The Best Subject Lines For Email Marketing Examples

If you’ve ever received an email, you’re likely familiar with the subject line. The subject line is what shows up in your inbox and tells you what the content of the message is going to be about. All else being equal, a good subject line can help boost open rates and engagement with your emails. A poorly constructed or boring subject line will likely get ignored by recipients.

The goal of this article is to provide examples of different types of email marketing subject lines that work well for various industries (and even specific companies). We’ll also give some advice on how to create your own effective subject lines so that you can improve upon your existing campaign results!

1. Make your subject line specific

The first thing to remember when writing an email subject line is that it needs to be specific.

  • The reader should be able to tell what the email is about, without having to open it up.
  • Avoid generic and vague subject lines like “Update” or “Hi.” Instead, try something like: “Your survey results are in!” or “New product launch! Get 10% off.”
  • Also make sure you’re using the right tone for your audience. If you’re targeting people who are excited about technology and social media, a jokey approach might be best; but if your audience tends towards older folks who aren’t as familiar with these newfangled things, then maybe save the jokes for later—or at least tone them down a bit until everyone gets comfortable around each other’s communication style.

2. Keep it short

  • You may have heard that less is more when it comes to subject lines. And while that’s not always true, short subject lines are generally easier for readers to digest than longer ones.
  • Short subject lines are also more likely to be read and opened by subscribers who already know what they’re signing up for—and this group makes up a majority of your list! So if you want people to take action, don’t make them work too hard at reading your message.
  • Mobile devices are everywhere these days—and they tend to have smaller screens than laptops or desktop computers do (which means you’ll need shorter text). Plus, mobile users tend not only use their phones but also scroll through their inboxes quickly—so anything longer than five words might get skipped before being read in full!

3. Personalize the subject line

Personalization is the key to effective email marketing. There are plenty of ways to take your subject lines from great to amazing by personalizing them, including:

  • Segmenting your list by demographic data (age, gender, location) and creating a unique campaign for each segment
  • Merging tags into your subject line so it will be personalized based on who it’s going out to (e.g., using their name or company name)
  • Using purchase history and interests to create a more tailored message

4. Use simple words in the subject line

You can use simple words in the subject line. Use short words, not long ones. Make sure they’re easy to read and understand, in a way that will catch your reader’s eye quickly. Avoid jargon or technical terminology that might be unfamiliar to the average person on your list—you don’t want them to have to look up what “jargon” means! Also avoid abbreviations, acronyms, slang, and complex syntax (like run-on sentences).

5. Use a limited number of special characters

If you want your email to reach the inbox, you will need to follow this rule. Special characters like @#$%^&*()?+~`|, and many more can be problematic for some email clients.

Avoid using special character unless they are relevant to the subject line (e.g., birthday party invitation). If you have no choice but to use these characters in your message, then make sure that they are not going to create any confusion among users and make them think twice before clicking on it or worse still delete it without even opening it!

6. Create a subject line that matches the content of the email body

Don’t be surprised by this one. The content of your email body needs to match the subject line.

Your reader will immediately judge your email based on its title, so make sure it’s descriptive enough that they can quickly understand what they are about to read. If you have a difficult time coming up with a catchy title for the body or have something else in mind, then don’t worry too much about it—as long as it gets their attention and makes them want to keep reading!

Here are some tips for creating subject lines that match their corresponding body copy:

  • Make sure both pieces of writing use the same tone. For example, if you’re writing an optimistic email with an amusing subject line (e.g., “Do you like jokes?”), then make sure your body copy also sounds relaxed and funny. If not, people may get confused and feel like they’re missing something important from their inboxes because of how different everything seems compared to what they were expecting based on just reading one part at a time without context from either place first hand yet alone both simultaneously together which would require re-reading each section separately anyways so why bother? It just makes sense.”

7. Include numbers in your email subject lines to increase open rates

Numbers are a great way to grab attention and give readers a sense of what the email will be about. For example, if you’re writing an email with the subject line: “5 ways to improve your marketing,” readers will expect the content to be five tips on how they can best market themselves.

Because numbers help create a sense of urgency, they also increase open rates by increasing the chances that your reader will see them as important enough to read right away.

Your email’s success depends on the subject line.

Your email’s success depends on the subject line.

The first thing your reader sees, it must catch their attention and compel them to open it. A good subject line should be short and to the point, include a call to action, inform the reader who sent it (either by name or brand), and if possible, remind them of something that was discussed in an earlier email.


At this point, it may seem that email subject lines are a bit of an art and a bit of a science. The truth is, the best way to understand what makes a good subject line for emails is by testing different methods with your own audience and tracking their results. As you test various messages and strategies, keep an eye on metrics like open rate and click-through rate—these will help you gauge which ones worked better than others. And once you’ve done that? Then it’s time to do it all over again. An email’s subject line is clearly a significant component of the overall message. And, as you’ve seen here, there are many different ways of writing a subject line to reflect your particular goals. Ultimately, though, it’s probably best to be creative and straightforward at the same time. Having a creative title won’t hurt your message’s chances—but if it’s too confusing or hard to read, you’ve already lost some potential readers and contacts out the door. Thus, having a clear and concise subject line that reflects the content of your email is likely the best practice for getting the most open rates possible.
