Email marketing is a powerful tool to engage with your audience, promote products, and drive sales. But no matter how amazing your content is, if your subject line doesn’t grab attention, people won’t even open your email.
Writing an effective email subject line is an art, and learning how to craft one that converts can make a big difference in the success of your email campaigns.
In this article, I will share tips, strategies, and examples on how to write email subject lines that get opened, read, and lead to more conversions. Let’s dive into it!
Why Are Email Subject Lines So Important?
Before jumping into how to write them, let’s understand why subject lines are so important. Think of your subject line as the first impression of your email. It’s the first thing people see in their inbox, and it helps them decide if they want to open your email or ignore it.
A great subject line creates curiosity, urgency, or excitement, leading to more email opens and ultimately more conversions.
Research shows that 47% of people decide to open an email based solely on the subject line. That’s almost half your audience! So, spending time to write a good subject line is worth the effort.
1. Keep It Short and Simple
When it comes to email subject lines, less is often more. People have busy lives and short attention spans, so they don’t have time to read long and complicated subject lines. Try to keep your subject line short and to the point.
Ideally, aim for 40-50 characters (about 6-8 words). Shorter subject lines tend to perform better because they are easier to read, especially on mobile devices where screen space is limited.
Example:
- Instead of: “Check Out Our Exclusive Collection of the Latest Fashion Accessories and Save 20% Today!”
- Use: “Save 20% on Our New Collection Today”
Tip: If possible, test your subject lines to see which length works best for your audience.
2. Create Urgency or Scarcity
People are naturally drawn to urgent situations. When they feel like they might miss out on something important, they are more likely to act quickly. This is why using urgency or scarcity in your subject lines can increase open rates and conversions.
Phrases like “limited time,” “today only,” or “ending soon” can create a sense of urgency. It makes people think, “I need to open this email before I miss out.”
Example:
- “Hurry! 50% Off Ends Today”
- “Last Chance! Only a Few Hours Left to Get 30% Off”
Tip: Be careful not to overuse urgency, as it can lose its effectiveness if every email feels like an emergency.
3. Personalize Your Subject Lines
Personalization goes a long way in making your email feel more relevant and engaging to your audience. Instead of sending generic emails, try to tailor your subject lines to each recipient.
Using the recipient’s name, location, or purchase history can make the email feel more personal. People are more likely to open an email that feels like it was written just for them.
Example:
- “John, Here’s Your Exclusive Offer for 20% Off”
- “Special Deals Just for You, Mumbai Residents!”
Tip: Most email marketing platforms allow you to insert personalization tokens easily. Take advantage of this feature to make your subject lines more personalized.
4. Ask Questions
Asking a question in your subject line can spark curiosity and make people want to know the answer. When people see a question, their brains naturally want to find out the answer, which encourages them to open the email.
Make sure the question is relevant to the content inside the email. The goal is to pique interest without being misleading.
Example:
- “Need Help Choosing the Perfect Gift?”
- “Want to Know the Secret to Healthy Skin?”
Tip: Avoid asking questions that can be answered with a simple “yes” or “no” in the reader’s mind before they even open the email. Make it intriguing enough to encourage them to click.
5. Use Numbers or Lists
People love lists. They give a clear idea of what to expect and make the email feel more organized. Including numbers in your subject lines is a great way to set expectations and highlight the value of your email.
Example:
- “5 Tips to Boost Your Productivity Today”
- “Top 10 Must-Have Items for Summer”
Numbers make your email feel actionable and easy to digest, which increases the chances of people opening it to find out more.
6. Be Clear About the Benefit
Your subscribers want to know what’s in it for them. If your email offers value, make sure your subject line highlights it. Whether it’s a discount, useful information, or something free, let them know right away.
Clarity is key here. Don’t leave your audience guessing about the value of your email. Be direct and tell them why they should open it.
Example:
- “Get Free Shipping on Your Next Order”
- “Exclusive Guide: How to Increase Your Savings by 25%”
When your subject line clearly states the benefit, people are more likely to click because they know exactly what they’ll get.
7. Use Action-Oriented Language
Your subject line should encourage your audience to take action. Start with action words like “Get,” “Try,” “Discover,” “Learn,” or “Download.” This sets the tone for the rest of the email and nudges people toward clicking.
Example:
- “Get Ready for the Weekend with Our Special Sale”
- “Discover the Secrets to Better Sleep”
Action-oriented subject lines make your email feel more dynamic and engaging.
8. Avoid Spammy Words and Punctuation
While it might be tempting to use all caps or a bunch of exclamation points to grab attention, this can do more harm than good. Many email providers have spam filters that catch emails with spammy language or excessive punctuation.
Words like “free,” “winner,” “guaranteed,” and “cash” can trigger spam filters, and overusing symbols like “!!!” or “$$$” might land your email in the spam folder.
Example of What to Avoid:
- “WIN CASH NOW!!!”
- “GET FREE STUFF RIGHT HERE!!!”
Instead, focus on creating genuine interest without sounding overly promotional.
9. A/B Test Your Subject Lines
Every audience is different, and what works for one group may not work for another. This is where A/B testing comes in. By testing different subject lines, you can see which ones perform better and learn what resonates with your audience.
Try testing different elements like:
- Length of the subject line
- Use of personalization
- Urgency vs. curiosity
- Numbers vs. open-ended statements
A/B testing helps you fine-tune your subject lines to get the best results over time.
10. Use Emojis Wisely
Emojis can make your subject lines stand out and add a touch of fun. But be careful not to overdo it. Too many emojis can make your subject line look unprofessional, or worse, make it appear spammy.
Use emojis that are relevant to your message and audience. For example, a travel-related email could include a ✈️ or 🏝️ emoji, while a sale email might feature a 💸.
Example:
- “🌟 Don’t Miss Out on Our Special Offer!”
- “Get Ready for the Holidays 🎄 – 20% Off”
When used sparingly, emojis can grab attention and make your subject lines more engaging.
