6 Tips for Writing a Catchy Email Subject Line for eCommerce


Email marketing is a powerful tool for each eCommerce business to engage with customers and drive conversions. However, with inboxes flooded with numerous emails every day, crafting a catchy email subject line is essential to stand out and capture your recipients’ attention.

A compelling subject line can entice your clients to open your email, increase open rates, and ultimately drive conversions. Now we will explore several main tips for writing a catchy email subject line for eCommerce to help you boost your open rates and drive more sales.

Tip 1: Use Themed Subject Lines

Themed subject lines usually work better in emails for several reasons:

  • Emotional Connection

Themed subject lines (like Christmas, winter holidays, summer vacation, or spring email subject lines) can tap into the emotions and interests of your clients, creating a sense of relevance and connection. This emotional resonance can encourage people to open the email to learn more or take action.

For example:

  • “Zip Through The Christmas With Our Super-fast Elf-checkout!”
  • “An Egg-cellent Easter Basket For You!”
  • Increased Open Rates

A themed subject line can capture the attention of the recipient and entice them to open the email. It creates curiosity and intrigue, making the email stand out in a crowded inbox and increasing the chances of it being opened.

  • Clear Expectations

Themed subject lines can set clear expectations about the content of the email, helping your clients understand what they can expect inside. This can lead to higher open rates as recipients are more likely to open emails that they believe are relevant or interesting to them.

  • Brand Consistency

Themed subject lines that align with the brand or the overall message of the email can help reinforce brand consistency and recognition. This can result in increased trust and engagement from recipients, leading to higher open rates.

  • Differentiation

Themed subject lines that are creative, unique, and stand out from generic subject lines can help your email stand out in a crowded inbox. This can pique the curiosity of recipients and increase the likelihood of them opening the email.

Tip 2: Personalize and Segment

Personalization is a key strategy in email marketing, and it can start with your subject line. Using the recipient’s name or other relevant details in the subject line can create a personalized experience, make your email feel more tailored, and increase the chances of your email being opened.

Segmenting your email list based on various criteria such as demographics, purchase history, or engagement level can also help you send targeted subject lines that are relevant to specific segments of your audience. This can significantly improve the open rates and engagement of your emails.

For example:

  • “John, Your Exclusive Offer Awaits!”
  • “Hey, Fitness Lovers! Check Out Our New Collection!”
  • “Attention New Yorkers: Don’t Miss Our In-Store Event!”
  • “It’s Been a While, Here’s 15% Off Just for You!”

Tip 3: Ask a Question or Use a Provocative Statement

Asking a question or using a provocative statement in your email subject line can pique the curiosity of recipients and entice them to open your email to find the answer or learn more. This approach can be particularly effective when the question or statement is relevant to the recipient’s interests or pain points.


  • “Are You Ready for a Total Style Makeover?”
  • “Is Your Skincare Routine Missing This Miracle Ingredient?”
  • “Want to Double Your Sales? Here’s How!”
  • “Tired of Wasting Time on Chores? Discover Our Time-Saving Hacks!”

Tip 4: Create a Sense of Urgency

Creating a sense of urgency in your email subject line can be a powerful motivator for recipients to open your email and take action. By using words or phrases that convey a limited time or exclusive offer, you can create a sense of FOMO (Fear of Missing Out) that encourages recipients to open your email right away.


  • “24-Hour Flash Sale: Save Big on Your Favorites!”
  • “Only 3 Hours Left! Grab Your Discount Before It’s Gone!”
  • “Limited Stock Alert: Get Yours Before It’s Sold Out!”
  • “Don’t Miss Out: Last Chance to Redeem Your Free Gift!”

However, be cautious not to create false urgency or overuse these tactics, as it can lead to a loss of trust and credibility. Make sure the urgency is genuine and aligns with the content of your email.

Tip 5: Keep it Short and Sweet

In today’s fast-paced world, attention spans are shorter than ever, and your email subject line has to make an impact in a split second. Keeping your subject line short and sweet is crucial for grabbing attention and encouraging recipients to open your email. Aim for subject lines that are 50 characters or less to ensure they are fully visible to most email clients.

Avoid using long and convoluted subject lines that may get cut off or require recipients to read the entire line to understand the message. Instead, focus on concise and impactful words that convey the essence of your email. Use action words, numbers, and compelling language to create a sense of urgency or curiosity.


  • “Limited Time Offer: 50% Off Storewide!”
  • “Last Chance! Don’t Miss Out on Our Spring Sale!”
  • “Introducing New Arrivals: Shop Now for 20% Off!”
  • “Get Ready for Summer: 10 Must-Have Beach Essentials!”

Tip 6: Test and Optimize

Experiment with different subject lines and track their performance to optimize your email open rates. A/B test your subject lines to see what resonates best with your audience and make data-driven decisions to improve your email marketing strategy.

Before starting the A/B test, establish clear goals for what you want to achieve. Maybe, you plan to test the use of emojis, personalization, or different wording.

Summing Up

In a world where inboxes are flooded with emails, writing a catchy subject line for your eCommerce emails is more important than ever. By following the six tips shared above, including using themed subject lines, personalizing and shortening them, leveraging curiosity, testing emojis, and analyzing results, you can create subject lines that capture attention and entice recipients to open your emails.
