Use these tips and examples to craft email subject lines that encourage your customers and prospects to open and engage with your emails!
Most good email subject lines are like billboards in a recipient’s email. Their eyes gravitate towards them, and the best email subject for sales resonate quickly. Before you know it, you find yourself scheduling a demo.
You’re most likely reading this article to find some sales subject lines that work—and you will! First, let's discuss why your email subject line is so important and then move to some examples of attention-grabbing subject lines for sales emails.
What makes email subject lines good?
Let’s continue the billboard comparison: email subject lines need to balance between informative and persuasive. Flashy and professional. Intreginging yet offers a viewer value. Do you catch my drift?
The balance is critical if a sales representative wants their customer to notice and open their email. You need to earn your recipient’s time and attention! They’ve got their list of things to get done, so as they scan their emails, their brains search for try-hard subject headlines like “DON’T MISS OUT” or “Deal For You” to send to the trash.
Campaign Monitor says, “[Emails] that don’t accurately represent what’s inside will be judged accordingly: 69% of email recipients report email as spam based on subject lines alone.”
Put on your thinking cap because we’re not just writing good email subject lines for sales but email subject lines that improve your open rate.
Email subject lines that work for sales
A catchy subject line for sales encompasses humor, originality, and value. Of course, that’s a lot easier said than done. But good email subject lines don’t just come out of thin air!
The first step is understanding your audience. Narrow in on what and why you’re contacting this person or group of people. Here are some questions to help guide you towards the best subject lines for sales:
Who are they?
What are their primary needs, challenges, and interests?
How does your message solve their problem?
What are the next steps you want your recipients to take?
It will be beneficial to segment your recipients into different emailing groups. Prospects and current clients should be separate. Some customers may sign up for emails to get deals. Others may be interested in your content. The subject lines that might convince one group of readers to open your email may not work as well for your entire audience.
Sending the same sales email subject lines to an entire group of people isn’t the best use of time. Yes, it efficient, but is it effective? Nope. Test this theory by creating two different email subject lines to AB test, and see which performs better. It is worth the extra time when the collective open rate improves on all your emails.
Approaches to email subject lines
You can take a humorous approach. You can sound casual. You can state the facts. How do you know what's going to get someone to actually open your email?
Email subject lines can produce all kinds of emotions, but what emotions motivate people the most? Persado spent three years analyzing which emotion-based motivators best encouraged customers to take action. While there were 16 possible motivators the company explored, it found that achievement, exclusivity, and gratitude led the pack as the strongest motivators in 2021.
