Key Elements of a Funny Subject Line for Email

A well-crafted, humorous subject line can make the difference between an email that's opened and read or one that's overlooked.

Let’s delve into the key elements that make a subject line not only funny but also compelling enough to click.

1. Relevance and Timeliness

• Connect with Current Events or Seasons: Aligning your humor with recent events, holidays, or seasons can increase relevance and engagement. For example, during tax season, a subject line like "Even Your Inbox Deserves a Refund!" can garner smiles and clicks.
• Leveraging the current zeitgeist makes your message feel more immediate and connected to the reader's world, increasing the likelihood they'll engage.

2. Wordplay and Puns

• Creative Use of Language: Puns or playful twists on phrases can capture attention. A classic example is "We’re Not Kitten, This Sale is Purr-fect!" for a pet store promotion.
• Wordplay requires a moment of mental engagement, which, when resolved, delivers a small dopamine rush along with the humor, making your email memorable.

3. Personalization

• Incorporate the Recipient's Name or Interests: Subject lines that speak directly to the recipient can stand out. "Alex, Your Next Adventure Awaits!" can intrigue and feel personalized if you're in the travel industry.
• Personalization makes the email feel like it was crafted just for the recipient, increasing the value of the humor and the overall message.

4. Brevity and Clarity

• Keep It Short and Sweet: Email subject lines have limited space, and mobile devices display even fewer characters. A succinct subject like "Sale So Big, It's Scary!" is direct and humorous.
• Short, clear messages are easier for readers to digest quickly, making them more effective in grabbing attention.

5. Surprise and Originality

• Offer an Unexpected Twist: Surprise your audience with a subject line that turns expectations on their head. "This Email is Calorie-Free!" for a food-related promotion can elicit a chuckle.
• Humans are wired to notice and remember the unusual. A surprise in the subject line makes your email stand out from the predictable.

6. Testing and Optimization

• A/B Test Your Subject Lines: Not all humor lands the same with every audience. Testing different humorous lines to see which performs better can guide your strategy.
• Collect and Analyze Data: Use open rates, click-through rates, and engagement metrics to understand what works. This feedback loop is crucial for refining your approach.

Why Humor Works

Incorporating humor into your email subject lines can make your brand feel more human, relatable, and engaging. A funny subject line not only has the potential to increase open rates but also can positively affect the perception of your brand. Humor can break down barriers, making your message more welcoming and creating a positive first impression that encourages readers to engage with the content.

How to Implement

Start with understanding your audience deeply – what do they find funny? From there, experiment with different types of humor, from puns to cultural references, ensuring they align with your brand voice. Always keep the joke message relevant to the content of the email to ensure coherence. Remember, the goal is to entertain and then inform, creating a memorable interaction with your brand.

Best Practices for Email Subject Lines

1. Know Your Audience

Understanding your audience is the first step to writing email subject lines that resonate. What makes them click? What kind of sense of humor or tone do they appreciate? Emails tailored to your audience's preferences are 26% more likely to be opened (Campaign Monitor).

How to do it:

• Research your audience’s age, profession, and interests. Adding a personal touch, such as the recipient's name, makes funny subject lines even more engaging
• Use tools like surveys or analytics to gather data on what engages them.
• Adjust your tone for specific groups. For example:
  • Professionals: Keep it witty but professional. Example: "Meetings Cancelled? Just Kidding!"
  • Students: Add fun and energy. Example: "Homework? Let’s Procrastinate Together!"

2. Use Emojis Sparingly

Emojis can enhance email visibility, but too many can hurt your credibility. A single emoji can add a personal, fun touch while keeping the subject line clear.

Emails with one emoji can increase open rates by up to 56%, but excessive emojis reduce effectiveness (Emarsys).

How to do it:

• Stick to one emoji that fits your message. Example: "Weekend Plans? 🎉"
• Avoid emoji overload, which can make emails look spammy.
• Test emoji performance on your audience:
  • Playful brands: Use emojis to match tone. Example: 😊 or 🍕.
  • Formal brands: Use minimal or no emojis for a professional tone.

3. Be Short, Sweet, and Relevant

Long subject lines can be boring. People check their emails quickly and won’t read long ones. That’s why you should keep your subject lines short and clear.

What to do:

• Use 6-10 words only. For example: "Big Sale Today! 🎉"
• Add a funny twist to make people smile. Example: "Forget Pants, Shop Now!"

How to test relevance:

• Ensure your subject matches the email content.
• Include keywords that grab attention, like "funny," "deal," or "joke."

4. A/B Test Your Subject Lines

Not all funny subject lines will work for your audience. Testing helps you find out what clicks best. A/B testing is a surefire way to compare two subject lines by sending each to a small group of your audience. The one that gets more opens is sent to everyone else.

Testing shows which humor resonates with your readers. It increases open rates and helps refine your strategy.

How to do it:

• Create two versions of a subject line. Example:
  • Version A: "Laugh Out Loud Deals!"
  • Version B: "Deals So Good, You’ll LOL!"
• Use email marketing tools like Mailchimp to measure results.

5. Stay Brand-Appropriate

Your subject lines should match your brand’s personality. A funny subject line is great, but it has to fit your tone.

A mismatch confuses readers and lowers trust in humorous content. For example, a serious finance brand shouldn’t use over-the-top humor.

What to do:

• Keep your humor subtle for professional audiences. Example: "Save Money? That’s Serious Business."
• Use bolder jokes for casual brands. Example: "Pizza So Good, You’ll Forget Your Diet!"
• Always align with your target audience’s expectations.

6. Avoid Forced Humor

Humor is a powerful tool, but only when it feels natural. Forced humor can come across as awkward or even offensive, which might turn readers away.

What to do:

• Test your subject line with colleagues or friends. Ask if it feels funny or forced.
• Use humor that matches your brand identity. For example, a brand targeting business professionals might use subtle humor like "Finally, an Email Worth Opening!"
• Avoid using jokes that rely on inside knowledge or niche references unless your audience is highly specific.

7. Monitor Performance

After sending your emails, you need to know if they worked. Did your funny subject lines grab attention? Monitoring performance helps you learn and improve.

What to do:

• Track your open rates using email marketing tools like Mailchimp or Constant Contact. Aim for open rates above 20%, which is the industry average.
• Check click-through rates (CTR) to see if readers are engaging with your content.
• Analyze which subject lines performed best. For example:
  • "Oops! We Left You a Surprise 🎉" may outperform "Big Discounts Inside!"
• Make changes based on the data. If certain humor types work better, stick to them.

Pro Tips to Write Subject Lines that Match Your Brand Identity

1. Stay True to Your Brand Voice

Your subject lines should reflect your brand’s personality. Are you formal, funny, or somewhere in between?

What to do:

• Use language your audience expects from you. For example, a tech company might use, “Tech Deals You Can’t Miss!”
• A playful brand could say, “Oops! Did We Forget Your Discount?”
• Stick to the tone you use in all your communication, so your emails feel consistent.

2. Highlight What Sets You Apart

Your brand is unique, and your subject lines should show it. Let people know why they should open your email.

What to do:

• Mention something special about your product or service. Example: “Glasses So Comfy, You’ll Forget You’re Wearing Them!”
• Use humor to grab attention. Example: “Pizza That Pairs Nicely with Pajamas 🍕”

3. Incorporate Brand-Specific Keywords or Phrases

Using words and phrases that your customers recognize strengthens your message. It also makes your emails feel more personal.

What to do:

• Add words your audience associates with your brand. For example, a fitness brand might use, “Stronger You, Starting Today 💪”
• If you use funny phrases often, include them. Example: “Sweatpants Season? Yes, Please!”
• Keep the keywords natural. Avoid cramming too many into one line.

4. Adapt to Seasonal and Cultural Relevance

Your email subject line and lines should align with the time of year or trending topics. People love content that feels timely and relatable.

What to do:

• Use holidays or seasons to inspire your subject lines. For example:
  • Valentine’s Day: "Your Heart Deserves This Deal ❤️"
  • Summer: "Beat the Heat with These Cool Savings!"
• Tie into cultural events. For instance:
  • “Breaking News: Your New Favorite Product Just Landed!”
  • A sports brand during the Olympics might say, “Gold Medal Savings Await You!”

5. Maintain Consistency Across Channels

Your subject lines should match your brand’s tone across all platforms. If your website is serious, your emails shouldn’t suddenly be playful.

What to do:

• Keep your voice consistent. For example:
  • A luxury brand might use, “Exquisite Offers Await You.”
  • A fun brand could say, “Oops, We Dropped Another Deal!”
• Match the tone of your social media. If you’re formal on LinkedIn, avoid overly casual subject lines in your emails.
