Email subject lines are the first thing your prospects see when they receive your email. They are the first impression you make on potential customers. And getting it right can influence them to open your email.
35% of email receivers actually only open emails based on the subject line. It should therefore come as no surprise that creating effective subject lines is critical to your email marketing success.
In this blog post, we’ll explore the science behind successful B2B email subject lines. We’ll discuss the significance of subject lines, what makes one effective, and some tips for crafting catchy subject lines.
So, let’s get started!
“I always ask myself one question before opening an email pretty much solely based on the effectiveness of the subject line: If I open this email, will it be a waste of time?”Ginny Soskey, staff writer for HubSpot’s inbound marketing blog
Understanding the Psychology of Email Subject Lines:
Writing effective email subject lines requires an understanding of the psychology of how the human mind functions and takes decisions. The limbic system of the brain is in charge of processing emotions and making decisions. This is where psychological triggers come into play.
Emails that appeal to psychological triggers like curiosity, urgency, and social proof are more likely to be opened.
For instance, asking a question or teasing with information in the subject line might spark interest. Using phrases like “act now” or “limited time offer” can create a sense of urgency. Also, you can generate social proof by using phrases like “join our community of top-performing sales leaders.”
Have you ever employed any of these psychological triggers in your own email subject lines? Comment and let us know which ones have you used.
We’ll also discuss some great B2B email subject line examples that make good use of these triggers in the following section.
“If you used the subject line ‘Free Beer!’ then guess what? You’ll get a huge amount of opens. But unless the contents of the email actually pour your customers a beer, then you’ll have achieved nothing but short term response gain and long term brand harm.”Parry Malm, account director, Adestra
The Anatomy of Effective Email Subject Lines:
Let’s dive into the anatomy of effective email subject lines. There are several elements that contribute to successful subject lines, including length, personalization, and clarity.
Let’s start by discussing length. Generally speaking, shorter topic lines outperform lengthier ones. Keeping your subject line short and sweet can help grab your recipient’s attention and entice them to open your email. This is due to the increased propensity for consumers to quickly scan their inboxes and skim subject lines.
Next, important factor is personalization. Adding a personal touch to your subject line can make it feel more relevant and interesting. You can do this by including the recipient’s name, referencing their company, or highlighting a previous interaction you’ve had with them.
Research shows that personalising subject lines can increase open rates by up to 50%. Personalization can improve your overall engagement and raise the likelihood of an email being opened.
Finally, let’s talk about clarity. Your subject line should clearly and simply express the purpose or benefit of opening it. Make an effort to select a subject line that makes it clear to the reader what to anticipate from your email. Avoid using confusing or deceptive subject lines, as this could frustrate or create a lack of trust among your subscribers.
Let’s look at some real-world examples of successful B2B email subject lines. These examples demonstrate how various businesses have made use of length, personalization, and clarity to produce appealing and efficient subject lines.
“Last chance: Get your [product] free trial today.”
“Don’t Miss Out: 50% Off Our Best-Selling Product!”
These subject lines leverage urgency to generate FOMO (fear of missing out) in the reader and encourages them to take action.
“We’ve got [recipient’s company name] covered”
“Catherine, here’s an exclusive offer just for you and your team”
Here, the subject line uses personalization to make the email feel more relevant and tailored to the recipient.
“How [product] can help your business achieve [certain goal]”
“10 Must-Read Articles to Boost Your Business”
This subject line is clear and specific, and it appropriately summarises the email’s content.
“When it comes to email marketing, the best subject lines tell what’s inside, and the worst subject lines sell what’s inside.”MailChimp
Testing and analyzing Email Subject lines:
It’s critical to test and analyse your email subject lines to see what appeals to your audience. It’s common practise to compare two versions of an email to determine which one performs better using A/B testing.
For instance, you can experiment with several subject lines on a tiny subset of your email list to see which one gets the most opens and clicks. Once you’ve identified the winning subject line, you can use it for the rest of your email list.
Analyzing data is also crucial to understanding the effectiveness of your email subject lines. By tracking key metrics like open rates, click-through rates, and conversion rates, you can gain insights into what’s working and what’s not.
For example, you might discover that shorter subject lines with clear calls-to-action perform better than longer, more fuzzier ones. Or that personalised subject lines outperform generic ones.
By continuously testing and analysing, you can update your email subject lines for better results and engagement.
“If you aren’t split testing your subject line, start now. BUT, if you are split testing follow this cardinal rule: Be creative but don’t be crazy.”Parry Malm, account director, Adestra
Common mistakes to avoid when creating successful B2B email subject lines:
Have you ever opened an email that promised one thing in the subject line but actually included something completely different? Or perhaps a subject line in an email tricked you into clicking on it, leading you to discover that it was clickbait.
Let’s talk about some of the common mistakes that businesses make while crafting email subject lines and how you can avoid them.
Using clickbait or a deceptive subject line is a common mistake. Although it could encourage individuals to read your email at first, it can also damage your reputation and cause future open rates to decline.
Another error is using generic or vague subject lines. It is always essential to be clear and detailed about what your email contains so that your receivers will know what to anticipate and be more likely to respond to it.
Use the below tips to steer clear of these blunders and write compelling subject lines:
Be honest and transparent about the content of your email.
Keep your subject line short and to the point.
Make your email feel more relevant to the recipient by personalising it.
A/B test different subject lines to see what works best.
These tips will help you create subject lines that are clear, practical, and interesting while also boosting the effectiveness of your email marketing.
