I’d venture to guess you get tons of emails in your inbox every day.
From coupons to daily deal sites, from newsletters to your mother wanting to know when you plan to visit — it’s a lot to sift through, never mind actually open. The average click-to-open rate is a slim 14.1%, so you’re not the only one.
What does it take for someone to actually open an email? Often, it’s the subject line. After all, it’s your very first impression of the email. From that first impression, you’ll do your best to judge the content inside.
So what makes a good email subject line? It’s a message that conveys urgency, curiosity, personalization, and so much more. But it’s up to you to make that distinction of which fits best in your business offer and appeals to your audience.
Let’s take a look at a few examples that, old or new, we’re crazy about — plus what makes them so great. We have 100 awesome subject lines to offer you already, but read on for 50 more that we found eye-catching.
(While you’re at it, check out our Out-of-Office Email Generator to make your email address even more delightful to your contacts.)
Subject Lines for Retargeting
1. “We Saw You Checking Us Out 😏”
Sender: DollsKill
A clothing brand like DollsKill uses cookies to monitor what its customers have been eyeing. By sending an email subject line reminding them of items they admired can reel customers right back into their next purchase. The statement itself has a playful and conversational tone that comes off flirty, a reflection of its company branding.
The emoji also adds more fun and temptation to the message — reiterating that “you know you want to” feeling regarding items they have already clicked on before.
2. “Uh-oh, your prescription is expiring”
Sender: Warby Parker
Not too long ago, a HubSpot alum received this email two weeks before he needed to renew his prescription — talk about great timing. And when your eye prescription is expiring, it happens to be an excellent time to upgrade your glasses. By sending an email at the right time, Warby Parker increased its chances of this email getting opened.
But timing isn’t the sole reason we included this example. This subject line is brilliant because it appeared at the right time and with the right tone. Using conversational words like “uh-oh,” keeping the subject line sentence case, and leaving out the period in the end, the subject line comes across as helpful and friendly — not as a company trying to upsell you.
3. “The timer’s going off on your cart!”
Sender: King Arthur Flour
Similar to Warby Parker, this subject line makes use of urgency. If I don’t take action on my King Arthur Flour shopping cart — like actually buying the items — it will be cleared, and I’ll have to start all over again.
Okay, so maybe this is a low-risk scenario. But when it comes to my baking goods, I personally don’t like to take any chance of forgetting what I was going to buy. That’s where the personalization aspect of this subject line comes in: King Arthur Flour — especially its online shop — tends to attract both professional and home bakers who take all things culinary a bit more seriously than, say, someone who only buys flour on occasion from the supermarket. And wouldn’t you know? Those are the same bakers who probably don’t want to spend time building their shopping carts from scratch.
The moral of the story: Know your audience when you’re writing email subject lines. Is there something that they take seriously more than others? If so, incorporate that into your copy.
4. “What Did You Think? Write a Review.”
Sender: REI
I received an email with this subject line about a week after buying a portable stove at REI. I had just gotten back from a camping trip, too. It was perfect timing for them to ask me what I thought of it.
Companies ask satisfied customers to write reviews of their business all the time. But when you specifically send these requests to the people who just purchased something from you, you’re being smart with your mailing list and reaching recipients whose interest is still warm.
Another reason this subject line works? It’s not expecting a good review. REI is genuinely asking me what I thought of the stove I bought. Maybe I hated it (though I didn’t). The company just wanted me to speak up.
5. “A Sneak Peek for VIPs Only.”
Sender: Serena & Lily
Loyal subscribers can preview clothing collections via email, as seen here with Serena & Lily. By offering a “sneak peek”, customers know they have more exclusive access and will want to click open the email to see what they want before the general public can see it.
This concept keeps the customer relationship alive and coming back for more if the email marketing is done right.
Straightforward Email Subject Lines
6. “👗 Free (Cool!) Clothes Alert 👖”
Sender: Clover
First of all, we have a not-so-secret love for emojis in email subject lines. Personally, I’m partial to turquoise — so when I see an email implying that I might somehow be able to obtain free turquoise clothes, chances are, I’m clicking.
That’s part of what makes this subject line work. It draws the recipients’ eye by using visual content (emojis), and it hints at an offer of something free. That hint is an incentive to open the email because there’s something to gain inside.
7. “🐶 Want a Custom Emoji of Tullamore & 6 Months FREE Walks? Book a Walk Today for Your Chance to Win!”
Sender: Wag!
For reference, Tullamore is the name of my colleague Amanda Zantal-Wiener‘s dog. And the subject line she received, written above, is another winning example of perfect emoji placement — especially when it’s a cute dog.
Here’s a great example of how personalization goes beyond the email recipient’s name. Wag!, an on-demand dog-walking app, includes the names of its customers’ pets in a portion of its email subject lines. But this type of personalization is more than just a first-name basis. If there’s anything my colleague Amanda loves more than free stuff and baking goods, it’s her pup. Wag! knows that, and by mentioning Tullamore by name in the subject line — in tandem with an offer, no less — it caught her attention and piqued her interest.
8. “Best of Groupon: The Deals That Make Us Proud (Unlike Our Nephew, Steve)”
Sender: Groupon
It’s hard to be funny in your marketing, but Groupon’s one of those brands that seems to nail it again and again. After all, who can forget this classic unsubscribe video?
This subject line is no exception. The quip, “(Unlike Our Nephew Steve),” actually had us
laughing out loud. Why? It’s completely unexpected. The first part of the subject line looks like a typical subject line you’d get from Groupon, highlighting a new deal. The parenthetical content? Not so much — making this one a delightful gem to find in your inbox.
9. “Rock the color of the year”
Sender: Etsy
In six words, Etsy was able to promote a product solely by its color, and inform you that there is apparently a “color of the year.” The email is truly too intriguing not to open.
Etsy is an e-commerce website for user-created marketplaces, and the reason we were impressed by its subject line was because of the way it uses mystery to drive value into a suite of products. This email isn’t an invitation to buy clothing or jewelry; it’s an invitation to find out what the color of the year is.
10. “How to live at home 24/7”
Sender: Feather
If you’re anything like me, the COVID-19 pandemic had you wearing PJs from day to night, only changing when you had Zoom meetings at work. As a social distancing precaution, you likely used delivery services instead of going out and getting food on your own — which means that you were effectively living at home 24 hours per day, seven days a week.
This email from Feather, a furniture rental store, perfectly encapsulates a frustration many of us faced: How do you live at home 24/7 without feeling like you’re going crazy? With this subject line, Feather promises to help you find a solution by using furniture that makes it easier to stay at home for extended periods.
Try it: Use a “How To” subject line to tell recipients what they can achieve with your products. Then, in your email, include links to the products that will help them achieve those goals.
11. “Take $20 off your order of $25 or more”
Sender: UberEats
You don’t always have to make your email subject line flashy. In this case with UberEats, just the offer alone is good enough to make any hungry customer click.
Your product offering, if it’s appealing, can speak for itself in your subject line. Customers know they can take advantage of the opportunity in the body of the email, as I will for dinner tonight.
12. “Where to Drink Beer Right Now”
Sender: Eater Boston
Okay, you caught me: I’m a beer lover. But that’s not what hooked me here. The subject line arrived in my inbox just at the time I needed it: at 6:45 on a Wednesday evening. Absolutely. Genius.
Think about it: You’re just over hump day and want to decompress with a few coworkers after work. Right as you’re about to head out, you get a notification on your phone that says, “Where to Drink Beer Right Now.” Perfect timing makes this subject line something you can’t help but click on.
For your own emails, think about how timing will affect how people perceive your emails. Even if you send an email in an off-peak hour, you could get higher engagement — if you have the right subject line.
13. “1,750 points for you. Valentine’s flowers & more for them.”
Sender: JetBlue
It’s such a specific number … 1,750 … of course you’re going to open this.
Coming from an airline, an offering of “points” might as well be gold to someone who likes to travel. And, if that recipient also has a significant other, sending this email leading up to Valentine’s Day is a home run.
The best part about the subject line above is how particular JetBlue was about the number of points available. Instead of, say, “20% your next return flight of 1,000 miles or more,” this subject line gives it to you straight: 1,750 points, and all you have to do is buy flowers for your loved one. You’re already wondering how far you can fly with 1,750 points, I can tell.
14. “Free Oversized V-Neck.”
Sender: Los Angeles Apparel
I don’t know about you, but free is my favorite price when it comes to apparel. This brand has a simplistic and straightforward approach to its subject line by letting customers know what they can get in their next order.
And by keeping it short, it makes the subject line even more effective because the only other context the customer can see — is when they click open the email.
15. “Here’s that discount you wanted”
Sender: LAMODA
This subject line almost feels like it’s reading my mind. When I scroll through my endless emails, considering the businesses I want to buy from, I’m waiting for a discount or sale to be announced.
It’s straightforward and knows exactly what its customers want — key to getting clicks.
16. “3 ways to improve your Pins”
Sender: Pinterest
For those who love to curate their social feed, Pinterest is one of the best places to do it. For those trying to grow their following, they’re probably looking for all the advice they can get from the website itself.
Providing a numeric list of strategies to use in the ever-changing algorithm, it can prove useful to click on Pinterest’s emails periodically. This uncomplicated messaging in a subject line presents users with exactly what they’re looking for, right in their inbox.
Attention-Grabbing Email Subject Lines
17. “*Don’t Open This Email*”
Sender: Manicube
Ever been told to not do something? Being asked to refrain from something can actually have the opposite effect — you now want to do that thing even more.
That’s the strategy behind Manicube’s subject line. It’s a simple but effective way to make people curious enough to open your email. (Just be sure that the contents of your email have something worthy of that subject line.)
18. “Important Weather Advisory”
Sender: RCN
Any time we see a weather-related alert, our ears perk up. In RCN’s case, it isn’t just a way to lure recipients into opening an email. The subject line above is RCN’s way of updating its customers to potential power outages and driving attention to the brand that provides them with cable and Wi-Fi — even during inclement weather.
If you can hitch your email marketing campaign to an event you know people pay attention to, and have something helpful to offer in response, you’ll see your email open rate soar.
19. “What Can You Afford?”
Sender: Zillow
Imagine getting this subject line in your inbox from a website showing apartments for rent. It’s both exciting and encouraging (“Here are a bunch of apartments right in your budget. Yay!”), but also kind of competitive — pitting your cash against what the market offers. Would you click it? I certainly would.
Personalizing emails to cater to your audience’s emotions — for which there’s a broad spectrum when it comes to real estate — is key to getting people to open your emails. You don’t have to be a psychologist to know how to take advantage of them, either. In addition to principles like urgency, crafting an email subject line that implies scarcity is another great way to increase your conversion rates.
20. “As You Wish”
Sender: UncommonGoods
When writing emails, you should also think about the recognizable names and references that make people tick. For example, take this subject line from UncommonGoods forwarded to us from HubSpot’s Content Director, Corey Wainwright, who happens to be a die-hard fan of The Princess Bride. Apparently, “As You Wish” is a pretty big reference to that movie, so when she saw this subject line in her inbox, she just HAD to click.
Even though she knew the email was part of a larger-scale send, it almost seemed like it was tailored for her personally — after all, why else would it include a reference to Princess Bride in the title?
UncommonGoods knows its buyer persona like the back of its metaphorical hand. While it may not send emails to individual subscribers with references to their favorite movies in the title, it does have a general understanding of its subscribers and their interests.
21. “Not Cool, Guys”
Sender: BuzzFeed
We love BuzzFeed. If nothing else, its staff knows how to write great copy — and that sentiment includes an exceptional email marketing team. Many of my colleagues have signed up for BuzzFeed’s daily emails, and pretty much any day of the week, itwins for best subject line in their inboxes.
While there are a few of BuzzFeed’s subject lines here and there that aren’t anything to write home about, it’s the combination of subject lines and the preview text that is golden. They’re friendly, conversational, and, above all, snarky.
Here’s the text that followed the subject line above: “Okay, WHO left the passive-aggressive sticky note on my fridge. Honestly, who acts like this?” That conversational tone and snark pull us in over and over again — and it’s the preview text that completes the experience for me.
We’re not all equipped to be snarky writers, but most email platforms have the preview text easily available to edit. How can you use that little extra space to delight your customers (oh, and probably improve your email metrics)? Maybe you could use the subject line as a question, and the preview text area as the answer. Or maybe it’s a dialogue: The subject line is one person, and the preview text is another.
You get the idea. By using that space, you have more opportunities to attract new subscribers.
22. “DO NOT Commit These Instagram Atrocities”
Sender: Thrillist
No matter how humble people are, most don’t like to do things wrong … so why not play on that natural human tendency in an email subject line, especially if you’re in the business of helping clients (or prospective clients) succeed? Thrillist certainly does in the subject line above, and it makes the language even more vibrant by using do not — a great takeaway for B2B marketers.
Instead of using the typical contraction “don’t,” Thrillist spells it out and adds the all-caps for effect. That way, you’ll notice the subject line in your inbox, and then find it harder to resist clicking on it.
Think about how going negative in your marketing might be a good thing. For example, many of us have anxiety about looking silly and stupid, so figure out how you can play to those emotions in subject lines. Of course, it’s important to back up that subject line with encouraging, helpful content, so that you’re not just ranting at people all day.
Getting negative can get your subscribers’ attention — this subject line certainly caught mine.
23. “Everything you wanted to know about email copy but were too afraid to ask”
Sender: Copy Hackers
Here’s another great example of leveraging your audience’s full plate to your email marketing advantage. Who hasn’t refrained from asking a question out of fear of looking silly or out of the loop? Excuse me while I sheepishly raise my hand.
” … but were too afraid to ask” is one of those phrases that, to us, probably won’t go out of style for a long time. People seek insights from Copy Hackers — an organization dedicated to helping marketers and other professionals write better copy, as the name suggests — because, well, they have questions. They want to improve. And when that audience is too afraid to ask those questions, here’s Copy Hackers, ready to come to the rescue with answers.
What does your audience want to know, but might be too embarrassed to ask? Use that information to craft your content — including your email subject lines.
24. “Abra-cord-abra! Yeah, we said it.”
Sender: Quircky
This punny email subject line from Quirky is plain fun. We’re suckers for puns in the right situation.
What we like most about it is the second part: “Yeah, we said it.” The pun in the beginning is great and all — it refers to a new invention featured on Quirky’s site to help everyday consumers detangle their numerous plugs and cords — but the second sentence is conversational and self-referential. That’s exactly what many of us would say after making a really cheesy joke in real life.
Many brands could stand to be more conversational and goofy in their emails. While it may not be appropriate to go as far as Quirky’s subject line, being goofy might just be the way to delight your email recipients.
25. “🔥 Hot freebie alert! 15 free gifts, you pick 5.”
Sender: Shutterfly
Shutterfly, a company that allows you to print your photos on interesting products or other frames, gets visual with its subject lines by occasionally using an emoji. Due to the company’s nature and creative audience, the fire emoji in this subject line draws the eye without feeling desperate.
The email subject line also pops because it has a lot of buzzwords, including “hot,” “freebie,” “gifts,” and “alert.” In just one line, it can give the potential reader a good reason to open it, especially if they love using Shutterfly.
The content inside the email aligns perfectly with the subject line by announcing a freebie promotion. This strong alignment between the subject line and message keeps people from skimming the email.
26. “From chaos to calm ✨🏡”
Sender: Open Spaces
If you’ve ever had a cluttered home, you know how chaotic it can feel. Open Spaces takes advantage of that by suggesting how you’ll feel after you use the company’s products.
Its emoji choices also indicate how your home will look and feel: Sparkling clean. I’m not a huge fan of cleaning, but Open Spaces promises to make it easy in the simplicity of their subject line. The brand also proves that it knows its target customer exceedingly well — if you want to create “open spaces,” you likely won’t tolerate chaos in your home.
In the same way, try to allude to the feelings that your target customers want to feel, as well as their goals and inner desires. You can also let emojis speak for you. For instance, if Open Spaces had used the subject line “From chaos to calm: Get a sparkling clean home,” the focus would be off of the “from chaos to calm” piece, which is what readers most care about.
27. “Welcome Gift! Offer Inside 👀…”
Sender: EyeBuyDirect
When you subscribe to a business you’re new to, you’d hope you can get a perk before your first purchase. EyeBuyDirect makes its statement in a subject line that makes the prospect feel like subscribing was a good choice, and strikes curiosity.
Without specifying what the offer is, the customer has no choice but to click and see what they can take advantage of.
Now that we’ve covered the best subject lines in general, let’s dive into the best newsletter subject lines.
28. “Colorful things for colorful homes”
Sender: Baggu
I can’t speak for you but I’m a sucker for all things bright in color. And what makes this an attention-grabbing email subject line is that this brand is known for making reusable bags (hence the name).
This email makes its customers imagine a new type of product they could be revealing, and when I clicked, I was surprised to see all new items like towels, bedsheets and more.
Newsletter Subject Lines
Newsletter subject lines must work harder to get the recipient’s attention because they allude to information only. In contrast, a subject line offering a discount will automatically make the recipient want to click.
Newsletter subject lines must hook the reader and get them to click. The examples below do an excellent job at it.
29. “China Falls, Sleepy Unicorns, And The Deals Aren’t Bigger In Texas”
Sender: Crunchbase
The Crunchbase Insights email has an interesting way of wrapping details about all the stories it will present you in one subject line. This is eye-catching because it seems like an odd mashup of words, but gets to the point about three complicated stories at the same time.
When it comes to email, Crunchbase is known for its longer, text-based emails. They all read like a more conversational letter to the email recipient and casually discuss and hyperlink Crunchbase’s top stories. While the subject lines feel interesting and eye-catching, the emails often report deeper business news that cut right to the chase.
This subject line shows how you can be punchy, but also fun and creative when trying to pull in your audience.
30. “Watch Out for This Amazon Phishing Scam.”
Sender: WIRED
In this subject line, WIRED includes Amazon, a large company name. Including the name of a big brand can be a great way to boost open rates because people who enjoy or use products from big brands might click into a subject line that discusses them.
Additionally, when a brand name is combined with negative words like “phishing” or “scam,” people might open the email much more urgently so they can learn how to avoid running into the issue being discussed.
WIRED also lists the story last in its newsletter. This is an interesting way to get your readers to scroll through the entire email and see the other stories before they get to the story that led them to click into it.
31. “Buffer has been hacked — here is what’s going on”
Sender: Buffer
Next is a subject line from Buffer. A few years ago, Buffer got hacked — every tech company’s worst nightmare. But Buffer handled it exceptionally well, especially on the email front.
What we admire about the subject line is that it’s concise and direct. In a crisis, it’s better to steer clear of puns, snarky comments, and emojis. People want to see that you’re taking the situation seriously and be reassured that the world isn’t ending.
Because of the way the subject line is worded and formatted, you feel like Buffer is calm and collected about the issue, and is considering your personal safety. That’s pretty hard to do in just a few words.
32. “Google sees smartphone heroics in Oreo. It’s The Daily Crunch.”
Sender: TechCrunch
If you’re subscribed to a newsletter from a publication like TechCrunch, chances are, you signed up because you’re either interested in or want to learn more about technology. To reflect that, the media outlet crafts its daily email roundups (“The Daily Crunch”) with a subject line that reflects one of the latest, most compelling news items in the industry.
Here’s the thing: Staying on the cutting edge is hard, especially with something that evolves as quickly as technology. So, by writing email subject lines that reflect something recent and relevant, TechCrunch is signaling to email recipients that opening the message will help them stay informed and up-to-date on the latest industry news.
Think about the things that your audience struggles to keep up with — then, craft an email roundup and matching subject line that reflects the latest news in that category.
33. “Black Friday shoppers are the worst customers”
Sender: LinkedIn
This subject line is likely the boldest of the Black Friday emails you’d see in your inbox in the days before Thanksgiving. Yes, it’s a bit judgmental, but it actually came in a LinkedIn Pulse newsletter, promoting an article one of its users wrote on the topic of holiday marketing.
And there’s no doubt the title resonates with how some people feel during the most hectic holiday shopping day of the year.
LinkedIn has nothing to sell on Black Friday, so the subject line above does little harm to its business. Nonetheless, commenting on a popular cultural observation can show your confidence and help you relate to your community.
34. “New recipe alert 🚨”
Sender: Hello Fresh
While Hello Fresh is a food service that delivers meal packages to its customers, it also provides customers with home kitchen tips and tricks in email newsletters. These extra resources encourage home cooks to try new things, and being offered new recipe ideas is an exciting opportunity.
Using an emoji here is simple and draws the customer’s attention, while the offer itself can only be viewed in full when clicked — an easy way to draw in more aspiring home cooks.
35. “Tips to increase remote collaboration”
Sender: Asana
This simple subject line from Asana, a project management platform, gets straight to the point: If you open the email, you’ll find remote work tips and beyond. The subject line also effectively capitalizes on an increasingly common trend that rose during and after the COVID-19 pandemic. Its simplicity and trendiness ensure that you’ll want to open the email.
And chances are that if you’re using Asana, you’re likely using it to collaborate with colleagues whom you might not see every day, even if you’re not fully remote. Asana effectively appeals to a wide range of potential users and buyers with this subject line.
36. “I got Botox — & THIS is what it looked like”
Sender: Refinery29
Okay, so maybe your business doesn’t involve Botox. But still — are you intrigued? I am, and despite my better judgment, I clicked.
That’s the power of leading your emails with a story: It sparks curiosity, which works in two ways. There are times when our natural curiosity can pique our interest without context, such as the example above. But in this case, the subject line implies that there’s an intriguing story ahead. Why the heck did this person get Botox? And what did it look like? As the saying goes, “Inquiring minds want to know.”
Think of the stories behind your industry, then find ways to include them in email newsletters and frame them within the subject line in a way that piques your recipients’ collective curiosity.
37. “Improve Your Website from Concept to Code 💻”
Sender: Namecheap
Want people to open your newsletter? Tell them how they’ll benefit straight away like in this newsletter subject line by Namecheap. It used this subject line for Inspire, its monthly newsletter, and like in the WIRED example, it left the subject line story last so users would scroll through the entire email.
Like many examples on this list, it uses an emoji to draw the eye and keeps the tone of the conversation more casual and fun. In contrast, the subject line “Improve Your Website from Concept to Code” feels much more wooden and unfriendly.
38. “The best options for grocery delivery”
Sender: Wirecutter
Simple, right? But effective. This newsletter’s subject line from Wirecutter gets straight to the point and solves one of the biggest challenges we faced during the pandemic: How to get groceries while social distancing. If you’d never used grocery delivery services up until that point, you’d likely be at a loss for what services to use.
Wirecutter realizes that and immediately invites you to open the email with a simple and actionable subject like.
39. “Mark your calendar for these key dates!”
Sender: Omaze
Omaze is known for raising money for charities across the globe in the form of raffling once-in-a-lifetime opportunities with each donation. Contributors love to learn more about the charities at hand, and the sweet prizes they could win along with them on a monthly basis.
By announcing its upcoming opportunities, it can help people choose which causes they’ll want to give toward, and be excited to contribute when the time comes.
40. “‘I didn’t realize architecture was so dangerous’”
Sender: Dezeen
Dezeen is an architecture and design publication whose newsletter subject lines always feature a comment from a user. Only one comment is chosen every week.
This approach is brilliant for various reasons: 1) It makes you wonder why the user made that comment and will make you click through. 2) It makes you want to comment on the publication’s posts to potentially get featured. And 3) It takes the work out of writing a subject line. Indeed, Dezeen doesn’t have to write a subject line at all, because its readers do it for them.
Here are a few comments that have been featured of late:
- “Absolute garbage”
- “The cardboard box aesthetic”
- “Meet The Flintstones”
- “Does it come with a smoke machine?”
If you have a publication that’s often commented upon, consider using one of the comments as your subject line.
HubSpot Email Marketers’ Favorite Subject Lines
Above are some of the best subject lines we’ve gathered, but we asked both former and current marketers on our team to give some additional favorites and what makes them so good:
41. “Show them what you’re made of”
Sender: Canva
“Using empowering, positive, and defiant language to leverage the use of Canva tools — love it.”
— Lucy Reddan
42. “Drooling over email designs 🤤”
Sender: Really Good Emails
“Emojis always catch my eye amongst the 100+ emails I receive daily. As an email geek myself, this subject line matched my interests and piqued my curiosity.”
— Ashley Riordan
43. “Can you help me name this dance, [First Name]?”
Sender: Marie Forleo
“It’s personalized and piques my interest because A) I’m being asked for input and B) I want to be in the know about this mysterious dance (#fomo).”
— Christina Perricone
44. “Who you gonna call?”
“If you can make a pun, include a social reference, or even just a familiar phrase, it’ll catch people’s attention.”
— Clint Fontanella
45. “Shoes You Can Wear All Damn Day”
Sender: Everlane
“Swearing is controversial in email marketing, but I think it worked really well in this email from Everlane. Not only was it a clever and concise way to introduce their new line of footwear called ‘The Day Collection,’ but it also aligned with the brand voice they use in other emails and across their website.”
— Anna Fitzgerald
46. “You were on point last week 🎯”
Sender: Grammarly
“Grammarly is so good about rewarding you and making you feel good about your writing.”
— Jordan Pritikin
47. “Hmm…No writing activity last week?”
Sender: Grammarly
“If or when you turn their plugin off, Grammarly’s retention strategy is great. They reach out with subject lines like these that immediately drive me to click through and turn their plugin back on. Very well done.”
— Jordan Pritikin
48. “‘Not intended for swimming’”
Sender: Dezeen
“I’m a sucker for architecture, and Dezeen’s weekly newsletter tells me the top new projects that come up, as well as their reader’s responses to them. My question is: What’s not intended for swimming? And if it’s not intended for swimming, why did the architect build it? Boom, you’ve got my interest. And my click.”
— Ivelisse Rodriguez
49. “Our #1 most asked question…”
Sender: Supergoop
“What an easy way to get me to click — by trailing off and leaving the rest of the content in the email. Nicely done, Supergoop.”
— Ivelisse Rodriguez
50. “[First Name]! You’re One of HubSpot’s Top Blog Readers 🎉”
Sender: HubSpot
“No one actually likes taking feedback surveys. Not unless you earn money, and not many of them offer that. When I received the above email from our very own HubSpot blog, I clicked straight through, and voila! There it was: A feedback request. Turns out, flattery does work.”
— Ivelisse Rodriguez
The Best Email Subject Lines are Simple and On-Brand
When writing subject lines for your emails, keep it engaging, simple, and on-brand. Don’t forget to appeal to the emotions and needs of your target buyers, and most importantly, have fun — include emojis, puns, or references to pop culture. Your emails will get opened, guaranteed.
