This post will give you the actionable strategies to create email subject lines that grab attention and drive engagement, meaning you will get your message heard.

Why Subject Lines Matter

First Impressions: Your subject line is the first thing people see, making it crucial for creating a positive impression.

Open Rates: A great subject line drastically increases your open rates, ensuring more people see your content.

Engagement: Compelling subject lines encourage readers to click, read, and engage with your email content.

Brand Building: Consistent use of effective subject lines builds your brand and improves customer loyalty.

SEO and Visibility: Although not directly related to Google SEO, great subject lines help you achieve visibility in your customer’s inboxes, improving your chances of being seen and building a loyal customer base.

The Psychology of a Great Subject Line

Before diving into specific techniques, it’s important to understand the psychology behind what makes people click:

Curiosity: People are naturally curious. A subject line that sparks interest will encourage them to learn more.

Relevance: Make sure your subject line aligns with the content of the email.

Benefit: Highlight the value the reader will get from opening the email. What problem does it solve for them?.

Urgency: Creating a sense of urgency can prompt people to act now rather than later.

Personalisation: Personalised emails feel more relevant and engaging.

Specificity: Be clear and specific about the email’s content; this builds trust.

Proven Techniques for Irresistible Subject Lines

Examples: “Are you making these common email mistakes?”, “Want to know the secret to higher open rates?”.

Use Numbers and Lists: Numbers and lists create structure and indicate clear value, making the email easier to process.

Examples: “Unlock”, “Discover”, “Secret”, “Ultimate”, “Powerful,” “Guaranteed”.

Personalise Your Emails: Use the recipient’s name or reference their local area to increase engagement and show you care.

Examples: “[Name], an exclusive offer for our loyal customers”, ” [Name], a personal invite to our [local area] event”.

Intrigue and Curiosity: Use unusual language or hints at a secret or strategy to make people curious.

Keywords: Use relevant keywords in your subject lines. Think about what your audience might search for in their inbox. For example, if you are a local gym, you might use keywords such as “local gym”, “fitness classes” or “personal training”.

Clarity: Use keywords naturally and ensure your subject lines are clear.

Consistency: Consistent use of keywords in your subject lines can help people find you more easily.

A/B Testing Your Subject Lines

No matter how well you write your subject lines, it is very important to A/B test different options to see what your audience responds best to. This means you create 2 versions of a subject line and test them with a section of your list to see which performs better.

Test different approaches: Try different combinations of power words, numbers, questions, and emotional language.

Analyse your results: Pay attention to which subject lines get the highest open rates and clicks, so that you can apply your learnings in the future.

Iterate and improve: Your subject lines are an on-going project. Always look to refine and improve your results.
