Optimize Your Emails: Tips for Subject Lines to Improve Performance

It's simple. Enhance your subject line – you'll enhance your email performance. Here's how you do it:

  • Induce curiosity. Create intrigue by teasing the content of the email without giving away too much. For example, "Unlock the secret to [Field] success inside";
  • Make it benefit-oriented. Be loud about the benefits the recipient can expect with the email. For instance, "Discover how to double your sales today!";
  • Include emojis. Those little images work wonders in creating visual appeal and helping your email stand out. However, use them judiciously and ensure they align with your brand and message. For example, "Find out your summer vibe☀️🏖️";
  • Ask a question. It's only human to seek answers, so posing a question in the subject line entices the recipient to open your email. For instance, "Are you ready to take your style to the next level?";
  • Social proof. Create credibility and trust from the first words – mention customer testimonials, reviews, and endorsements to entice recipients to open the email. For example, "Join thousands of satisfied customers today!";
  • Segmentation. Tailor your subject lines to specific segments, making your content look more relevant and exciting. For example, "5 ways to stop struggling with [Specific pain point]".

Why is a good email subject line important?

No matter how good your email marketing campaign is, if the subject line isn’t captivating enough, it’ll get lost in your inbox and will not be read. This is because subject lines are helpful in:

  • Captivating attention. When your email reaches the recipient's inbox, they see the subject line first. In other words, it grabs their attention and, if done right, motivates them to open the email, resulting in higher open rates;
  • Transparent expectations setting. A good subject line should reflect the email's content so the recipient knows what to expect after reading it;
  • Encouraging engagement. A compelling subject line has the potential to inspire the recipient to do more than just open the email. It can motivate the recipient to engage with the email's content, click on links, or take other desired actions.

Email subject line best practices

If you’d like to try your hand at creating subject lines, follow these best practices to craft a perfect one:

  • Personalize wherever possible. Use personalization to your advantage, include recipient's name and a reference to their past behavior or purchases in your subject line, and watch the open rates soar.
  • Create urgency or FOMO. Fear of missing out is a powerful driver to take action. Create a sense of urgency by including phrases such as "last time," "today only," "ending soon," and similar in your subject line.
  • A/B test regularly. Regular A/B testing of subject lines helps keep your finger on the pulse of what works and what doesn't. Try length, format, style, and content variations to find your perfect subject line formula.
  • Avoid spam trigger words. Certain words and phrases can land your emails in the spam folder. So, avoid such short phrases as "win," "urgent," "prize," "earn cash," and similar.
