Crafting Compelling Email Newsletter Subject Lines

Written by Bloody Marketing


Email newsletter subject lines are the gatekeepers of subscriber engagement. The short, pre-header texts that appear in an email inbox, summarising the content of the newsletter. Additionally, entice recipients to open the email. They act as the first impression for your newsletter content and hence, play a crucial role in determining whether subscribers engage with your message. A captivating subject line can entice readers to click. However, a bland one gets relegated to the dreaded “delete” pile. Here, we explore strategies for crafting email newsletter subject lines that compel subscribers to open your email and delve into your content.

Leverage Curiosity and Intrigue in Your Email Newsletter Subject Lines

Human beings are naturally curious. Effective email newsletter subject lines often spark curiosity and intrigue, as a result, prompting readers to want to learn more. You can achieve this by posing a question, hinting at valuable content within, or using unexpected phrasing.

For example, instead of a generic “Company Newsletter: July Edition,” consider:

  • Is Your [Industry Challenge] Holding You Back?” (This sparks curiosity about a problem your newsletter might address)
  • The Secret Weapon No One Told You About [Industry Topic]” (This piques interest by hinting at exclusive knowledge)

Emphasise Urgency and Scarcity

People respond to a sense of urgency. Email newsletter subject lines can leverage this by highlighting limited-time offers, exclusive content, or upcoming deadlines. However, avoid overusing urgency tactics, as it can come across as spammy.

Here are some examples:

  • Flash Sale: 24 Hours Only!” (This creates a sense of urgency for a limited-time offer)
  • Last Chance to Register for the Free Webinar!” (This emphasises a deadline for a valuable opportunity)

Personalisation: A Powerful Tool for Email Newsletter Subject Lines

Personalisation goes a long way in email marketing. Moreover, email newsletter subject lines can be personalised by incorporating subscriber names, locations, or previous purchase history. Further, this creates a sense of relevance and increases the likelihood of your email being opened.

For instance, instead of a generic greeting, consider:

  • “[Name], Here’s What You Missed This Week in [Industry]” (This personalises the message and highlights content relevance)
  • Based on Your Recent Purchase, We Recommend…” (This leverages purchase history for a targeted offer)

Keep it Short, Sweet, and Action-Oriented

In the age of mobile browsing, email newsletter subject lines need to be concise and scannable. Hence, aim for around 50 characters or less to ensure it displays fully on most devices. Additionally, consider including a call to action that encourages readers to open the email.

For example, instead of a long and descriptive line, consider:

  • Boost Your [Skill] with These Tips!” (Quick to read and gives you a reason to click.)
  • Read Now: 3 Free Tools to Simplify Your [Task]” (This is short, action-oriented, and offers a specific benefit)

A/B Testing for Continuous Improvement of Email Newsletter Subject Lines

The best email newsletter subject lines are often discovered through testing. Moreover, A/B testing allows you to compare different subject lines and see which ones resonate most with your audience. Additionally, this data-driven approach helps you continuously refine your approach and maximise open rates.

Refining Your Email Newsletter Subject Lines

Crafting captivating email newsletter subject lines is an ongoing process. While A/B testing helps you identify initially strong performers, it’s crucial to analyse the data from all your email campaigns to refine your strategy further.

Here’s how you can analyse your results and optimise your subject line strategy:

  • Track Key Metrics: Monitor open rates, click-through rates, and unsubscribe rates for each email campaign. Identify subject lines that consistently generate high engagement and those that fall short.
  • Identify Trends: Analyse which types of subject lines resonate best with your audience. Do questions pique their curiosity more than urgency tactics? Does personalisation significantly impact open rates?
  • Test Variations: Based on your analysis, test different variations of successful subject lines. For example, try tweaking the wording, phrasing a question differently, or adjusting the call to action.
  • Refine Over Time: Continuously learn from your data and iterate on your subject line strategy. This ensures your email campaigns remain fresh, relevant, and continue to entice subscribers to open your emails.

By analysing results and optimising your strategy, you can craft even more compelling email newsletter subject lines that consistently drive engagement and achieve your marketing goals.

The Secret Sauce of Email Subject Lines: Craft Lines That Drive Engagement

Crafting compelling email newsletter subject lines is an art and a science. By incorporating curiosity, urgency, personalisation, conciseness, and A/B testing, you can craft subject lines that grab attention, pique interest, and ultimately lead to higher engagement from your subscribers. Remember, a well-crafted subject line is the first step towards building a loyal and engaged subscriber base.
