Email Subject Lines: Best Practices, Tips, and Examples

Subject lines can make or break an email campaign, and while we wish there was one tried-and-true method to subject line success, stellar subject lines vary between brand, audience, and email campaign. There are, however, a few general guidelines that can set you up above the rest.

Before we get into the 39 best email subject lines that have rocked our inbox this year, take our quick, true-false quiz below to make sure your subject line foundation is solid.

To help guide your subject line strategy and inspire your own subject line copy, look through our list of 39 email subject line examples that persuaded us to open the emails. But first, let’s take a peek at a few email marketing subject line best practices.

Email marketing subject line best practices

Do: Keep it short (around 3 words)

Here at Twilio SendGrid, we’ve analyzed emails sent through our system, and our subject line data reveals that recipients prefer and will be more likely to open a subject line when it’s 3 words. Does that mean if you think you have the perfect subject line at 4 words, you should change it around completely? No, guidelines and trends are just that—they are not a universal law.

Still finding yourself in a writer’s block? Consider putting a spin on puns or easily recognizable phrases. Although these phrases are trite and lazy by themselves, when you alter or put a personal spin on a pun applicable to your brand or service, you usually catch people’s attention because they were expecting to read something else.

The following subject line from a smoothie delivery company puts a twist on the phrase, “No way, Jose.”

The accompanying email included cocktail recipes that you could make with its smoothies—one of which is a rose smoothie(!).

Yass way, I am opening that email.

Do: Write the subject line last

You may have an idea for your subject line when you’re pulling together an email campaign. But until you’ve selected all copy pieces and written accompanying snippets and headlines, you won’t have the full picture of what you’re really trying to explain. And as a result, distilling your content into one line of text will prove quite challenging.

There are, of course, exceptions to this tip. Sometimes, a flash of brilliance occurs and the subject line almost writes itself before finishing other steps. For cases when that doesn’t happen, wait until you’ve finalized every other piece of content before attacking the headline or subject line.

Do: Make it specific and urgent

Think of the subject line as your first CTA or touchpoint with your recipient. If you don’t draw them in right away, you’ve lost them. And while humor and wit are usually rewarded, keep in mind that you need to give your recipient some sort of (accurate) taste of what’s inside.

To achieve this, try to use action verbs that resonate with your audience as much as possible. Verbs are a writer’s best friend because they help you do more with less—something that will always play in your favor.

I recently received an email from Strava that draws on the inherently competitive nature of Strava users and uses an appropriate verb in its subject line:

How fast can you run a mile?

Do: Experiment

No single (legal) email list is the same, which means that you won’t know how your audience will react to your subject lines until you actually send them something. Fortunately, subject lines happen to be some of the simplest email components to test.

Consider sending 2 or more subject lines to different segments of your email list. One subject line may be a bold subject line that pushes the envelope, while the other could be a more traditional and literal subject line. The options are endless. For more on how to test and experiment in your campaigns, read up on some common questions and answers to A/B testing .

Don’t: Overdo it with . ALL CAPS, and other frills

We’re all likely guilty of adding in exclamation points or being tempted to WRITE IN ALL CAPS TO GET OUR POINT ACROSS. We use these language tools to help us emphasize, but often these tactics lose or agitate the recipient.

Tread extra lightly when considering hitting your caps lock or using excessive exclamation points or other symbols.

Allow your subscribers to react to the meat of your copy instead of the frills.

One modern exception to this rule, depending on your industry, is using emojis. For some campaigns (such as marketing to millennials), it can work great. For others, it falls flat. See the previous tip about testing to find the right balance for your email program. Emojis also allow you to use fewer characters, so if it’s working for your engagement, then go for it.

Do: Have fun

Finally, don’t forget that writing subject lines can be fun and a great place to explore/try new things with your writing style. Subject lines are short but mighty nuggets of content that set the pace for all following email engagement events. So take your time, give the subject line some thought, and follow the tips above (but know what works best for you).

39 email subject lines that rocked our inbox

1. Morning Brew – ☕️ Thank you, Beyoncé

Morning Brew continually excels at writing relevant and short subject-line copy. This 3-word, 1-emoji subject line builds enough interest by featuring music icon, Queen B. Don’t mind if I find out more.

2. Lucky Brand – Welcoming you with a sweet treat inside

Lucky Brand’s welcome email goes beyond the standard greeting, enticing recipients to open the email with a special treat (aka discount code!).

3. Postmates – $15 to get over the hump

Ideally, aim to put the deal first in the subject line so that recipients see at first glance that they’ll get $15 toward their Wednesday order. The word “hump” and camel emoji help differentiate this promotional email , making it stand out from the others in the inbox.

4. Medium – Tick (bite), tick (bite), tick (bite)

After a weekend spent in the summer outdoors, this timely subject line made my skin crawl. Evoking that much emotion through a subject line is hard to do and led me to open an email all about a tick epidemic. Yikes.

5. Robinhood Snacks – A cannabis CEO gets fired by a beer CEO

Oh, the drama! The intrigue! How could you not open this email to find out more?

6. Yelp – Denver – Pulled pork, ribs, brisket, sauce, and stretchy pants required

While this subject line is on the longer side, you know exactly what to expect when you open the email. And when opened, you aren’t disappointed with the barbecue recommendations or surprised by the stretchy pants requirement. The subject line is your window to show the recipient exactly what you’ll share with them. Don’t disappoint by saying one thing in the subject line and showing another in the email.

7. REI – Wild places. Wilder women.

I love this simple, alliterative subject line with its call to adventure. REI (most likely) segmented tits contact list to send this email to its female contacts. Even this simple amount of personalization helps engage contacts and increase your email open rate.

8. Rent the Runway – You left this behind …

This subject line may be simple, but it’s effective. Life often distracts us from our purchase plans, so effective abandoned cart emails help get our shopping addiction back on track.

9. Duolingo – You’re on a 2-day Greek streak! Make it 3?

By focusing on my current accomplishments and what I could achieve next, Duolingo reminds me to open the app and engage with its program.

10. Efficacy Clothing Company – Vacation mode: On

You don’t have to be a large company to have awesome subject lines. This small clothing company quickly (and simply) engages recipients at the beginning of summer with a mode we all understand. Check out this article for more summer email ideas .

11. Airbnb – Your home awaits: Romantic Apartment – near Acropolis

Here’s another unique reminder. Instead of simply saying, “Don’t forget about this home,” Airbnb puts a romantic twist on the update.

12. Society6 – You’ve scored 15% off (but it won’t last)

This is a great example of creating urgency without using exclamation points or the words “today” or “now.” It’s a more subtle and effective way of engaging your recipients.

13. Winter Park Resort – You’ll thank yourself later …

We were convinced not only to open the email but also take a day off work to enjoy the 16” of fresh powder. You’re right, Winter Park Resort, we did thank ourselves.

14. Winc – Jillian, enjoy your personalized recipe pairings!

You don’t always have to be subtle with your personalization . Letting your recipients know that you’re trying to give them an individualized experience with your brand is a great way to show you care.

15. Peloton – Find this year’s goal

We all slip a little on our workouts in the midst of holiday madness. So to help you get back on track in the new year, Peloton doesn’t even suggest working out. Nope, it just suggests setting a new goal. It’s all about those baby steps toward engagement.

16. MacPaw – Just a thank you note (and a 30% off coupon)

This subject line is simple, but it’s also compelling. Thanking your customers is a great way to show your appreciation, and a thank you gift to go along with it takes the appreciation to another level.

17. Casper – Best place to catch the fireworks? In bed.

This 4th of July email got me with its cheeky subject line. While so many other emails were recommending places to watch fireworks or grill recipes, Casper sticks to what it knows—mattresses. And while this article does focus on subject lines, let’s give the preview text a shoutout too. The preview text, “Get 10% off your mattress order,” gives recipients even more of a reason to open the email.

18. Asana – You just got assigned a task, now what?

This direct subject line may not be the snazziest, but it sure is useful. If you’ve just started using a product , a “Now what?” type email is a great way to help onboard your customers each step of the way.

19. Felix Gray – Still have FSA dollars?

Since you lose FSA dollars at the start of a new year, this timely reminder is very useful to recipients who would much rather spend those funds on a pair of Felix Gray glasses.

20. Framebridge – Goodbyes are hard …

This short and (bitter)sweet subject line gets to the point in just 3 words: we’re going to say goodbye unless you decide otherwise. Reengagement campaigns are a great email marketing strategy to win back some of your subscribers and scrub your email list of subscribers who are no longer interested.

21. Artifact Uprising – Making it for Valentine’s Day? Order by Sunday!

This subject line is a soft reminder that Valentine’s Day is just around the corner, giving you the space you need to decide what you want to get for Valentine’s Day while pointing out that limited time remains. For Valentine’s Day and spring campaign ideas, check out this article .

22. Chubbies – Gilligan’s thighland

Preview text: Starring none other than Julieigan in their debut.

This subject line is silly fun. Meshing my name with Gilligan in the preview text was a great way to personalize the email and make me smile. Adding humor to your emails isn’t an effective method for every brand, but it’s worth testing to see if your recipients connect with it.

23. Thursday Boot Company – “Why I’ll live in these boots till I die.”

This emphatic statement is even more powerful by the quotes that surround it, leaving you to believe that someone actually spoke these words. It was enough to pique my curiosity, so when I opened the email, I was thrilled to find a review from a customer writing this very line.

24. Headspace – Ready to meditate?

This welcome email jumps right into the purpose of the app, and gets into actually welcoming the recipient in the body of the email. It’s a refreshing approach to the welcome email subject line.

25. Clark from InVision – A good pizza advice

OK, I’ll admit it, I’m a sucker for puns. But what does a pizza have to do with a design company? The subject line made me curious enough to open and find out the relationship between pizza and design, (which, by the way, has to do with learning from Domino’s designer ).

26. Strava – There’s still time to get moon dust on your shoes

In celebration of Apollo 11’s 50th anniversary, Strava sent an email appealing to its audience’s sense of adventure and drive to achieve the impossible. This subject line motivates recipients to not only open the email but also dust off their running shoes for this new challenge. #challengeaccepted

27. The Hustle – Are meetings even necessary?

Daily newsletters need to continually keep readers on their toes to drive interest. Posing a question like the one above makes us stop for a second to think and click-through to learn more.

28. Society6 – Quiz: What’s your home decor style?

A que stion and quiz can be a great way to engage your recipients. While the subject line poses the question, the body of the email provides a quiz with the answers. I not only opened the email but also clicked through to take the quiz and find items in my decor style.

29. Postmates – Search with emojis on Postmates ‍♀️

Emojis alongside text in this subject line show the new product update. Can you try telling a story with emojis in your subject lines?

30. Nordstrom – Self-care must-haves

Nordstrom sent this email in March when COVID first shut down cities around the country. During this period of high anxiety and shot nerves, Nordstrom’s “Take a wellness break” email was a welcome reminder.

31. The Muse – Tech tricks to make WFH so much easier

Working from home was an adjustment for everyone. The Muse recognized the challenge and related to subscribers by meeting them with what they needed—a few tech tips to make the transition a bit easier.

32. Birdies – Enjoying the indoors

With the preview text, “How we’re making the most of staying home,” Birdies offered ideas for quarantine activities, providing value to subscribers while showing off their comfy work from home slippers.

33. Get Lit(erary) – Cheers to you, fellow book lovers

The literary newsletter from publishing company Simon & Schuster knows its audience. Cheers-ing fellow book lovers with monthly reading recommendations and keeping us occupied during a time when entertainment is essential.

34. VCA Firehouse Animal Hospital – Don’t forget! Jade’s appointment at VCA is Monday, 4/27/2020

Although a little long, I like that it provides all of the need-to-know details in the subject line. Pair this with an SMS reminder the morning of, and there’s no way I’ll miss this vet appointment!

35. Allbirds – Meet our first running shoe

Allbirds does a good job of keeping its subject line copy simple and straightforward while still creating intrigue. There isn’t any guessing as to what this email is about, but I will definitely click to learn more about this running shoe.

36. Udemy – 4 skills for productive remote working

Recognizing that full-time remote work is challenging for many, Udemy provides value to its subscribers by offering work-from-home tips.

37. Canva – Add GIFs to your design in a single click

Canva encompasses an awesome product update in a single line of text. Who wouldn’t want to find out more?

38. – 5 cocktail recipes to try at home

With bars closed earlier this year, this instructive email came at the perfect time while simultaneously offering us an interesting activity and quenching our thirst.

39. SendGrid Blog – It’s an inbox party, and you’re invited

We couldn’t write a blog post on subject lines and not feature one of ours. We like to have fun with our subject lines. See if a playful tone works for your brand! And (shameless plug), subscribe to our blog to receive email-related tips and fresh content in your inbox every other week.

Additional tips for writing subject lines

We’ve reviewed 39 awesome subject lines, but how do you come up with equally attention-grabbing content? To write noteworthy subject lines, we recommend that you:

  • Use action verbs: Action verbs help capture the attention of subscribers. Avoid writing in a passive voice (using words like “was” or verbs with “-ed”) to keep your subscribers engaged.
  • Keep it short and sweet: A general rule of thumb is to limit your subject line to 5 words or less. This is easier said than done, but a shorter subject line is less likely to get cropped on mobile apps. It also makes it easier for your recipients to quickly understand the purpose of your email.
  • Avoid excessive punctuation, capitalization, or emojis: Excessive amounts of anything in a subject line can come off as annoying to a recipient and are red flags to mailbox providers. Don’t get carried away with those exclamation points—you’ll more likely end up in the spam folder.
  • Continue to test: With so many email service providers (including Twilio SendGrid), you have the ability to A/B test your subject lines to see what your audience engages with most. This is such a great tool to learn more about your audience and what they like to see in your emails.
  • Know your audience: There’s no point in trying to please everyone. If you know who you’re talking to, you’ll have a much easier time pinpointing a subject line.
  • Lean on what’s going on: Whether it’s the 4th of July, a thank you gift for Christmas, or a welcome email when you sign up for a newsletter, leverage holidays to make your email timely for your recipients.
  • Provide value: Ask yourself, why is my email useful? Why would someone want to read this email? Try to incorporate the “why” into the subject line. If your subscribers see that your email will help them out in some way, they’ll want to open it.

Email Marketing 101 for Your CBD Brand

Due to the number of restrictions on advertising opportunities, such as paid search, for cannabis or cannabis-related brands, email marketing tends to be one of the more popular ways to reach your customers. (It should, however, be noted that many of the prominent platforms have policies against using their platform to market federally banned substances, such as cannabis.) Email campaigns are also inexpensive compared to other marketing strategies and allow businesses to communicate directly with their audience and keep them both informed and engaged.

Like other branches of marketing, email campaigns should be designed strategically. You’ll want to follow a number of best practices to ensure that you are maximizing the benefits of your email campaign.


Collecting and documenting all the necessary and important information about a contact is key to building a meaningful contact list. A great way to gather information from new and potential customers is by giving them something for free .

With the cannabis and CBD industry being so new, knowledge is one of the best things to entice people to sign up for newsletters or provide their information. An example might be including offers on your website for a free e-book about the differences between CBD and cannabis when people sign up to receive your emails. Allowing users to subscribe to a newsletter of choice (weekly/monthly or by topic, etc) is another way to build your list while collecting valuable information, such as the topics of interest of any given potential customers. This type of specific information also enables you to cater your emails to each segment of your audience.


CBD products have a variety of benefits and appeal to a variety of different people. Your customers are not all going to be responsive to the same type of product or appeal, the same way not everyone in your email list is going to react the same to the content you send out.

Tailoring email content and communication based on a set of traits, such as age, location, job position, status, etc. is a sure-fire way to get the types of responses you want, such as a purchase decision or membership sign-up.

Segmenting your email audience according to the interests of your audience makes it easier to determine what type of content and offers to send out. It also enables you to connect with them directly and therefore, drastically improve your open and click rates.


Some people may find monthly newsletters a nuisance and would rather only receive short email notifications about important information and updates or sales and exclusive deals. Others may want more frequent emails, such as a weekly news article or highlight of a product. Sending out different emails for each of these segments is an important way of showing your customer base that you are paying attention to their interests and, therefore, are truly aiming to serve them.

Finding the right rhythm for your business and your audience is an important way to actually retain that actively engaged customer base. As a brand, you will want these customers to actually open and click through your emails, or even potentially purchase products as a result of the email. Think about your specific audience and their preferences, and match your rhythm to theirs.


From your subject line to the email preview to the actual message content itself, your email should be written in an engaging manner.

The subject line is particularly important as it is one of the first impressions your email has on its recipients. Crafting a catchy subject line can determine whether or not your contact is compelled enough to click through. A good rule of thumb when thinking of a subject line is to use concise language that makes some indication about the content of the email.

According to Hubspot , “up to 77% of email opens taking place on mobile”, so using subject lines with fewer than 50 characters ensures that the people viewing your emails are able to read the entire subject line in a glance.

Beyond that, your email should be timely and relevant to the audience while also creating a sense of importance that makes them feel special. A great way to accomplish this is by using personalization tokens, such as a name or a location, in parts of the email to forge a stronger connection. Proper phrasing can also go a long way in building loyalty amongst your customers. For instance, an email about “an exclusive offer for you” is far more likely to perform better than one that is about “a sitewide offer”. The exclusivity felt from certain phrases compels readers to convert better on your emails.

Overall, newsletters and emails should be used to highlight whatever aspect of your business is critical for your success. For instance, if attending trade shows and expos are driving leads, send emails to promote your attendance and booth presence at those events. If you have a successful hero product, focus on the appeal of that product to make customers reach for it on shelves or online. If it is knowledge and experience that your brand brings to the industry, share blog posts and news articles via links to blog posts or credible resources.

Sharing your brand and its pillars of success will cement your authority within the industry and have your audience turning to you for every question or product purchase they have.

100 Email Subject Lines that Demand to be Opened

Your open rate is arguably the most important email marketing metric to monitor, after delivery rates of course.

Yes, you want your subscribers to convert into buyers. However, they actually need to open your emails. That’s why it’s crucial to write the best email subject lines.

In this post, we provide the best email subject lines of 2019 for inspiration, along with some email subject line best practices to get you started.

Email Subject Line Best Practices

69% of people report emails as spam based purely on the subject line. Meanwhile, 47% of subscribers will decide whether to open your email based on the subject line alone.

You have too much riding on your subject line to throw a quick bland description up and call it a day. Use these email subject line best practices to write copy that makes the mark.

  • Keep it short: Five words or less and under 40 characters (to account for mobile users).
  • Use actionable language: Action verbs like “shop” or “help” can go a long way.
  • Create urgency: Let readers know the time is now.
  • Use sentence case: You’re having a conversation with your subscribers and most people don’t write peer-to-peer email subject lines in title case.
  • Don’t be afraid of emojis: They can help shorten your email marketing subject lines and boost open rates by 66% or more.
  • Avoid spam: It’s not as easy as it sounds and what qualifies as spam constantly changes.
  • Segment your list: Don’t send the same subject line to your entire list. Personalize your content to improve open rates and conversions.
