Crafting the best email subject lines for sales doesn’t have to be a mysterious or challenging task. You simply have to understand the importance of this little line of text.
If your subject line doesn’t compel people to open your email, it doesn’t matter how good your copy or offer is (which is why it’s also important to learn how to write headlines).
So, let’s make your subject line just as good, if not better, than the rest of your persuasive writing.
While there is no definitive right or wrong way to write an email subject line, there are some tips you can use to boost your current open rates.
Here are 5 critical steps:
A study by Backlinko showed that the best email subject lines for sales are between 36 and 50 characters. In fact, this length outperformed short subject lines (1-15 characters) by 32.7%.
However, watch out for subject lines more than 70 characters, as open rates begin to diminish above that length.
If your subject line is too short, your audience likely won’t open the email because it’s hard to be specific in under 15 characters. When you write email subject lines for sales, you can’t afford to be vague.
For example, imagine receiving these subject lines in your inbox:
Those brief descriptions don’t give you a compelling reason to click, so they likely will perform poorly. On the other hand, short subject lines can be too specific and reveal too much too fast.
For example, you probably wouldn’t open these emails because they’re clearly trying to sell something:
However, these longer subject lines with descriptive language aren’t a dead giveaway that you’re going to sell something:
The only exception for writing shorter and somewhat vague subject lines is if your audience is already actively engaged with you.
For example, these three email subject lines, written by copywriter Justin Goff, work well because he has a small yet highly active email list:
Therefore, because the list is already actively engaged and invested in his content, short subject lines can be effective.
Good email subject lines for sales use proper etiquette, which is particularly important when sending cold pitches.
Therefore, avoid writing in all caps and don’t add too many exclamation points.
The only scenario where all caps might be appropriate is if you use them to emphasise a deadline.
For example, this is the last email in Ramit Sethi’s sequence to sell his course on finding a dream job.
Emojis are also becoming increasingly popular in the email marketing space, though they also require appropriate etiquette.
Search Engine Journal published a report after A/B testing emojis in their email subject lines, and it showed that seven out of ten campaigns with emojis received more abuse reports.
This can be devastating for deliverability, so be sure to keep an eye on that metric if you choose to use emojis.
In addition, the open rates for subject lines with emojis were actually lower than those without emojis.
Avoid making exaggerated statements unless you can truly justify them.
For example, if you choose to use any of these subject lines, your email must justify the claims:
A $25,000 bonus gift should be more than a free ebook and a coaching session. Similarly, if you have a million-dollar lesson, you should have a case study to go with it to show that your tip really did provide a million-dollar increase to the offer.
Nonetheless, case studies and data stories are a great way to hook people. In addition, each of the emails that followed these subject lines were able to justify the value. Incorporate your own versions of them in your email efforts, but don’t exaggerate any claims.
You can always improve your email subject lines, so continuously test them — a 1% increase in open rates can drastically improve email performance.
As you begin testing, change just one variable at a time to know which one was successful.
For example, a good test of two different subject lines might look like this:
How I Increased Conversions By 60%
How You Can Increase Conversions By 60%
Virtually all email marketing services now offer A/B testing tools. If you don’t want to pay for a service, Mailchimp allows you to have a free account for a limited number of subscribers, so you can start testing today.
Serving relevant content to your audience is essential to running a successful email marketing campaign. Therefore, in order to write better content that covers the right pain points, leverage email segmentation.
Email segmentation allows you to send specific content to specific prospects based on actions they have taken from previous emails and on your website. This is invaluable, as each person coming to your website has different needs.
For example, if you sell an SEO course, you may find that some of your buyers are new to SEO, whereas others might be agency owners looking for training material.
In this case, even though both parties are looking at the same course, their needs are very different, and they would respond better to two different pitches.
Those who are new to SEO would likely respond better to messaging that covers how a student went from an SEO newbie to making a living online, ideally six figures per year.
However, the CEO would likely prefer to see a case study showing how the course enabled a newbie SEO to double traffic/conversions in a matter of months and how it impacted business growth.
You can also segment your audience by gender, age, geography, and actions they’ve taken.
Research from Campaign Monitor also showed that segmentation is incredibly effective and can increase revenue by up to 760%.
Now that you have some basic guidelines for writing email subject lines for sales, here are some templates you can use to craft your own.
I swiped all of these examples from world-class copywriters like Ramit Sethi, Justin Goff, Larry Kim, and others, so they’ve been proven by the best of the best.
Enjoy!
Curiosity is an incredibly powerful tool to increase your open rates.
While vague subject lines will decrease your open rates, creating a story and leaving out a key piece of information will make your open rates skyrocket.
Notice that in each example, the copy builds drama (prints money, shed tears of joy) and omits one key part (THIS, 8-letter word, email secret).
If you need more inspiration, check out BuzzFeed titles. They have cracked the code to writing compelling headlines and you can use many of them as email templates.
When writing these headlines, it’s important to remember that while clickbait may be effective at generating open rates, it won’t drive sales if you don’t deliver. Therefore, be sure to always deliver on what you say you’ll do.
While curiosity often resonates better with prospects that respond emotionally, data is a great way to appeal to prospects that respond to logical pitches, so it should be a staple in every nurture sequence.
A study by CoSchedule of 155 million emails also showed that subject lines that included numbers experienced a 206% higher clickthrough rate than email subject lines without numbers.
So, here are some great data-driven email subject lines:
If you’re creating a nurture sequence, storyselling is a great way to get people hooked on your brand. In addition, your prospects won’t forget you as storytelling is 22 times more memorable for your reader.
Therefore, give the audience a teaser of the story in your subject line:
Offering a solution to avoid pain or avoid missing out is one of the most effective and fundamental copywriting tactics.
For example, the idea of losing a home triggers much stronger emotions than the idea of purchasing a home.
Therefore, by writing a subject line that focuses on pain-point avoidance, you can tap into heightened emotions and make your copy much more compelling (assuming that you have a great solution for their pain).
Here are some examples that focus on pain avoidance to help dramatically increase your open rates:
Perhaps the most important part about writing pain-avoidance subject lines is that you must know your audience on a personal level.
You should not only understand what they want, but also why they want it.
For example, if you sell a weight-loss product, your clients may not care about what the scale says. Instead, they may want to lose weight to confidently go to the beach with their families. That’s the real benefit.
While avoidance is a great way to grab your audience’s attention, you can also use the pain-point solution approach.
Therefore, rather than stimulating fear, the pain-solution approach is designed to stimulate pleasure. These solutions should include words like “easy,” “simple,” and “quick,” as they are taking the prospect away from pain.
Here are some of the best pain-solution subject lines:
Mentioning an influencer is a great way to increase open rates. It shows the prospect that you have similar idols and makes you appear more familiar.
For example, if you’re a basketball fan and someone sends you an email mentioning Michael Jordan, you’ll probably be more inclined to open that one in an inbox full of generic messages.
But if you mention an influencer, be sure it’s someone in your space rather than just a generic celebrity.
Here are some classy ways to mention an influencer without name dropping obnoxiously.
About 80% of customers are more likely to purchase from a brand that serves them personalized offers, so it’s no surprise that personalizing your email subject lines will help increase open rates as well as other key metrics.
These personalisation templates (particularly the first two below, which demonstrate a mutual connection) should be your go-to subjects for cold emails.
For nurture sequences, personalize your messages with a specific field such as the prospect’s name or company, as studies show that this can increase open rates by up to 50% across various industries.
You can also personalise the subject line based on an action the prospect took on your website (see Step #5 above about segmentation).
Science has proven that people love to talk about themselves. Research by Scientific American shows that talking about yourself lights up the same areas of the brain as eating good food or even taking drugs.
Therefore, centering the conversation around your reader rather than yourself can help you build relationships with them and keep them more engaged.
So, start by asking them a question about themselves in your subject line.
Here are a few good templates:
One of the best ways to stimulate sales from your emails is by creating urgency in your subject lines.
A 2018 study also proved the power of urgency when subjects consistently chose to perform unimportant tasks with an illusion of expiration over more important tasks.
While too much urgency too early in the sale may seem spammy or even turn people off, it’s an effective way to finish a nurture sequence and encourage people to take action.
If you’ve followed an expert for some time and the subject line goes against everything they have ever said, you’re probably enticed to click to see more.
This is the same tactic that television producers and magazine editors use to grab people’s attention.
Here are a few examples:
Obviously, most of these subject lines are ultimately addressing a problem within a certain industry and then explaining how your product/service fixes it.
Remember, your subject line will have a huge impact on your email marketing success. Take a few minutes to try out one of these templates and create a stellar subject line.
If you don’t hear back from a prospect, be sure to send a follow-up email and experiment with logical versus emotional sequences.
