Email subject lines should ideally be between 40-60 characters. This length ensures that the entire subject line is visible on most devices and email clients, avoiding truncation. Short and clear subject lines are more likely to grab attention and be understood quickly. Aim for brevity while still providing enough information to entice the recipient to open the email.

Personalisation in email subject lines enhances engagement by making recipients feel valued and directly addressed. Including elements like the recipient's name or relevant details can significantly increase open rates. Personalised subject lines resonate better with recipients, as they appear more relevant and tailored to individual interests or needs, leading to higher click-through rates and improved overall email performance.

You should A/B test your email subject lines regularly, ideally with each campaign or at least every few weeks. Continuous testing allows you to gather data on what resonates best with your audience, leading to more effective subject lines over time. Regular testing helps refine your strategy, improve open rates, and adapt to changing preferences or trends in your email audience.

Writing your own subject lines is generally preferred as it allows for more customisation and alignment with your brand's voice and audience. However, using a generator can be helpful for brainstorming ideas or overcoming writer's block. Combining both approaches—using generators for inspiration and personalising them to fit your specific needs—can yield the best results for engaging subject lines.

To personalise email subject lines effectively, use recipient-specific data such as names, past interactions, or purchase history. Incorporate these elements to make the email feel tailored to the individual. For example, "Jane, check out these exclusive offers just for you!" Personalisation increases relevance and engagement, making recipients more likely to open and interact with your email.

Creative use of emojis in subject lines can make your emails stand out and convey emotions or themes visually. For example, using a 🎉 can indicate a celebration or special offer. However, use emojis sparingly and ensure they align with your brand's tone. Test different emojis to see what resonates with your audience and enhances engagement without distracting from your message.

Effective subject lines for sales emails should highlight value, create urgency, and be concise. Use actionable language and include incentives like discounts or exclusive offers.
For example, "Unlock 20% Off Your Next Purchase—Today Only!" Incorporate personalisation if possible, and avoid spammy phrases to ensure your email reaches the inbox and prompts recipients to act.

For newsletters, subject lines should be engaging, informative, and reflective of the content inside. Use compelling language that teases the value or highlights key topics. Keep it concise and clear to ensure readability on all devices. Incorporate personalisation when possible and maintain consistency with your brand's voice to build trust and encourage regular opens from your subscribers.
