Your Guide to Writing Compelling Subject Lines

Written By: Geoffery Blanc, General Manager at Cyberimpact

Do you feel like your emails aren’t getting the love (or open rates) that they deserve? It’s not you… It’s your subject line. A well-crafted subject line can make all the difference between getting your message opened or ignored.

A compelling subject line is essential for grabbing your audience's attention and enticing them to open your email. In this article, we’re going to explore the key elements of a compelling subject line, techniques for writing effective subject lines, and provide examples and case studies to help you improve your subject line game.

Key Elements of a Compelling Subject Line

A well-crafted subject line can do wonders for your campaign analytics and even help in enhancing your brand’s perception. On the other hand, poor subject lines can lead to low open rates, unengaged audiences, poor brand perception, and decreased conversions. By incorporating a few solid elements, you can ensure your emails get noticed, read, and responded to, ultimately driving better results for your campaigns. Some effective elements for writing subject lines include:

• Keep it Concise: Your subject line should be short and to the point. Aim for 6-7 words or less. For example, a concise subject line might be "Exclusive Offer Inside!"
• Make it Clear: Make sure your subject line clearly communicates what your email is about. For instance, if you're sending a newsletter, your subject line could simply state, "Your Weekly Newsletter is Here!"
• Ensure it’s Relevant: Your subject line should be relevant to your target audience and align with their interests. For example, if you're sending an email about a sale on outdoor gear, your subject line could be "Discover Your New Must-Have Adventure Gear!"

Techniques for Writing Effective Subject Lines

Your subject line should be concise, clear, and relevant to your target audience. It should also be attention-grabbing, personalized, and create a sense of urgency. A few fundamental techniques to keep in mind when writing your subject lines are:

• Use Action Verbs: Verbs like "Act Now," "Sign Up," or "Download" create a sense of urgency and encourage action. For instance, a subject line like "Don't Miss Out: Sign Up for Our Free Webinar" creates a sense of FOMO (fear of missing out).
• Ask Questions: Pose questions in your subject line to pique curiosity and entice readers to open the email. For example, "What's Holding You Back from Achieving Your Goals?"
• Use Humour: Humour can effectively grab attention and make your subject line stand out. For instance, a subject line like "How to Manage the ‘Terrible Twos’–Parenting Tips” can feel lighter and more personable than “Our Top 5 Parenting Tips.”

What Works and Why

Remember, a strong subject line should be concise, clear, and relevant to your audience. It should also create a sense of urgency, exclusivity, or curiosity to entice the reader to open your email. Here are some examples of strong subject lines and why they work:

"Your Exclusive 24-Hour Sale is Here!"

Why This Works This subject line is short, clear, and creates a sense of urgency. The use of "Exclusive" and "24-Hour" creates a sense of scarcity, making the reader feel like they need to act quickly. The phrase "is Here!" is also attention-grabbing and adds a sense of excitement.

"Unlock Your [Resource] Today!"

Why This Works This subject line uses a sense of exclusivity and scarcity with the word "Unlock," which makes the reader feel like they're getting access to something valuable, and the phrase "Today!" creates a sense of urgency.

"Your [Brand Name] Update: New Features Inside!"

Why This Works: You know your recipient already has a level of trust with your brand, as they’re subscribed to your newsletter, so including your brand name can help this email feel more valuable and legitimate. The use of "Update" implies that there's new and exciting content inside, and the phrase "New Features Inside!" is attention-grabbing.

"[Name], You're One Step Away from [Desirable Outcome]!"

Why This Works: This subject line uses personalization by addressing the reader by their name, making it more personalized. The use of "You're One Step Away" creates a sense of anticipation and excitement, making the reader want to open the email to find out what's next.

These subject lines use a combination of attention-grabbing language, personalization, and urgency to entice readers to open the email.

Common Mistakes to Avoid

Now you’ve got the key elements down, some great techniques to remember, and some examples of strong email subject lines to refer back to. Now, let’s cover what not to do when crafting subject lines. When writing your subject lines, try to avoid the following common mistakes:

• Using Spammy Language or Keywords: Avoid using words or phrases that are commonly associated with spam or scam emails, such as "FREE," "WIN," or "MAKE MONEY FAST." These words can trigger spam filters and make your email less likely to be delivered to your subscriber's inbox. Instead, focus on using clear and concise language that accurately reflects the content of your email.
• Being Too Vague or Unclear: Don't make it difficult for your readers to understand what your email is about. Avoid using ambiguous language or phrases that don't clearly communicate the purpose of your email. Instead, be specific and transparent about what your email contains. This will help build trust with your audience and increase the chances of them opening your email.
• Ignoring Mobile-Friendly Formatting: With most emails being opened on mobile devices, ensuring that your subject line is optimized for mobile is essential. Avoid using too much punctuation, abbreviations, or special characters that can make your subject line difficult to read on a small screen. Instead, keep your subject line concise and easy to read.
• Not Personalizing The Subject Line: Failing to personalize your subject line can make it seem generic and uninteresting to your readers. Try to incorporate the reader's name or a personalized message that makes the email feel more relevant and targeted. This can be as simple as using a greeting like "Hi [Name]" or incorporating a personalized phrase that reflects the reader's interests.
