While they may be only a tiny part of your message, email subject lines are arguably the most vital component of your email. After all, alongside the preheader, they are the only other thing recipients see in their inbox when they receive your email. Therefore, they determine if your email is opened and read or sent straight to the trash, or worse, spam.
What's more, if you're sending a cold email, the subject line is one of the first impressions a potential customer will get of your brand, meaning that a subject line greatly influences your open rates and, in turn, conversion rates.
Remember, you can dedicate hours of work and meticulously craft sophisticated content for your email campaigns, but that all goes down the drain if your target audience doesn't open the email.
So, want to stand out in a crowded inbox and increase your email open rates?
Then let's dive into some of the types of email subject lines that will skyrocket your clicks and open rates.
There’s no better way to generate more clicks than by piquing the recipient’s curiosity. After all, we humans are curious beings, so it’ll benefit you to maintain some sense of mystery and rouse the recipient’s natural interest in the subject line.
These subject lines require opening the email to receive the information and therefore result in a higher open rate. For example:
Open-ended questions, teasers, and exciting language are the key to these types of subject lines.
Did you know that last-chance email subject lines that instill a sense of urgency can generate a 22% higher open rate? It makes sense if you consider the fact that 56% of people have a fear of missing out (FOMO).
So, why not turn FOMO to your benefit? You can do this by setting deadlines and using words that generate more clicks. For example:
These types of email marketing subject lines remind people of their limited time left and encourage them to act ASAP. Therefore, generating more clicks and traffic for your company.
Some impactful words to consider that inject urgency into your subject lines are:
Limited Time, Last Chance, Still Time, Quick, Fast, and Now. Essentially, words that naturally express urgency are usually a good way to go.
One of the key elements of a successful email marketing campaign is your ability to understand your audience inside and out. Essentially this means understanding their needs, desires, and most importantly, pain points.
And to do this, you must develop detailed buyer personas. With these in hand, you’ll not only be able to appeal to your recipient's emotions when crafting your subject lines but also take the opportunity to compel them to open your email by presenting them with a solution to their problem. For example:
TL;DR: ensure that your email subject line tugs at a core desire, pique their interest, and tease a solution.
By now, we all understand how crucial personalization is to the business world - especially if you wish to beat the competition. In fact, personalized emails have 29% higher unique open rates and 41% more click-through rates.
So, if you’re already taking the time to collect data on your potential customers to build buyer personas, why not take it a step further and use that data to personalize your email subject lines? It’ll demonstrate to your recipients that you've taken the time to understand their personal pain points and needs, catch their eye, and make them feel valued.
Here are some examples:
Always remember that personalization takes many forms: you can use the recipient’s first name, include an interest, use transaction history to offer other relevant products and services, take the extra step by remembering their birthday, and even use their location to target audiences based on what's happening around them.
There are countless other ways to personalize a subject line and make it valuable to the reader. Remember, the key is to make it relevant to the reader and motivate them to open.
