Written by Jimit Mehta | Mar 5, 2023 8:00:00 AM

Email is one of the most effective communication channels in today's digital age. Whether you're sending a message to a friend or reaching out to a potential employer, the subject line is the first thing that recipients will see. A compelling subject line can make all the difference when it comes to getting your message noticed, opened, and read. In fact, according to a study by Convince & Convert, 35% of recipients decide whether to open an email based on the subject line alone. So, if you want your emails to stand out in a crowded inbox and capture your reader's attention, it's essential to craft subject lines that are both persuasive and memorable. In this article, we'll share some practical tips and best practices for writing subject lines that grab attention, entice readers, and compel action.

Keep it short and sweet

When it comes to writing email subject lines, brevity is key. People receive a large number of emails every day, and they often quickly scan through their inbox to decide which messages are worth their time. A long, wordy subject line can be overwhelming and unappealing to readers.

To grab your reader's attention and entice them to open your email, it's important to keep your subject line short and sweet. Ideally, your subject line should be around 5-10 words or 40-50 characters, so it's easy to read and understand at a glance.

Think about the main message or benefit that you want to convey in your email and try to capture it in a brief and compelling phrase. Avoid using filler words or unnecessary details that might dilute the impact of your message.

By keeping your subject line short and sweet, you increase the likelihood that your message will stand out and be opened. So, take a few moments to craft a concise and engaging subject line that captures your reader's attention and encourages them to read on.

Make it personalized

When it comes to email subject lines, personalization can go a long way in capturing your reader's attention and building a connection with them. Simply put, personalized subject lines are those that are tailored to the specific recipient, rather than being generic or generic-sounding.

Personalization can take many forms, such as using the recipient's name, referencing a recent interaction or purchase, or even acknowledging their interests or preferences. By showing that you understand and care about the recipient's needs, you can make your email subject line much more appealing and relevant to them.

Using the recipient's name in the subject line is a classic and effective way to personalize your message. Many email marketing tools now allow you to insert the recipient's name automatically, which can help you save time and boost your open rates.

You can also use other information, such as their location, job title, or industry, to make your subject line more personal and relevant. For example, if you're sending an email to a marketing manager, you might use a subject line like "5 Tips to Boost Your Marketing Strategy, Sarah!".

Personalization can be a powerful tool in making your emails stand out and resonate with your readers. So, take the time to research your recipients and craft subject lines that speak to their individual needs and interests.

Use actionable language

When crafting email subject lines, it's important to use actionable language that inspires the recipient to take action. An actionable subject line can create a sense of urgency and encourage the reader to open the email and engage with your message.

Actionable language refers to words or phrases that prompt the reader to do something, such as "register now", "don't miss out", or "download your free guide". These types of subject lines convey a clear benefit or value to the reader and give them a reason to open your email and take action.

Incorporating action-oriented words into your subject line can help you stand out in a crowded inbox and differentiate your message from other emails that may be more passive or generic. However, be careful not to use too much hype or false promises in your subject line, as this can lead to disappointed readers and low engagement rates.

To create a compelling subject line that uses actionable language, focus on the main benefit or value that you want to convey in your email and use action words that align with that message. Whether you're promoting a sale, inviting readers to an event, or sharing helpful tips, using actionable language can help you get your message across and drive results.

Use numbers or statistics

Numbers and statistics are a powerful tool when it comes to creating compelling email subject lines. Research has shown that including numbers in a subject line can increase open rates and make your message more appealing to readers.

Numbers and statistics help to add a sense of specificity and credibility to your subject line. For example, a subject line like "5 Ways to Save Money on Your Next Vacation" is more specific and actionable than a more generic subject line like "How to Save Money on Travel". The number "5" makes it clear that the email will provide a finite list of tips, and the reader can expect a focused and useful message.

Additionally, statistics or other figures can help to pique the reader's curiosity and motivate them to open the email. For example, a subject line like "90% of People are Making this Critical Mistake" can be more attention-grabbing than a subject line that doesn't include a statistic.

Using numbers and statistics in your email subject line can also help you to stand out from other messages in your reader's inbox. People receive a large number of emails every day, and subject lines that include numbers or statistics are more likely to capture their attention and motivate them to open your email.

However, be sure to use numbers or statistics that are relevant and meaningful to your readers. Avoid using numbers simply for the sake of using them, and always ensure that they support the main message or benefit of your email. By using numbers and statistics effectively in your subject lines, you can create more engaging and impactful messages that drive results.

Create a sense of urgency

Creating a sense of urgency in your email subject line is a powerful way to motivate your readers to take action. When people feel like they need to act quickly to avoid missing out on a valuable opportunity, they are more likely to open your email and engage with your message.

There are many ways to create a sense of urgency in your subject line. For example, you might use phrases like "limited time offer", "act now", or "don't miss out" to convey the urgency of your message. You could also use a deadline, such as "register by Friday" or "ends tonight", to add a sense of immediacy and encourage the reader to take action right away.

Creating a sense of urgency can be particularly effective when promoting time-sensitive offers or events. For example, a subject line like "Last chance to register for our exclusive webinar" can be more compelling than a more generic subject line.

However, it's important to strike a balance between urgency and pressure. You don't want to create a false sense of urgency or use manipulative tactics that might turn off your readers. Instead, focus on providing a clear and valuable benefit to the reader, and use urgency in a way that reinforces that benefit.

By creating a sense of urgency in your email subject line, you can increase the likelihood that your message will be opened and acted upon. Just be sure to use this tactic thoughtfully and strategically, and always prioritize providing real value to your readers.

Make it visually appealing

Making your email subject line visually appealing is an important aspect of creating a compelling message. When your subject line stands out visually, it's more likely to catch the reader's eye and motivate them to open your email.

One way to make your subject line visually appealing is to use design elements like emojis, symbols, or special characters. These can help to break up the text of your subject line and make it more eye-catching. For example, a subject line like "🎁 Don't Miss Our Holiday Sale - 50% Off Everything!" can be more visually appealing and engaging than a subject line without any design elements.

Another way to make your subject line visually appealing is to use formatting like bold or italicized text, capital letters, or line breaks. These can help to create emphasis and draw attention to key parts of your subject line.

It's important to keep in mind that different email clients and devices might display your subject line differently, so be sure to test your subject lines across multiple platforms to ensure they look the way you intend.

However, it's also important to not go overboard with design elements or formatting, as this can make your subject line look cluttered or unprofessional. Focus on using design elements and formatting in a way that enhances your message and makes it more visually appealing without detracting from its clarity or value.

By making your email subject line visually appealing, you can help it stand out in a crowded inbox and increase the likelihood that your message will be read and engaged with.

Avoid spam trigger words

Avoiding spam trigger words in your email subject line is essential to ensuring that your message reaches your readers' inboxes and doesn't get flagged as spam. Many email providers use automated filters to identify and block emails that include certain words or phrases that are commonly associated with spam or unsolicited messages.

To avoid triggering these filters, it's important to steer clear of common spam trigger words and phrases like "free", "win", "guaranteed", "limited time", and "act now". These words can raise red flags for email providers and cause your message to be filtered out of your readers' inboxes.

Additionally, using excessive punctuation or using all caps in your subject line can also trigger spam filters. It's best to keep your subject line concise and avoid using excessive punctuation or capitalization.

One way to avoid using spam trigger words in your subject line is to focus on providing a clear and valuable benefit to the reader. Rather than using hype or overly salesy language, focus on crafting a subject line that clearly conveys what your email is about and what the reader can expect to gain from reading it.

Another way to avoid triggering spam filters is to personalize your subject line and avoid using overly generic or spammy-sounding language. By tailoring your subject line to your specific audience and using language that sounds genuine and authentic, you can increase the likelihood that your message will be well-received and engaged with.

By avoiding spam trigger words and focusing on providing real value to your readers, you can create subject lines that are more likely to be delivered and opened, leading to higher engagement and better results for your email marketing efforts.

Be clear and specific

Being clear and specific in your email subject line is crucial for grabbing the reader's attention and motivating them to open your message. A subject line that is vague or unclear can be confusing or unappealing to the reader, making them less likely to engage with your message.

To be clear and specific in your subject line, it's important to use language that accurately conveys the content of your email. Avoid using generic or overly broad language that could apply to a wide range of messages, as this can make it difficult for the reader to understand what your email is about.

Instead, focus on using language that is specific to the topic of your email and provides a clear benefit to the reader. For example, a subject line like "5 Strategies for Boosting Your Productivity at Work" is much more specific and compelling than a subject line like "Tips for Success". The more specific you can be in your subject line, the more likely the reader is to understand what your email is about and engage with your message.

In addition to using specific language, it's also important to keep your subject line concise and to the point. Avoid using unnecessarily long or complex language, as this can make your subject line difficult to read and understand. Instead, focus on using simple, direct language that clearly communicates the benefit of your message.

By being clear and specific in your email subject line, you can grab the reader's attention and motivate them to engage with your message. This can lead to higher open rates, better engagement, and more successful email marketing campaigns overall.

Use humor or wit (carefully)

Using humor or wit in your email subject line can be a great way to grab the reader's attention and make your message stand out. A clever or witty subject line can pique the reader's curiosity and motivate them to open your message, increasing the likelihood that they will engage with your content.

However, it's important to use humor or wit carefully in your email subject line. A subject line that is too silly or frivolous can come across as unprofessional or inappropriate, which could turn off your readers or damage your brand image.

To use humor or wit effectively in your subject line, it's important to understand your audience and what types of humor or wit are likely to resonate with them. For example, a subject line that uses playful wordplay or pop culture references might be more effective for a younger or more casual audience, while a subject line that uses dry humor or irony might be better suited for a more professional or sophisticated audience.

It's also important to be careful not to offend or alienate your readers with your humor or wit. Avoid using humor that is overly sarcastic, critical, or potentially offensive, as this could damage your relationship with your readers and make them less likely to engage with your message.

Overall, using humor or wit in your email subject line can be an effective way to grab the reader's attention and make your message stand out. However, it's important to use humor or wit carefully, taking into account your audience and your brand image, to ensure that your message is well-received and engages your readers effectively.

Test and analyze your subject lines

Testing and analyzing your email subject lines is a crucial step in improving the effectiveness of your email marketing campaigns. By experimenting with different subject lines and analyzing the results, you can gain valuable insights into what types of subject lines are most effective in engaging your audience and motivating them to open and engage with your messages.

To test and analyze your subject lines, start by creating multiple variations of your subject line and sending each version to a small subset of your email list. Monitor the open rates and engagement rates for each version, and use this data to determine which subject lines are most effective in engaging your audience.

You can also use A/B testing to test different elements of your subject line, such as the length, the tone, or the use of specific keywords or phrases. By testing different variations of your subject line and analyzing the results, you can gain insights into what types of subject lines are most effective for your audience and adjust your email marketing strategy accordingly.

In addition to testing your subject lines, it's important to analyze your data to identify trends and patterns in your audience's behavior. Look for patterns in open rates, engagement rates, and click-through rates, and use this data to optimize your email marketing strategy over time.

By testing and analyzing your subject lines, you can gain valuable insights into what types of subject lines are most effective in engaging your audience and motivating them to open and engage with your messages. This can help you to optimize your email marketing strategy, improve your open rates and engagement rates, and drive better results from your email campaigns.
