How To Write A Great Subject Line

Email marketing is an essential tool for small business owners. Whether it’s reaching out to potential customers, engaging with existing clients, or keeping your network informed, the effectiveness of your emails can significantly impact your business's success. It helps you communicate directly with your audience, build relationships, and drive sales.

But no matter how compelling your email content is, it won’t matter if your emails are not opened. This is where your subject line comes in.

Over 50% of email recipients open emails based on the subject line alone. It’s the first impression you make and can be the deciding factor between an opened email and one that ends up in the trash.

In this email, we'll explore how to create great subject lines for your emails, ensuring they grab attention and encourage your recipients to open and read your messages.

Strategies for Crafting Great Subject Lines

1. Understand Your Audience

Knowing your audience is the foundation of any successful marketing strategy. For small business owners, this means understanding the needs, preferences, and pain points of your target customers. Tailoring your subject lines to resonate with your audience can significantly increase open rates.

Segmenting your email list by grouping your email subscribers based on certain criteria such as demographics, purchase history, or engagement levels will allow you to create more targeted and relevant subject lines.

2. Use Numbers and Lists

Numbers and lists can make your subject line more engaging and easier to digest. People often prefer content that is organized in a list format. For example:

  • 5 Ways to Boost Your Small Business Sales
  • 3 Secrets to Growing Your Customer Base
  • 5 Tips to Improve Your Email Marketing
  • Top 10 Tools for Small Business Owners

3. Ask Questions

Questions can spark curiosity and engagement. They make the recipient stop and think, increasing the likelihood of them opening your email. For example:

  • Are You Making These Common Marketing Mistakes?
  • Do You Know How to Improve Your Open Rates?
  • Is Your Business Ready for the Holiday Season?

4. Include a Call to Action

A direct call to action (CTA) can create a sense of urgency and encourage the recipient to open the email. For example:

  • Don't Miss Out on Our Exclusive Sale!
  • Sign Up Today for a Free Webinar!
  • Claim Your Discount Code Inside!

5. Personalize the Subject Line

Personalization can make your emails more relevant and engaging. Use the recipient’s name or reference their specific interests or behaviors. For example:

  • John, Here's How You Can Improve Your Marketing Strategy
  • Exclusive Offer Just for You, Sarah
  • See Your Personalized Recommendations, Alex

6. Create a Sense of Urgency or Curiosity

Creating a sense of urgency can prompt recipients to open your email immediately rather than putting it off. Similarly, sparking curiosity can make them eager to find out more.

  • Urgent Phrases: Use phrases like "Limited Time Offer," "Act Now," or "Don't Miss Out," “Last Chance,” “Only A Few Spots Left.”
  • Curiosity Phrases: Use teasers like "You Won't Believe This," "The Secret to...," or "Exclusive Tips Inside."

7. Keep It Short

Email subject lines that are too long can get cut off, especially on mobile devices. Aim for subject lines that are no longer than 50 characters. Shorter subject lines tend to perform better as they are easy to read and quickly convey the message. Clear subject lines that outline the content of the email can be very effective. For example:

  • Monthly Newsletter – July Edition
  • Update on Our New Product Launch
  • Important Information About Your Account

Verbs can inspire action and make your subject line more dynamic. For example, "Download Your Free Guide Today" is more compelling than "Free Guide Available."

8. Use Humor or Creativity

If it fits with your brand’s tone, using humor or creativity can make your subject line stand out and be memorable. For example:

  • Don't Be a Grinch – Save Big on Holiday Deals!
  • Our Secret Sauce for Success (Hint: It’s Not Sauce)
  • Why Did The Chicken Cross The Road? Find Out Inside!

9. Avoid Spammy Words

Certain words and phrases can trigger spam filters, causing your email to land in the spam folder instead of the inbox. Avoid using words like "Free," "Buy Now," "Earn Money," and excessive punctuation or capital letters.

  • Stay Authentic: Ensure your subject line reflects the content of your email. Misleading subject lines can harm your credibility and lead to higher unsubscribe rates.
  • Use Spam Check Tools: There are tools available that can help you check if your subject line is likely to trigger spam filters.

10. Offer Value

Your subject line should promise something valuable to the recipient. This could be a solution to a problem, a special offer, or useful information.

Focus on what the recipient will gain from opening the email. For example, "Save 20% on Your Next Purchase" or "How to Boost Your Sales Today."

Address a common pain point and offer a solution. For example, "Struggling with [Issue]? Learn How to Fix It."

11. Test and Analyze

Lastly, testing different subject lines and analyzing their performance is crucial. Use A/B testing to compare different subject lines and see which ones perform better. By sending two versions of your email with different subject lines to a small segment of your list, you can analyze which one has a higher open rate and then send the winning version to the rest of your list.

Make sure to change only one element in each version so you can accurately determine what made the difference. Look at metrics such as open rates, click-through rates, and conversions to determine what works best for your audience.

12. Review and Refine

Always review your subject lines for any errors or any improvements that you could make before sending your email. Over time, refine your approach based on what works best for your audience. Analyze the performance of previous email campaigns to understand what types of subject lines resonated with your audience.

Crafting great subject lines is an essential skill for small business owners looking to maximize the impact of their email marketing campaigns. By following the 12 steps listed above, you can significantly improve your email open rates and overall engagement.
