In any relationship, your opening line sets the tone for what’s to follow and emails are no different. Your subject line communicates your email’s value to the recipient and encourages them to read further and, potentially, to engage with your brand on a deeper level by responding to your call to action (CTA).
A poor subject line is more than just bad: It can contribute to your email being marked as spam, dinging your reputation with your customer and search engines. In fact, 69% of email recipients report email as spam based solely on the subject line.
Even if your subscribers don’t report an email as spam, people typically look to the subject line to determine whether or not to open the email at all, so it needs to be as inviting as possible.
Clever, attention-getting email subject lines have the effect of increasing engagement and keeping your emails where they belong, in the inboxes of your prospects. That’s why it’s important to focus on your subject lines as an important part of your email marketing campaigns instead of leaving them as a last minute item to be completed right before you hit send.
How to write email subject lines that get results
Before we look at some specific examples of great email subject lines, let’s review what goes into making a subject line that resonates with the recipient.
To stay on target, you must:
1. Get the length right
You’ll need to do some testing to determine the optimal length for your customer base, but guidelines show that the sweet spot is a subject line that’s between 6 and 10 words in length.
A few more words or a few less doesn’t won’t adversely affect your results too much, but too many words (over 20) or no words at all will cause a problem.
2. Exclude the word “newsletter”
Do not, under any circumstances, use the word “newsletter” in the subject line of your email newsletter. Statistics show that email open rates go down by almost 19% when this word appears in the subject line.
That’s typically because people think of traditional newsletters as boring rather than full of valuable content, as yours will be.
3. Use A/B testing
One great way to make sure the subject line you craft is a winner is to conduct A/B testing over a few variations of subject lines. You can test word length, humorous tone versus something more to the point, word choice, or any other number of factors.
Once you’ve seen what type of subject line your audience likes and responds to most, you’ll be on your way to the best opens and engagement you’ve seen from an email marketing campaign yet.
4. Avoid spammy words, special characters, and SHOUTING
You want to keep your sender reputation pristine, and that means staying out of the spam folder. Nothing says “spam” to email recipients and internet service providers more than special characters (#%*@) and messages in ALL CAPS.
Some commonly used spam words include:
- Apply now
- Auto email removal
- Cash bonus
- Compare rates
- Double your income
- Earn $
- Earn extra cash
- Eliminate debt
- Explode your business
- Extra income
- F r e e
- Fast cash
Avoid the most common spam words and you’ll keep your subject lines out of trouble and your email out of the spam folder.
5. Consider all the options
There are many ways to approach email subject lines, from short and sweet, to personal, to keyword-specific, and more. Determine which of the many choices most closely fits your business’ personality and your audience’s preferences and then craft away.
Some typical types of subject lines include:
- Trending topic
- Short and sweet
- Sneak peek

Now that we’ve walked through the basics and given you plenty of references to whip up subject lines of your own, let’s take a closer look at what other companies have done with their subject lines to make their email marketing newsletters an inbox success.
1. Make them timely
Giving subscribers information they need when they need it helps boost open rates and email marketing success, as these subject lines show.
These four newsletter subject lines prove that timeliness is important when bringing information to subscribers. None of these subject lines is over-the-top clever, but nonetheless, they all performed well because the recipients wanted to receive the information offered.
2. Make them specific
Sharing location-specific information tells your subscribers you’re paying attention to them.
Most people have an innate curiosity about events in their local area, so using email subject lines like these can garner more clicks.
3. Use your numbers
Sometimes numbers speak louder than words because they make information quick and easy to digest.
Take a look at this example:
Not only does that subject line offer a clear benefit to the recipient, but it also has an actual person sending it. Having a person’s name in the sender field rather than the email looking like it came from an impersonal company or batch name increases the chances your newsletter will be opened and read.
4. Use targeted subject lines for segmented audiences
Segmented email campaigns achieve 760% more revenue than those that aren’t segmented.
You can break your audience into groups based on any number of factors, including:
- Geographical location
- Buying habits
Of course, you can use your email marketing to accomplish this task and then craft laser-focused email subject lines to wow your segmented groups.

Who doesn’t love a surprise? One great way to increase your newsletter open rate is to hint at a surprise inside.
You can use your subject line as a teaser:
Or, you can give a bigger hint, like letting subscribers know what kind of content they’re going to receive in your newsletter:
Giving your audience little treats like 3D content, infographics, guides, and floor plans make opening up your newsletter like opening a gift, a great way to increase your value in their eyes.
7. And finally, FOMO
FOMO, or Fear of Missing Out, is a great way to get subscribers invested in opening your email newsletter.
The more urgency you can deliver with your subject line, the more likely subscribers will be to want to see what your brand has in store for them.
Just be sure to deliver what your tagline promises: Opening an urgent email to discover there’s no real urgency will backfire on your marketing campaign and leave your audience cold.
Email newsletters are a great way to develop trust and confidence in your brand. Giving your customers information they need and want will help position your business as the go-to for value, whether that value is in the form of content, products, or services.
To get to that point in your relationship with subscribers, however, you need to get your content in front of your subscribers. That means getting it past the quick inbox skim that most people do when managing their daily overload of emails.
While writing a basic subject line can be relatively easy, crafting one that amps up the opens and gets your material read again and again is a bit trickier.
We’ve given you a whole batch of high-performing, high-quality email subject lines that can serve as inspiration for your next email marketing campaign to help your email newsletter find pride of place as an inbox regular.
