60+ Email Subject Line Examples From Awesome Brands

Let’s cut right to the chase. We’ve combed the internet looking for some really good email subject lines — and here’s the result. Some are cool, others are funny, and some resonate with the brand image.

Some of these email subject lines are great for sending shopping cart abandonment emails, and others make for the perfect follow-up.

1. “Google sees smartphone heroics in Oreo. It’s The Daily Crunch.” — This is an interesting subject line example from TechCrunch, a newsletter that keeps people updated about the latest news and developments in the world of technology. So, using the words’ daily crunch’ keeps you abreast with updated information about technology, so you know you gotta read it.

2. “Where to Drink Beer Right Now” — (Sent at 6:45 PM on a Wednesday): Eater Boston couldn’t have timed this better. After a busy day midweek, this can be the perfect thing to wake up to and ease out a bit.

Email subject line example — *Source: Neil Patel*

3. “Uh-oh, your prescription is expiring.” — Using conversational words like “uh-oh” invokes the fear of missing out. Here, Warby Parker used this line to attract customers to buy glasses. It’s a truly creative follow-up email subject line.

4. “Best of Groupon: The Deals That Make Us Proud (Unlike Our Nephew, Steve)” — Sarcastic and funny subject lines can pique the interest of readers. Groupon uses this strategy to the best.

5. “*Don’t Open This Email*” — When we are told not to do something, we tend to be more curious to open the content and read. This is what Manicube used in their marketing email subject line. But be careful — only use this subject line when the reader is familiar with your brand or service. Otherwise, they might just block you!

6. “What They Eat In Prison,” “DO NOT Commit These Instagram Atrocities” — A catchy language always urges the reader to look forward to exciting content. Thrillist uses catchy sentences like this in their subject line to entice readers.

7. “Black Friday shoppers are the worst customers” — This came in a LinkedIn Pulse newsletter, promoting an article one of its users wrote on the topic of holiday marketing. Intriguing facts and figures make the reader want to open the email.

8. “10 bizarre money habits making Millennials richer” — Subject lines that are leading will always urge the recipient to know more about the subject. Refinery29 uses leading subject lines to make the email marketing subject lines more appealing to their followers.

9. “Not Cool, Guys” — BuzzFeed is known for its unique and exciting content. Sometimes, they use a combination of the subject line and preview text to make it conversational and friendly. For example, the preview text that followed this was “Okay, WHO left the passive-aggressive sticky note on my fridge? Honestly, who acts like this?”

10. “Is this the hottest career in marketing? ” — Digital marketers used this curiosity-inducing subject line to let readers know what’s interesting inside.

11. “Free (Cool!) Clothes Alert” — Clover uses visual content like emojis to lure readers into opening the email. Use this sparingly and only when it is relevant.

12. “You free this Thurs at 12 PM PST? [guest blogging class]” — Mary Fernandez used personalization to reach out to new readers and existing followers. Personalization should be a part of a great subject line as it works wonders and urges the recipient to open the email as it makes them feel special.

13. “1,750 points for you. Valentine’s flowers & more for them.” — When you read this line, you’ll immediately want to know who the flowers are for. This prompts you to read the body. Cryptic follow-up email subject lines like this are fantastic and entice readers.

14. “Rock the color of the year” — Etsy, the e-commerce website, was able to promote a product solely based on color. We’ll want to know what ‘the color of the year’ is, right?

15. Sometimes, direct newsletter subject lines also work best. For example, “[Company Name] May 2005 News Bulletin!” or “Eye on the [Company Name] Update (Oct 31 – Nov 4).”

16. “As You Wish” — UncommonGoods knows its buyer persona and sends emails based on its customers’ wish lists or interests. This subject line is based on the movie ‘The Princess Bride.’

17. “Everything you wanted to know about email copy but was too afraid to ask” — CopyHackers uses one of your fears or pain points to urge you to take a quick look at the email.

18. “The price dropped for something in your cart” — These retargeting email subject lines can prompt you to visit your cart once again or complete some unfinished purchases.

19. “Tonight Only: Get this NOW before it’s gone…” — Resisting FOMO or Fear of Missing Out is difficult. Violet Grey uses this with an added incentive to increase email open rates.

20. “New Video: (Topic)” — An effective email campaign should not only increase sales but also provide value to customers.

21. “Yes, this is a fundraising email” — (from Al Franken), and …

22. … “Hey” — (from Barack Obama) These two straightforward and seemingly “boring” newsletter subject lines performed the highest out of 40 million emails, with open rates between 60-80.

23. “Products the celebs are wearing” — Sephora used this celebrity branding and vanity subject line to hit readers’ emotional quotient and make them open the email.

24. “Learn a language with only 5 minutes per day” — Offering a solution to a problem or addressing a pain point is a good strategy when writing an email subject line. Duolingo gave a great offer while trying to solve a problem.

25. “We Need To Talk…” — A recent email marketing campaign by PPC Protect saw an impressive open rate of 63% using this simple subject line. Not only does it make the email look important, but it also triggers the reader’s curiosity.

Tips for Writing Awesome Subject Lines for Emails

Here’s how you write a great email subject line.

Curiosity

Curiosity is something that works wonders. Add text or content that will invoke interest in the reader’s mind. Questions or intriguing one-liners will usually allow a reader to be more curious. “What’s inside that everyone’s talking about?” could make the readers want to know more.

Urgency

Using urgency is a classic approach and generally works because it compels the reader to take immediate action. Examples include, “Hurry, only a few hours left!” or “Offer expires tonight!” In such subject lines, the feelings of urgency are stirred in the readers to click before it is too late. But let me give you one word of caution: don’t overdo it.

Too much urgency can feel pushy and even come off as spammy. Try A/B testing different approaches to find the right balance for your audience.

Emoji usage

Emojis can add personality and help subject lines stand out. For example, a “party” or “light bulb” emoji can make an email pop. However, use them sparingly—a recent study shows subject lines without emojis perform slightly better (52.94% open rate vs. 47.06% with emojis). Balance is key, and A/B testing can help determine what works best for your audience.

Mobile optimization

Most people open emails on their mobile phones. As such, subject lines have to be mobile-friendly. In most mobile phones, the subject lines get cut off if they are long. Therefore, use short subject lines—less than 50 characters—to be effective, clear, and appear appropriately even on a small screen and still grab attention.

A good rule of thumb is to have subject lines A/B tested to see where adjustments need to be made.

Relevance

Subscribers want timely and trendy information, which you should be giving. This idea should be leveraged while designing better subject lines as well. Trendy topics or trendy headlines should be used in newsletter subject lines to keep readers interested.

Personalization

Adding a personal touch to your email subject line can make your recipients feel valued and more likely to engage. It’s a powerful strategy for building strong relationships and driving more leads. You can boost open rates and cultivate customer loyalty by making your emails feel more personal.

Celebrity branding

Use a familiar name so people can identify it right away. Personality traits of celebrities can invoke curiosity in the recipient to open the email.

Bonus tips for leveraging emotional psychology to write subject lines

Use emotional psychology to write a good email subject line. They can boost your email open rate. Try these three strategies: scarcity, excitement, and humor.

Scarcity: Scarcity means a product or service has a limited supply. It urges readers to act quickly before it runs out. Subject lines such as “Ready to go, only five spots left—hurry up!” or “Stock is limited, get yours now!” capture the essence of scarcity.

Excitement: Create anticipation in your subject line by advertising something new or exciting. For example, a good subject line such as “Brace yourself; something mind-blowing is coming!” will create excitement and boost your email open rate.

Humor: Using humor in your email subject line can make it more memorable. Or such simple sentences as “Sorry, did you not see this?” add an element of cuteness that draws attention to it.

The best way to understand which emotional trigger works better for your audience is by A/B testing. Look at your different subject lines through urgency and interest levels, and evaluate the strategies you used to improve them. For example, consider the variation in performance of “Get 20% off TODAY ONLY! (urgency) and “What does it contain that is so irresistible? (curiosity).

Using such strategies and effective techniques, you can easily create attention-grabbing, action-inciting subject lines that boost your email open rate.

Best Practices When Writing Email Subject Line

In writing email subject lines, there are certain things you can do to improve your click-open rates and stand out in a crowded inbox. Here are some subject line tips for creating a good email subject line for your email marketing campaign:

1. Keep it short and engaging, and use emoji sparingly

The best email subject lines are between 6 and 10 words or 40 and 60 characters. “Why?” You might ask.

Ifr email subject line is displayed on a mobile device; it will be cut off if it is too long. Also, if it is longer than the proposed length, your recipients might scan it without reading it.

Shorter and catchy email subject lines have a higher open rate, and emojis can make your subject lines stand out. Additionally, funny email subject lines with emojis can make your emails stand out.

However, cold email subject lines are an exception as using emojis in them can seem unprofessional and trigger spam filters.

2. Be clear and specific: use actionable language

A great subject line should tell your recipients what they’ll find in the email. Do not use vague words, which can reduce engagement and lead to confusion.

Encourage your audience to take action by using action phrases like “Unlock” and “Discover.” You can also use call-to-action language in the subject to set the tone for what your recipient needs to do next.

3. Personalize when possible

One of the few ways to create a mutual connection with your recipient is personalization. Personalized email subject lines can increase email open rates by making the message relevant to the recipient.

You can personalize the subject line by using your recipient’s name. You can also use information specific to their past purchases, location, or interests.

EngageBay’s email marketing software lets you easily segment your audience and automate personalized subject lines, ensuring each email feels tailor-made for your customer.

4. Pique curiosity and avoid spam trigger words

In your subject lines, tease the content of your email without giving it away. You should ensure that your subject line makes the recipient curious.

By making the recipient curious, you encourage them to open the email for more. However, you should balance the curiosity with clarity so that recipients won’t view your email as misleading.

Conversely, do not use words that might trigger spam filters. Words like “win,” “Guaranteed,” or “Act Now” can cause your email to land in the spam folder.

5. Test with A/B testing

A/B testing is doubly important for sales emails. It scans through different variations and ultimately produces an effective subject line, aka the best-performing subject line.

Whether they are funny subject lines or subject lines for follow-up emails, A/B testing will test them element by element. The elements are the length, tone, and word choice—all to see what resonates well with your audience.

The valuable insights obtained are used to refine your future subject lines.

EngageBay has an A/B testing feature that you can use to find the best email subject line and get your desired outcome.

6. Avoid using ALL CAPS

Study shows that 85% of recipients prefer subject lines in lowercase. Fully capitalized subject lines look spammy and will be ignored by readers. Look at the example below:

WHAT IS THE BEST WAY TO SPEND THIS HOLIDAY??

Don’t you get the feeling that someone’s screaming at you? Instead, use simple and engaging language to get your reader’s attention.

14. Attract readers, not a spam filter

Another challenge for an email marketer is ensuring the email doesn’t land in a spam folder. Email marketing success largely depends on email deliverability, and your subject line impacts the delivery rate.

A few studies have revealed that certain use of words or phrases triggers the spam filter because they are not email-friendly. Your email deliverability rate can significantly improve when you avoid these triggers.

So, what are those phrases considered spam? Emails containing content associated with free gifts, marketing gimmicks, schemes, or promises are usually flagged as spam. You can also use MailMeteor’s free email spam checker to make sure your subject line and email copy are good to go.

How to Measure the Success of Your Email Subject Lines

Measuring the success of email subject lines is essential to understand their impact on email open rates, click-through rates, and conversion rates. Here are some key metrics to track:

Open rate: This metric indicates the percentage of recipients who open the email based on the subject line. A higher open rate suggests the subject line was compelling enough to grab the recipient’s attention.
Click-through rate (CTR): The CTR measures the percentage of recipients who click on a link within the email after opening it. This metric helps you understand how well the subject line and email content drive engagement.
Conversion rate: The conversion rate tracks the percentage of recipients who complete a desired action, such as purchasing or filling out a form. This metric is crucial for evaluating the overall effectiveness of your email campaign.
Bounce rate: The bounce rate represents the percentage of emails returned to the sender due to an invalid or non-existent email address. A high bounce rate can negatively impact your email deliverability and sender reputation.
Spam complaint rate: This metric shows the percentage of recipients who mark the email as spam. A high spam complaint rate can harm your sender’s reputation and reduce the chances of your emails reaching the inbox.

To measure these metrics, you can use email marketing analytics tools like Google Analytics or email service providers like Mailchimp or Constant Contact. These tools provide valuable insights into your email campaign performance and help you identify areas for improvement.

Additionally, A/B testing is a powerful technique to compare the performance of different subject lines. You can determine which one resonates better with your audience by sending two versions of an email with different subject lines to a small segment of your email list. This data-driven approach allows you to refine your subject lines and optimize your email marketing strategy.

By analyzing the performance of your email subject lines and making data-driven decisions, you can enhance your email marketing campaigns and achieve better results. Remember, the right subject line can significantly impact your email’s success, so it’s worth investing time and effort into crafting compelling subject lines that draw the reader’s attention.

FAQ

How do emotional triggers like FOMO or curiosity improve email open rate?

Emotional triggers target the psychological makeup of the readers to make them act and open emails. FOMO triggers the need for urgency in people to act quickly (like “Last chance! Only a few seats left!”). Similarly, curiosity triggers attention, which is used in phrases like “What do we have inside?”.

What are the best practices for A/B testing a subject line?

A/B testing involves trying out subject line variations, behavioral personalization, and timing to test which works best for the audience. For example:

Test only one variable at a time (change in length or tone).
Use peak time, such as Tuesday at 11 AM, to send the message.
Evaluate open rates and click-through rates to establish the most effective one.

How can I make my email subject line mobile-friendly?

Ensure you keep your subject lines within 50 characters to stop them from appearing shorter or cut off on mobile screens. Put the most important information first for it to be the first thing to be seen. Avoid complicated vocabulary so that the readers can easily understand it.

What are some examples of personalized subject lines to improve email open rates?

Make sure your email subject lines are relevant and personalized to include specific names or previous actions. Here’s how you can do it:

Before: “Look at our amazing new collections!”
After: “Hello [Name], we have selected a few items for you.”

What role do emojis play in improving email open rate?

Emojis help enhance the open rates by breaking the monotony of text, though excessive use may lead to spam burying the message. It is advisable to use only a couple of emojis to prevent it from appearing animated. A/B testing methods can be used to know how your audience responds to it.

What is the impact of urgency in subject lines on email open rates and reader engagement?

Urgency in subject lines is compelling in calling for action, but there is also a risk of abuse that can lead to spam reports. For example, one can create and use engaging subject lines like: “Hurry! This offer ends tonight!” encouraging readers not to procrastinate. However, use it cautiously, as overuse can make one sound desperate.
