Your customers Inboxes are crowded places and knowing how to stand out is key and your subject line is your first (and often only) chance to make an impression. Subject lines need to be a skilful combination of creativity, clarity, strategy, but overall, generate enough curiosity or desire for that all important click. In this guide, we’ll explore how to create strong subject lines that capture attention and boost open rates, along with some Conversion Rate Optimisation (CRO) examples that the Digital Marketing team at Iocea Mailer think are proven winners.
Keep It Short and Sweet:
With many emails being opened on mobile devices, it’s essential to keep your subject lines concise. A good rule of thumb is to aim for 50 characters or less. These shorter subject lines are easier to scan quickly, especially on smaller screens.
Example:
Personalisation is Key [if possible]:
People love to feel special, and personalised subject lines can dramatically increase open rates. Adding the recipient's name or referencing past behaviour (like a recent purchase) can grab attention and make the email feel more relevant.
Example:
Create a Sense of Urgency:
Urgency can be a powerful motivator, especially in a deal-rich online landscape. Whether it’s a limited-time offer, a flash sale, or the last chance to register for an event, creating urgency can push recipients to open your email right away instead of leaving it for later (or forgetting about it altogether).
Example:
Use Numbers to Increase Curiosity:
Numbers stand out in text and they also create a sense of specificity. Lists or numbered tips are popular because they tell readers exactly what to expect and can promise quick, digestible insights.
Example:
Ask a Question:
Questions naturally spark curiosity. A well-placed question in your subject line can create intrigue and encourage recipients to open the email to find out more.
Example:
Use Emojis to Add a Visual Hook:
Emojis can make your subject lines more eye-catching and convey emotion or urgency without taking up too much space. However, it’s important not to overuse them or include emojis that might confuse your audience.
Example:
Exclusive Deals and Rewards:
By offering exclusivity and personalisation, these lines make the recipient feel valued and encourage immediate engagement.
Problem-Solving Subject Lines:
These lines directly address the recipient’s potential pain points and offer a solution, making them likely to open the email for advice or products.
Testing and Optimising Your Subject Lines:
To truly maximise your email open rates, A/B testing your subject lines is essential. By experimenting with different approaches — whether it's adding personalisation, playing with urgency, or including emojis — you can see what resonates best with your audience. Remember, email subject lines are not just about getting clicks, but also about improving engagement, conversions, and ultimately revenue.
Think About Your Audience First The best email subject lines are the ones that speak directly to your audience’s needs, interests, and desires. When writing your next subject line, think about what will grab their attention and make them feel like opening your email is worth their time.
With these tips and proven examples, you’re well on your way to creating email subject lines that boost open rates and set your campaign up for success.
