The power of a compelling email subject line lies in its ability to command attention, evoke curiosity, and drive action – all with just a few well-chosen words.

Crafting effective email subject lines is an art that requires careful consideration and creativity. In this article, you’ll discover the secrets to writing the best email subject lines that captivate your readers, generate curiosity, and inspire action. 

Tips to Write Best Email Subject Lines

  1. Keep it short and sweet

Nigerian audiences, like many others, are bombarded with numerous emails daily. To grab a person’s attention:

  1. Keep your subject lines short and sweet.
  2. Aim for subject lines around 3-7 words or 20-60 characters.
  3. Avoid wordy phrases that might get cut off on mobile devices, leading to a loss of impact and relevance.

This is to ensure a compelling email subject line.

Example: “Your Exclusive Deal Inside!”

  1. Create a sense of urgency

Incorporate urgency into your business email subject lines to entice recipients to act immediately. Use phrases like “Last Chance,” “Limited Time Offer,” or “Ending Soon” to convey a sense of urgency, prompting your audience to open the email promptly.

Example: “Final Hours to Grab 50% Off!”

  1. Personalize where possible

When writing business email subject lines, consider addressing recipients by name, as it can create a sense of familiarity and connection. Personalization shows that you value your audience and can lead to higher engagement rates, leaving you with effective email subject lines.

Example: “Precious, Your Customized Savings Awaits”

  1. Create a curiosity gap

For the best email subject lines, spark curiosity in your audience by leaving a question unanswered or hinting at valuable information within the email. This technique encourages recipients to open the email to satisfy their curiosity.

Example: “Guess what made us 300% more productive?”

  1. Avoid spam trigger words

When writing a business email subject line, avoid spam trigger words that might send your email straight to the recipient’s spam folder. Common spam words include “free,” “money-back guarantee,” and “act now.” Instead, focus on authentic and genuine language so you can achieve the best email subject lines.

Example: “Unlock Exclusive Benefits for our Loyal Customers.”

  1. Test with A/B testing

To obtain the best email subject lines, A/B testing is a valuable tool for optimizing your email subject lines. Create two versions of your subject line and send them to a small audience segment to see which performs better. Use the winning subject line for the broader campaign.

Example: Version A – “Shop Now and Save Big!” | Version B – “Last Chance: Massive Savings Inside!”

  1. Avoid using all caps or excessive punctuation

Excessive capitalization or multiple exclamation marks can make your subject line appear spammy and unprofessional. For effective email subject lines, Keep it clean and avoid overusing special characters.

Example: “BIG SALE!!! 50% OFF EVERYTHING!!!!”

  1. Use emojis wisely

Emojis can add personality and catch the eye, but use them judiciously, ensuring they are culturally appropriate for your audiences. A smiley face or a Nigerian flag emoji can convey warmth and familiarity. 

Example: “:lol: Exciting News Inside: Check It Out!”

  1. Give a clear command

To craft the best email subject lines, here’s the thing – different strokes for different folks! Some folks out there appreciate direct instructions. So, if you’re sending an email with a clear call to action, like urging people to snag those event tickets, don’t shy away from letting your subject line mirror that. Embrace the power of being straightforward and watch your business email subject lines lead to signing that deal.

Example: “Join us at the Lord’s Garden”

  1. Segment your audience

Segmenting your email list based on demographics, interests, or purchase history allows you to tailor subject lines more relevant to each group. This personalized approach enhances engagement and increases the likelihood of your emails being opened.

Example: “Fitness Enthusiast? Check Out Our Exclusive Workout Gear Collection.”

  1. Leverage numbers and lists

When writing a business email subject line, using numbers and lists in subject lines can make your emails appear more organized and easy to digest. People are drawn to content presented in a structured manner, making it more likely for them to open your email.

Example: “Top 10 Time-Saving Hacks for Busy Professionals”

Crafting the Best Email Subject Lines

Crafting the best email subject lines for your email marketing campaigns requires a blend of creativity, cultural awareness, and strategic thinking. Remember, the subject line is the gateway to your email content. By keeping it short, creating urgency, personalizing where possible, and using power words, you’ll immediately capture your readers’ attention and entice them to open your emails.

Feel free to experiment and conduct A/B tests to find what works best for your audience. Through continuous analysis and optimization, you’ll unlock your email campaigns’ true potential.

So, as you sit down to craft your next business email subject lines, envision those eager subscribers on the other end, waiting to hear from you.
