follow these best practices!

• Do Be Clear and Concise: Make the subject line clear, brief, and relevant.
• Do Use an Emoji: Emojis create a personalized flair. But if you use too many, it’ll be in the spam folder.
• Do Personalize: Write the recipient’s first name to boost the open rate².
• Do Use Emotion-Driven Words. Evocative words will create feelings. Feelings will make clicks.
• Do Leverage Curiosity: Hint at something intriguing without giving it away. Curiosity is a powerful force.
• Do Test and Optimize: Try A/B testing for different subject lines to determine which tactic resonates best with your audience.
• Send at the Right Time: 11:00 am EST has the highest open rate³ for email sends (and Tuesday is the best day to send).
• Do Emphasize Timing. Subject lines that include dates or a sense of urgency tend to perform better. In a study by Return Path⁴, 9 million subject lines were sent out and analyzed. It turns out that certain urgent phrases and words work better than others:

Top keywords in urgent subject lines	Average read rate for subject lines containing this keyword
Still time	33.73%
Limited time	14.93%
Expiring	16.60%
Last chance	16.71%
Now	15.75%
Expire	16.69%
Hurry	19.01%
Extended	9.20%
Running out	9.92%

But don’t abuse their fear of missing out, or you’ll come off as spammy and stressful.

Also, be careful of these “don’t’s:”

• Don’t Write Misleading Content: If you make a clickbait subject that doesn’t match the email content, your trust will go down the toilet.
• Don’t Use Spammy Language: Avoid overused sales language and excessive punctuation or all caps, which can trigger spam filters. You probably wouldn’t open an email with the subject: ”🔥🎉🚀 HURRY!!! Your EXCLUSIVE Deal Awaits! 🌟💰💸 Open NOW for FREE MONEY! 🎁🎁🎁”
• Don’t Write Overly Long Subject Lines: Long subject lines often get cut off, especially on mobile devices.
• Don’t Ask For Things: Mailchimp⁵ analyzed thousands of words related to donations and found that words such as “helping,” “fundraising,” “charity,” and “donate” all lead to negative effects on open rates. Instead, you might want to save the asking (if any) for later.
• Don’t Include Typos: A typo in the subject line screams unprofessional and unprepared.

Now, let’s get into some sample subject lines that you can use for your emails!

The 3 Psychological Triggers That Make a Subject Line “Clickable”

You’ve got the what (the 200 examples), but let’s talk about the why.

Why does a subject line like “You’re Invited!” work better than “Our Company’s Monthly Newsletter”? It’s not magic; it’s predictable human psychology. If you understand these three triggers, you can write 1,000 more great subject lines.

1. The Curiosity Gap (a.k.a. “The Brain Itch”)

Have you ever read a headline that you just had to click? “This One Mistake Could Cost You…”

Your brain goes, “…what mistake?! DO I MAKE THAT MISTAKE?!”

That feeling is called the Curiosity Gap. Behavioral economist George Loewenstein pioneered this. He found that curiosity is like an “itch” in the brain. It’s an uncomfortable gap between what we know and what we want to know.

A great subject line doesn’t tell the whole story. It teases the story. It opens a loop.

• Weak Subject: “How to Be More Productive” (Tells me everything. No gap.)
• Strong Subject: “This ‘secret’ could triple your productivity” (What secret? I need to know!)

Your reader’s brain will click the email just to scratch that mental itch.

2. Loss Aversion (a.k.a. FOMO)

Here’s a fun fact from psychologists Daniel Kahneman and Amos Tversky: for most of us, the pain of losing $20 feels twice as powerful as the pleasure of gaining $20.

We are psychologically wired to avoid loss. This is the engine behind FOMO (Fear of Missing Out).

This is why subject lines with urgency and scarcity work so well.

• “Ends Tonight”
• “Your Last Chance”
• “Limited time”

These phrases trigger that “loss aversion” panic. We’re not opening the email to gain a discount; we’re opening it to avoid losing it.

3. The Cocktail Party Effect

Picture this: you’re at a loud, crowded party. You’re tuning out all the noise… until, from across the room, someone says your name.

Ping! Your brain instantly locks onto it.

This is a real psychological phenomenon called the Cocktail Party Effect. Our brains are hardwired to filter out noise, but our own name is the “magic word” that breaks through the filter.

This is why personalization is so powerful. Using your recipient’s name in the subject line (e.g., “Vanessa, check this out”) isn’t just friendly; it’s a neuroscientific trick to grab their attention.

Catchy Email Subject Lines

Here are some really good subject lines that work for almost all occasions–just make sure they are true! Don’t use that subject line if you do not have an important announcement.

1. “I have an important announcement.” Mailchimp⁶ found that “announcement” (and similar words) caused a higher open rate. People want to be in the know!
2. “Question for you” This email subject line invites the receiver to open your email and help you. It also works because of the Benjamin Franklin Effect—when someone does a favor for you, they end up liking you more!
3. “Hey there, [name], check this out.”
4. “Your Sneak Peek Inside the Future of [whatever your industry is]”
5. ”🌟 Exclusive Offer Just for You – Ends Tonight!”
6. “Can You Believe This Happened?”
7. “Unlock the Secrets to Effortless Productivity”
8. “You’ve Never Seen Deals Like These 🚀”
9. ”🎉 Surprise Inside: A Gift Just for You!”
10. “This One Mistake Could Cost You (And How to Avoid It)”
11. “Flash Sale Alert: 50% Off Your Favorites!”
12. “This Week’s Top 10 Must-Reads for You”

Best Email Subject Lines for Sales

Sales are tricky because you want to balance relatability and selling perfectly. You also don’t want to mislead, which is EXTREMELY easy in sales emails.

GovX uses an email subject line that hints toward a “free” knife… but it’s just a discount. Bummer!

Many people who report emails as spam send those reports based on the subject line alone. Here are great examples to nail your sales subject line for your email campaign:

13. “You Have Two Choices.” Everyone loves to play games, and everyone likes to have options. This is a great subject line for sales, as choices influence people to take action.
14. ”Why You Can’t [insert problem here]” Why you can’t lose weight. Why you can’t sleep at night? Why you can’t feel happy at work? Find a common problem and offer reasons (hopefully your solution!).
15. ”Psst… Here’s a freebie.” People love the word “free,” but did you know the word “freebie” works even better⁷? Add this to your email, but please make sure to make the freebie worth it (or risk getting unsubs!).
16. ”So. Many. Deals… Find Something AMAZING Now 💸”
17. “You’re a Perfect Fit For [insert opportunity here].”
18. “Save up to $10/month for life”
19. “Hey, you forgot this—here’s your 20% off!”
20. “Get a [adjective] $20 off your next order.”
21. “Ready for a Game-Changer?"
22. "Limited Time Offer: 30% Off Your Next Purchase!"
23. "Solve [Problem] with This One Simple Tool"
24. "Last Chance: Don’t Miss Out on This Deal!"

Newsletter Subject Lines

Are you sending out a weekly/biweekly newsletter to your subscribers? Here are some great email subject lines to share in a blog post or an email marketing campaign.

31. “Fake Friends” Vanessa Van Edwards, the founder of Science of People, used this subject line in one of their newsletters, and it was a HIT! It’s short and gets the reader wondering, What are you talking about? Try combining a short subject line with an interesting/lesser-known topic.
32. ”One simple way to make yourself happier.” Ramit Sethi uses this fabulous newsletter subject line, which works because it provides value! Find a problem and offer a solution.

33. “3 crazy theories that [interesting thing here].” Mark Manson grabs the reader’s attention in this email’s subject line by being super intriguing. Who doesn’t want to read up on something almost too crazy to believe?

And since the average professional receives⁸ about 121 emails daily, yours must stand out to get noticed. Here are some winning options for cold emails.

90. Hope you’re doing well, [insert name here].” Writing like you’d be speaking to a friend is a personalized and informal way to grab attention. This subject line is great and looks like a text from a friend you haven’t spoken to.
91. ”I loved your article on [topic here].” I love it when people send me comments on my articles. And when I can tell they’ve read them and appreciate my tips? That gets them ahead of the game. A little appreciation goes a long way to getting attention!

Email Subject Lines for Jobs

Are you going on a job hunt? Once you’ve prepared your resume, decked out your LinkedIn, and perfected your elevator pitch, it’s time to move on to the email.

Sending out emails to companies you’re looking to get hired at can be daunting, but it doesn’t have to be! Here are my favorite lines that work more often than not:

159. “CV for [job position] — available immediately.” Try being direct and putting as much info as possible upfront. This one shows you’re ready and organized.
160. ”[Job Position] — [Name]” This is a variation of the above. Use this one if you don’t have a specific time you’ll be available or a CV ready yet.
161. ”Looking to help.”
162. “Following up on…”
163. “Referred by [friend] — [name]”

174. ”Happy Birthday [name here]—Here’s a Gift!” Combine a birthday and a gift, and you’ve got a one-two combo for an excellent email. Don’t forget to include a decent gift, though, or the receiver might feel like they’ve wasted their time.

177. “[Holiday] Guide: Everything You Need to Know”

Don’t Forget Your Subject Line’s “Best Friend”

Okay, real talk. Your subject line is only half the battle.

In every inbox, from Gmail to Apple Mail, there are two things your reader sees:

1. The Subject Line (The Headline)
2. The Preview Text (The Subtitle)

The preview text (or “preheader”) is that little snippet of text right after the subject. It’s your subject line’s “best friend.” And most people totally waste it.

Have you ever seen this?

Subject: “You Won’t Believe This…” Preview: “Having trouble viewing this email? Click here…”

Boooo! All that curiosity you built up is instantly killed. The “click here” text tells my brain this is a boring marketing blast.

A great preview text doubles down on the subject line’s promise.

Subject: “You Won’t Believe This…” Preview: “It’s the one mistake everyone is making.”

See? The subject opens the loop, and the preview text widens it.

Action Step: Check your email service (like Mailchimp, ConvertKit, etc.). Most have a specific field to write your preview text. If you don’t use it, the email client will just pull in the first line of your email. Always write custom preview text.

How to Avoid the “Spam Monster” (A Quick Guide)

You know what’s worse than a subject line that doesn’t get opened? A subject line that gets your email sent straight to the spam folder.

Spam filters are like over-eager bouncers at a club. They’re looking for any excuse to throw you out. And they’re triggered by specific “danger words” and-patterns.

It’s not just the obvious stuff, either. Common, “innocent” marketing words can get you in trouble.

Here are some of the most common triggers to use very carefully:

• Money Words: “Free,” “Cash,” “Bonus,” “Credit,” “Earn $,” “No cost,” “Price”
• Urgency Words (when overused): “Act now,” “Click here,” “Urgent,” “Instant”
• Salesy Words: “Best price,” “Discount,” “Sale,” “Affordable”
• Spammy Formatting:
  • USING ALL CAPS
  • Excessive punctuation!!!!!!!
  • Using symbols like $$$ or ***

Does this mean you can never use the word “free” or “sale”? No!

It’s all about context. The spam filters are looking for patterns.

• Likely Spam: $$$ FREE! ACT NOW! Win a prize!!! (This is desperate and hitting all the triggers.)
• Totally Fine: [Name], your free guide to public speaking is here (This is personal and contextual.)

Action Step: Read your subject line. Does it sound like something you’d yell at a stranger in the street? If so, rewrite it to sound like something you’d say to a friend.
