Your email subject line is the most important part of your email. In fact, Hubspot1https://blog.hubspot.com/sales/subject-line-stats-open-rates-slideshare 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 rate2https://mailchimp.com/resources/catchy-email-subject-lines/
  • 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 rate3https://blog.hubspot.com/sales/best-time-send-email-report-2015?=&_ga=2.141218610.1693432634.1531769354-1791073514.1499368195 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 Path4https://returnpath.com/wp-content/uploads/2015/04/RP-Subject-Line-Report-FINAL.pdf, 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 linesAverage read rate for subject lines containing this keyword
Still time33.73%
Limited time14.93%
Expiring16.60%
Last chance16.71%
Now15.75%
Expire16.69%
Hurry19.01%
Extended9.20%
Running out9.92%

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: Mailchimp2https://mailchimp.com/resources/catchy-email-subject-lines/ 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!

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.” Mailchimp2https://mailchimp.com/resources/catchy-email-subject-lines/ 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!”

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:

  1. “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.
  2. “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!).
  3. “Psst… Here’s a freebie.” People love the word “free,” but did you know the word “freebie” works even better2https://mailchimp.com/resources/catchy-email-subject-lines/? Add this to your email, but please make sure to make the freebie worth it (or risk getting unsubs!).
  4. “So. Many. Deals… Find Something AMAZING Now 💸”  
  5. “You’re a Perfect Fit For [insert opportunity here].”  
  6. “Save up to $10/month for life”  
  7. “Hey, you forgot this—here’s your 20% off!” 
  8. “Get a [adjective] $20 off your next order.”  
  9. “Ready for a Game-Changer?”
  10. “Limited Time Offer: 30% Off Your Next Purchase!”
  11. “Solve [Problem] with This One Simple Tool”
  12. “Last Chance: Don’t Miss Out on This Deal!”
  13. “How to Achieve [Desired Outcome]”
  14. “Exclusive Offer: Buy One, Get One Free Today Only!”
  15. “Join the Revolution: Be the First to Experience [Product/Service]”

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:

  1. “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.

  4. “Following up on…” 
  5. “Referred by [friend] — [name]”
