Do you want people to open, read, and click on your emails? The subject line is where it all begins. According to HubSpot, 47% of marketers claim that they test alternative subject lines to improve the performance of their emails. This makes it critical to write intriguing subject lines that entice visitors to click through. While the best email subject lines appear to be a minor aspect of your message, they are one of your readers’ initial impressions. They’re also a marketer’s ticket to making their message stand out in a congested inbox. After all, people do evaluate emails by their subject lines. 

An effective email begins with a subject line that captures readers’ attention. People are more likely to read your material if the subject line is personal and concise. Whatever method you use, keep your audience in mind and experiment with different terms and phrases to determine what they like. In this post, you will discover how to write compelling subject lines and measure their effectiveness.

Key Email Subject Line Tips

Some subject lines have been proven to be more effective than others. Here are a few email subject line tips ideas to get you started. 

1. Personalize the experience

Personalize your subject lines with each recipient’s name or location by using merge tags. Personalization has been demonstrated to enhance open rates, and you can pair it with specific automation strategies, such as birthday wishes or post-purchase surveys. 

2. Be detailed with your writing

Sometimes it’s best to be straightforward and detailed rather than fashionable. Seasonal phrases such as “Fall into savings” or “Sizzling summer discounts” are attractive, yet they lack a clear call to action (CTA). Instead, strive to highlight certain bargains or describe the benefits of your promotions.

3. Keep it brief

Shorter subject lines are frequently better for many receivers, especially those who read your emails on mobile devices. We recommend that you stick to a maximum of nine words or 60 characters.


4. Use as little punctuation as possible

You should not use more than three punctuation marks in a subject line. Too many punctuation marks, especially if you use a lot of special characters, might make your email appear spammy.

5. Emojis should be used with caution

When using emojis, there are a few things to keep in mind. You should only use one emoji at a time. Emojis should be used to augment rather than replace words to ensure that your core message is conveyed. Emojis appear differently on different operating systems; therefore, it’s crucial to send a test email first.

9 Top Email Subject Line Examples

A good email subject line is concise, clear, and to-the-point. It grabs and retains the reader’s attention and gives them a taste of what your email is about. Here are some of the best email subject lines to incorporate in your emails. 

1. To-the-point subject lines

There’s a lot to be said about simplicity; people want you to be precise and simple in your subject lines, because time is a valuable commodity. Short, detailed subject lines outperform corny ones. Some may scoff at the suggestion that comedy and inventiveness should be ignored when crafting email subject lines, especially when many marketing gurus disagree. It’s worth mentioning that this concise approach works best with notification emails, because the recipient already has a connection to the material you’re sending.

Keep in mind that people check their inboxes rapidly, so make your subject line as clear and brief as possible. Unless you’re looking for an elusive subject to intrigue your recipients with, it’s typically best to be brief than to throw around flowery words. When writing a subject line, consider how it will help your receivers understand the email better. For example, instead of saying, “How to look beautiful in our kimono”, you can write, “3 ways to style our kimono”. 


2. Controversial or shocking subject lines

Controversy tends to sell and attract a lot of attention. It’s hard to simply skim through subject lines that may scandalize readers. However, you must be careful when using shock or controversy in your subject lines. By using such subject lines generously, you could gain more open rates, but at the risk of losing clients. This method necessitates trust in your knowledge of your audience’s preferences and requirements. It’s a bit of a tightrope, but the payoff may be great. 

3. Urgency-inducing subject lines

Creating a sense of urgency is a great tool for compelling users to act. When you write a subject line that screams urgency, users browsing their inboxes may stop to open your email and check if there are any limited-period offers worth clicking on. You can also apply this strategy through a series of emails, but make sure not to spam the reader. 

4. Use a familiar sender name

Make your sender name as human-like as possible. When people check their inboxes, [email protected] is both welcoming and unintimidating. Even though the email is officially coming from the organization, use your own name as the sender’s address if you’ve previously met your recipients. The best feeling you can give your consumers is that they’re dealing with you, not the company as a whole.

5. Get the timing right

Sending an email at the right time and with the right subject line may significantly improve open and click-through rates. Is there a good email subject line example for this? Yes. If you have a bar and it’s International Women’s Day in a week, you can shoot an email with a subject line carrying a ladies’ night offer. Another great example could be a subject line alerting the reader to the fact that their subscription to your service is about to expire. Sending an email at the accurate time—and including a CTA button—is an important email subject line tip. 

6. One-word subject lines

Using one-word subject lines is another great email subject line tip. With millions of emails vying for readers’ attention, how do you make sure yours stands out? By crafting a single-word subject line. It evokes curiosity in your readers, and makes them want to click on the preview text in order to see what awaits them. 


7. Subject lines with questions

Another way to stand out from the crowd is to use question marks. Exclamation marks are good, but they’re overused in subject lines, so they may not be particularly effective. You can instead play around with some colourful symbols or question marks to catch people’s attention. In contrast to a typical statement, asking your readers a question hooks them right away. Questions start a conversation with users immediately, making your emails more likely to be opened. 

8. Subject lines with scarcity strategies

Almost all of us are governed by this profound fear of missing out (FOMO)—it used to be a survival instinct, but today, it’s simply another subject line trick to get us to buy something. Limited-period offers are one such example that perform well. To avoid “losing out,” people can do unimaginable things. If you use scarcity strategies or incorporate the FOMO element in your subject lines, you might be shocked at how your click rates shift. For some real subject line success, use numbers, scarcity, punctuation, and partial capitalization (the operative word being “partial”). 

9. Subject lines that evoke curiosity

Curiosity is one of the greatest tools to capture the interest as well as attention of the reader. Curiosity-inducing subject lines cause the reader to wonder what lies inside, thereby luring them into clicking through. However, even if the subject line is curious, make sure it aligns with the rest of the content. If it’s too secretive, it can be considered spammy. Some words that you can use for such subject lines include “secret”, “unbelievable”, “strange”, “unlock”, “little-known”, etc.

In other words, a subject line summarizes the contents of the email without giving too much away.
