Best practices for using emojis in email subject lines

November 18, 2023 | Jimit Mehta

Picture this: you're scrolling through your inbox, trying to decide which email to open first. You come across one with a subject line that catches your eye, and you click on it without a second thought. What made that subject line stand out? Chances are, it had an emoji in it. Emojis have become an integral part of our communication in the digital age, and they can be incredibly effective in email subject lines. But with great power comes great responsibility. How do you use emojis in email subject lines without coming across as unprofessional or cheesy? In this article, we'll go over the best practices for using emojis in email subject lines, so you can make the most of this powerful tool and engage your audience like never before.

Why use emojis in email subject lines?

When it comes to email marketing, the subject line is often the first (and sometimes only) impression you get to make on your audience. The goal is to catch their attention, pique their interest, and encourage them to open the email. And that's where emojis come in.

Emojis are a visual way to convey emotions, ideas, and information in a single character or small set of characters. They're eye-catching and attention-grabbing, making them a great addition to email subject lines. By using emojis in your email subject lines, you can:

  1. Stand out in a crowded inbox: Emojis can help your subject line stand out in a sea of plain text. They draw the eye and make your message more noticeable, increasing the chances that your email will be opened.

  2. Convey emotion and tone: Emojis can help you convey the tone and emotion of your message before the email is even opened. For example, a smiley face can indicate a friendly, casual tone, while a heart can convey warmth or appreciation.

  3. Convey information: Emojis can also be used to convey information in a concise way. For example, a calendar emoji can indicate an upcoming event, while a shopping bag emoji can indicate a sale or promotion.

Overall, using emojis in email subject lines can help you connect with your audience on a more personal level and increase the chances of your emails being opened and read. However, it's important to use them strategically and in moderation, so as not to come across as unprofessional or spammy.

Which emojis work best in email subject lines?

Now that we know why emojis can be a great addition to email subject lines, the next question is which emojis work best. While the answer to this question can vary depending on your audience and the content of your email, there are some general guidelines to keep in mind.

First and foremost, it's important to choose emojis that are relevant to the content of your email. If you're promoting a sale, for example, a shopping bag or money bag emoji could work well. If you're sending a newsletter about food, a pizza or a cupcake emoji could be appropriate.

It's also a good idea to stick with universally recognized emojis. The basic smiley face, thumbs up, and heart emojis are universally understood and can be used in a variety of contexts. On the other hand, some emojis can have different meanings in different cultures, so it's important to be aware of any potential misinterpretations.

Another thing to consider is the size of the emoji. Some emojis, such as the dancing woman or the rocket, can be quite large and may take up too much space in the subject line. Stick with smaller, more subtle emojis to avoid overwhelming your subject line.

Finally, use emojis sparingly and strategically. A subject line that's filled with emojis can come across as unprofessional or spammy. One or two well-placed emojis can add some visual interest and help your email stand out, but don't overdo it.

In summary, when choosing which emojis to use in email subject lines, it's important to consider relevance, universality, size, and quantity. By following these guidelines, you can use emojis effectively to enhance the impact of your email marketing campaigns.

When should you avoid using emojis in email subject lines?

While emojis can be a great addition to email subject lines, there are certain situations in which it's best to avoid using them. Here are some examples:

  1. Formal or professional emails: If you're sending an email to a client, a business partner, or a potential employer, it's best to err on the side of caution and avoid using emojis in the subject line. Depending on the industry and the culture of the organization, emojis may be seen as unprofessional or inappropriate.

  2. Serious or sensitive topics: If your email is about a serious or sensitive topic, such as a job loss, a medical diagnosis, or a family emergency, using emojis can come across as insensitive or inappropriate. Stick with plain text to convey the gravity of the situation.

  3. Overly promotional or spammy emails: If your subject line is already filled with marketing language or exclamation points, adding emojis may make it seem even more spammy. Emojis should be used to enhance the meaning of the subject line, not replace it.

  4. Technical or scientific content: If your email is about a technical or scientific topic, emojis may be seen as unprofessional or juvenile. Stick with plain text to convey your expertise and professionalism.

  5. When unsure of your audience: If you're not sure how your audience will respond to emojis, it's better to err on the side of caution and avoid using them in the subject line. You can always test the waters with a small group of recipients before sending the email to your entire list.

In summary, while emojis can be a powerful tool in email subject lines, it's important to use them appropriately and strategically. When in doubt, it's best to stick with plain text and let the content of your email speak for itself.

How many emojis should you use in an email subject line?

When it comes to using emojis in email subject lines, the question of how many to use is an important one. While there's no hard and fast rule, there are some general guidelines to keep in mind.

First and foremost, it's important to use emojis sparingly. A subject line that's filled with emojis can come across as unprofessional or spammy. One or two well-placed emojis can add some visual interest and help your email stand out, but don't overdo it.

In some cases, using a single emoji can be just as effective as using multiple ones. For example, if you're promoting a sale, a simple money bag emoji could be enough to convey the message.

It's also important to consider the length of your subject line. If your subject line is already on the longer side, adding too many emojis can make it feel cluttered and overwhelming. Stick with one or two well-chosen emojis to keep your subject line concise and impactful.

Finally, consider your audience and the tone of your email. If your email is more lighthearted and casual, using more emojis may be appropriate. On the other hand, if your email is more formal or professional, one or two well-placed emojis may be more appropriate.

In summary, when it comes to using emojis in email subject lines, less is often more. By using them sparingly and strategically, you can enhance the impact of your subject line and increase the chances of your email being opened and read.

Using emojis to convey tone in email subject lines

One of the most powerful ways to use emojis in email subject lines is to convey tone. Emojis can help you express emotions and set the tone for your email, even before the recipient opens it. Here are some tips for using emojis to convey tone in email subject lines.

  1. Use emojis to express enthusiasm: If you're excited about something, using an exclamation point or a smiley face emoji can help convey that enthusiasm to the recipient. For example, a subject line that says "We're launching a new product line!" with a smiley face emoji can help convey the excitement of the announcement.

  2. Use emojis to express urgency: If your email requires immediate attention, using a clock or an alarm clock emoji can help convey the urgency of the message. For example, a subject line that says "Urgent: Meeting time changed ⏰" can help convey the importance of the message and the need for immediate action.

  3. Use emojis to express humor: If you're trying to inject some humor into your email, using a laughing face or a winking face emoji can help convey the tone. For example, a subject line that says "You won't believe what happened today 😉" can help convey the lighthearted nature of the message.

  4. Use emojis to express gratitude: If you want to thank someone, using a heart or a thumbs up emoji can help convey the sentiment. For example, a subject line that says "Thank you for your support ❤️" can help convey the gratitude and appreciation.

In summary, using emojis to convey tone in email subject lines can be a powerful way to set the stage for your email and enhance the emotional impact of your message. By choosing the right emojis and using them strategically, you can make your email more engaging and increase the chances of it being opened and read.

Making sure your emojis display correctly across different devices

When using emojis in email subject lines, it's important to make sure that they display correctly across different devices. The way an emoji looks on one device may be different from how it looks on another, which can lead to confusion or miscommunication.

To ensure that your emojis display correctly, it's important to choose emojis that are widely supported and avoid using less common or newer emojis that may not be supported on all devices. For example, using a heart or a smiley face emoji is a safer bet than using a more obscure or specialized emoji.

Another way to ensure that your emojis display correctly is to test your email across different devices and email clients before sending it. This can help you identify any issues with how your emojis are displaying and make any necessary adjustments.

Additionally, it's important to keep in mind that emojis can look different on different platforms, even if they're widely supported. For example, the same heart emoji may look slightly different on an iPhone than it does on an Android device. While this may be a minor difference, it's something to keep in mind when using emojis to avoid any confusion or misinterpretation.

In summary, making sure your emojis display correctly across different devices is an important consideration when using emojis in email subject lines. By choosing widely supported emojis, testing your email across different devices, and keeping in mind that emojis can look different on different platforms, you can ensure that your emojis are effective and enhance the impact of your subject line.

Examples of effective emoji use in email subject lines

Using emojis in email subject lines can be a great way to catch the recipient's attention and make your message stand out. Here are some examples of effective emoji use in email subject lines that you can use as inspiration:

  1. 🎉 Sale Alert: 20% off everything in store!This subject line uses the party popper emoji to convey excitement and draw attention to the sale. It's a great way to grab the recipient's attention and encourage them to open the email.

  2. 🌟 Your Favorite Products are Back in Stock!This subject line uses the star emoji to convey the importance of the message and make it stand out in the recipient's inbox. It's a great way to make the message seem more valuable and increase the chances of it being opened.

  3. 🤔 Can You Help Me With Something?This subject line uses the thinking face emoji to convey curiosity and encourage the recipient to open the email to find out what you need help with. It's a great way to make the message seem more personal and increase the chances of a response.

  4. 📈 Our Q1 Report is In – Check it Out!This subject line uses the chart increasing emoji to convey growth and success, making the message seem more positive and encouraging. It's a great way to catch the recipient's attention and encourage them to read the report.

  5. 🔥 Breaking News: Big Changes Coming!This subject line uses the fire emoji to convey urgency and make the message seem more important. It's a great way to draw attention to the message and increase the chances of it being opened.

In summary, using emojis in email subject lines can be a great way to make your message stand out and encourage the recipient to open the email. By using emojis strategically and creatively, you can enhance the impact of your subject line and increase the effectiveness of your email marketing efforts.

Experimenting with emojis in A/B testing to improve open rates

A/B testing is a powerful technique for optimizing email subject lines, and it can be particularly effective when it comes to using emojis. By testing different emoji choices and placement, you can determine what works best for your audience and improve your email open rates.

To get started with A/B testing, you'll need to create two different versions of your email subject line: one with an emoji and one without. You can then send these versions to two separate groups of subscribers, with everything else in the email staying the same.

Once you've sent out both versions, you can analyze the results to see which subject line performed better. If the subject line with the emoji had a higher open rate, it's a good indication that your audience responds well to that particular emoji and that you should continue using it in future emails. On the other hand, if the subject line without the emoji had a higher open rate, you may want to reconsider using emojis or experiment with different emoji choices to see if you can find one that resonates better with your audience.

It's important to note that A/B testing requires careful planning and execution to ensure accurate results. You should only test one variable at a time, such as the presence or absence of an emoji, to avoid confusing the results. You should also test your emails on a large enough sample size to ensure that the results are statistically significant.

In summary, A/B testing can be a powerful way to experiment with emojis in email subject lines and optimize your open rates. By testing different emoji choices and placement, you can learn what works best for your audience and create more effective email subject lines in the future.

Balancing professional communication with a touch of personality through emojis

In today's fast-paced digital world, it can be difficult to strike a balance between professional communication and adding a personal touch. While emojis may seem like a frivolous addition to your emails, they can actually be a useful tool for conveying tone and personality while still maintaining a professional image.

When used correctly, emojis can help you establish a more human connection with your audience and make your messages more memorable. For example, a smiley face can help convey a friendly tone, while a heart can show appreciation or gratitude.

However, it's important to use emojis in moderation and to choose them carefully. Overuse of emojis can make your message seem unprofessional or even childish. It's also important to be aware of cultural differences in the interpretation of emojis - what may be perfectly innocent in one culture may be seen as offensive or inappropriate in another.

To strike the right balance between professionalism and personality, consider your audience and the context of your message. If you're writing to a new client or a potential employer, it may be best to err on the side of caution and avoid using emojis altogether. On the other hand, if you're writing to a long-time customer or a colleague, a well-placed emoji can help convey a more friendly and approachable tone.

In summary, using emojis in email communication can be a great way to add a personal touch to your messages and establish a more human connection with your audience. However, it's important to use emojis thoughtfully and in moderation, and to be aware of cultural differences in their interpretation. By striking the right balance between professionalism and personality, you can make your emails more memorable and effective.

Avoiding cultural misinterpretations with the use of emojis in email subject lines

Emojis have become a ubiquitous part of online communication, but it's important to remember that not everyone interprets them the same way. What may be perfectly innocuous in one culture may be seen as offensive or inappropriate in another. To avoid cultural misinterpretations with the use of emojis in email subject lines, it's important to be aware of the potential pitfalls and choose your emojis carefully.

One way to avoid cultural misinterpretations is to stick to emojis that are universally recognized and have a clear meaning. For example, a smiley face or a heart is likely to be understood and appreciated across cultures. On the other hand, emojis that have a more specific cultural meaning, such as the "thumbs up" gesture, may not be universally understood and could be misinterpreted.

It's also important to be aware of any cultural or religious sensitivities that may exist. For example, some cultures may consider certain animals or symbols to be taboo, while others may have specific associations with certain colors or shapes. To avoid causing offense, it's important to do your research and choose emojis that are appropriate for your audience.

Another way to avoid cultural misinterpretations is to use emojis in moderation. Overuse of emojis can make your message seem unprofessional or even juvenile, and may lead to misinterpretations or misunderstandings.

In summary, while emojis can be a great way to add personality and warmth to your email subject lines, it's important to be aware of potential cultural misinterpretations. By choosing your emojis carefully and using them in moderation, you can ensure that your message is received positively and that you avoid causing offense or misunderstandings.

Over to you

In the fast-paced world of email communication, using emojis can be a great way to add a personal touch to your messages and improve your open rates. However, it's important to use emojis thoughtfully and in moderation, and to be aware of potential cultural misinterpretations.

When choosing which emojis to use, it's important to consider your audience and the context of your message. Stick to universally recognized emojis with clear meanings, and be aware of any cultural or religious sensitivities that may exist. Additionally, use emojis in moderation and avoid overuse, which can make your message seem unprofessional or juvenile.

Experimenting with emojis in A/B testing can help you identify which ones work best for your audience, while also conveying tone in your subject lines. By striking the right balance between professionalism and personality, you can make your emails more memorable and effective.

Overall, using emojis in email subject lines can be a valuable tool for establishing a more human connection with your audience. With a little thought and consideration, you can improve your open rates and make your messages stand out in a crowded inbox.
