Where to start when writing a sales email subject line

Just like the email copy itself, the email subject line demands preparation. Answering the questions below will steer you in the right direction. 

  • What is your offer?
    You know what you are selling. Just make sure to think of your offer not as a product, but as the value it can provide to the leads.
  • Who are you selling to?
    Think again of your target audience – their needs, their pain points, their motivations. Write your subject lines with the buyer persona in mind.
  • What is the goal of your email?
    What are you aiming at – opens, replies or conversions? Determining your final goal will help you compose a better-performing subject line.
  • Do the recipients know you?
    If you are emailing someone for the first time, you need to make a good impression and stay in their minds. But that is still relevant when writing to someone you’ve already had a conversation with. Only this time you also need to prove your credibility and evoke desire for further cooperation.
  • Do you have any mutual connections?
    If yes, use them! Using this information in the subject line will cause a rise in your opens as well as your chances for the final conversion. Why? The trust element of a mutual connection.
  • Do they want to open your email?
    Work with your recipients’ expectations. Do they ignore your emails? Make the subject line so tempting that any person (even a discouraged one) has a burning desire to open the email. Do they enjoy your emails? Use the subject line to fuel their feelings even more.
  • What kind of subject line performs best?
    Test, test, and test to study the recipients’ behavior and know what affects them the most.

Email subject lines for sales: best practices

Once all the questions are answered, you can proceed to developing your best email subject line. To convey the tone, excitement, and the message itself, it’s important to respect the subject line best practices:

Align the subject line with the message itself

The subject line should always match the content presented in the email. While clickbait email subject lines for sales are a somewhat effective strategy, the reaction can be unpredictable: most people forget the subject line the moment they open the email, but complete misalignment of the promised and the message itself can cause disappointment, loss of trust, or even anger, resulting in complaints and unsubscriptions.

Maintaining your reputation is one of the most important things in email marketing and tarnishing it to get a slight increase in opens is a bad trade-off.

Never miss the chance to use power words and emotional triggers

People are emotional creatures and you can easily appeal to their feelings and emotions through words right in the subject lines of your emails. Decide on the emotion you want to activate and use the corresponding emotional trigger words or power words. When used right, they can skyrocket the open rate.

Study and avoid spam triggers

Power words and spam trigger words go hand in hand. There’s a very fine line between the two. Always double-check if your subject line is getting too spammy using a list of spam trigger words (download the PDF to always have it hand) or use a specific tool like Subject Line Tester to get a detailed analysis of its spamminess. 

Optimize for mobile

Mobile has introduced its own standards, and the email subject lines have been affected too. On desktop, the displayed subject line length can reach well over 100 characters, while on mobile it’s usually around 30 characters (though these numbers may vary depending on the OS and screen resolution). That’s why the best subject lines for sales are predominantly short and can be displayed on all devices. Consider this (and the overall email optimization) if a significant chunk of your emails are opened on mobile.

Keep the email subject line length optimal

According to a B2B email marketing research, short subject lines (less than 5 words) show 65% better performance compared to long subject lines (8+ words). What’s more, long email subject lines are often viewed as a sign of low quality email content. Less is more.

Personalize the subject line

Remember the wise words of Dale Carnegie: Remember that a man’s name is to him the sweetest and most important sound in the English language.Want to craft the best email subject line for your sales offer? Personalize. 

This emotional connection to one’s name is backed by solid science: research proves that emails with personalized subject lines gain a 22% higher open rate compared to non-personalized ones. Of course, personalization goes way beyond the name so you can let your creativity flow (just don’t forget to add a fallback to your email variables). 

Sound natural

Yes, making a sale is your main goal. But establishing strong relationships with leads is the sub-goal that can significantly improve your KPIs for years to come. And it all starts with kind sincerity and natural speech flow. Don’t hesitate to let go of the polished structure and express your gratitude, ask for a meeting or a call, and start a real human conversation with a lead. 

Be fluid with your tone

You are trying to reach out to businesses, so it may seem only a serious tone is advisable. But that’s not quite so. You are reaching out to people, not machines. Be fluid with your tone – try casual and serious, humorous and all-business, but always have the recipient’s preferences in mind. 

Ask a question

The best way to engage the reader is through a question. Start your email subject line with a question to attract the recipients’ attention and provoke a response. Get even better results by using a question that challenges the recipient’s expectations or common knowledge. For example, Do you still think a 3% conversion rate is good?

Use numbers 

Numbers have a tendency to impress. They can also give you a little extra credibility. You have exact data to share (or at least you should have), so why not use it in a subject line? Show the recipient you aren’t just using big words to impress, you can back them up with numbers.

Experiment with the subject line format

Try humor, try mystery, try not trying at all and leave the subject line empty! But always track and analyze the recipients’ reaction. For example, emojis in email have proven to be a reliable way to increase both the open rate (for the subject line) and the CTR (for the email itself) among certain audiences. They also convey more meaning in fewer characters, appeal directly to emotions, and help your emails stand out in the inbox.

Test, test, test

You never know until you try. So why not compose at least two sales subject lines and conduct an A/B test? See which one performs better with your audience, and keep improving. When analyzing, take into consideration every metric detail – opens, replies, unsubscribes, spam report rates, etc, but keep your eyes on the main goal. Make sure you comply with the A/B testing rules to receive correct results.

Subject lines based on B2B personality types 📝

Every person is unique, that’s true. But we all share certain personality traits that allow us to create a few distinct groups and communicate with leads more efficiently. That’s exactly why every business creates buyer personas

There are four main B2B personality types based on which you can create the best subject lines for sales to grab the lead’s attention:

Type 1. Assertive

Self-confident and goal-oriented, they look for data, analytics, and straight answers. Their #1 goal is exact results. When they have information, they are fast decision-makers. Assertives do not ask questions, they prefer declaratives.

How to sell to Assertives

  • Stay professional at all times
  • Give complete answers. No half-way answers will satisfy their needs.
  • Get to-the-point. Assertives are not good listeners and won’t read long texts. 
  • Not just tell them about your offer. Demonstrate how Assertives will benefit.
  • Provide numbers. If you promise growth, state how big based on existing customers.
  • Set emotions away: you have higher chances to impress Assertives with ROI improvement from a testimonial than with an inspirational story.

Sales subject line examples for Assertives:

44. Want to improve {{company_name}}’s MRR by 50% in a month?

45. Save 8 hours a week with an all-in-one automation tool

46. By 2020, you will save $1,458. 

47. Your savings can grow by 75% in just 6 months.

Type 2. Amiable

This type of lead is calm and reserved, appreciates interpersonal relationships, loves informal conversations, and works on winning the respect of others. Prone to listening to every team member’s opinion, they are slow decision-makers. 

How to sell to Amiables

  • Address emotional rather than rational: Amiables will gladly listen to why some of your current customers came to you and what they appreciate about your product.
  • As they are slow decision-makers, you can lead them through the sales funnel from A to Z, so you’ll have a higher chance to gain them as brand fans.
  • Get ready to build not just professional relationships with Amiables but personal, too. This makes them feel safe and they can become more flexible in their decisions.
  • They are not fire-eaters so give them guarantees that they are safe with your company.  

Sales subject line examples for Amiables:

48. You are not the only one who wants to succeed 

49. Disappointed with {{leads_problem}}? {{testimonials_name}} had the same problem

50. Can I help you with {{leads_problem}}? 

51. I can share the secret of our success to help {{company_name}} grow

Type 3. Expressive

This type of lead is close to Amiable: they value friendship and want to stay personally connected even with partners. They are convinced in their truth and will do everything to persuade others. 

How to sell to Expressives

  • Do not concentrate on numbers and data: appeal to emotions rather than the rational.
  • Present case studies and describe the way your product or service has helped others. Expressives are more likely to react positively to such content. 
  • Emphasize that you appreciate long-term business relationships and are searching for them only.
  • To reach success with Expressives and gain their buyer’s attention, you need to constantly ask summarising questions, for example: “So you need a scheduling feature to send emails automatically?”

Sales subject line examples for Expressives:

52. A buyer persona image will make your business thrive

53. Stay ahead of your competitors with an automation tool

54. We know how you can connect with your leads

55. {{your_company_name}} knows how you can benefit from automation

Type 4. Analytic

Just as Amiables, they are slow decision-makers but unlike Amiables they love exact numbers and analysis. They will research you in full before replying to your email so get ready for a bunch of tricky questions they will want to get answers to. 

How to sell to Analytics

  • Prepare for a long sales process. Analytics will first research your service thoroughly and will ask you thousands of questions before coming to a decision.
  • Go into details as much as possible as they appreciate data. If you state that you have helped dozens of businesses, provide the exact number of companies you’ve helped and other relevant details: e.g. We’ve helped 10 companies grow their MRR by up to 25% in just under 6 months..
  • Do not rush them: this won’t just annoy them, but can change their minds completely and make them refuse your services half-way through the negotiations.

Sales subject line examples for Analytics:

56. Buyer persona development is the top pain point for 47% of businesses

57. Double your lead base starting at $29  

58. 1,000% reply rate growth: check out {{case_study}} to learn how you can improve your KPIs

59. With this tool, you will sell twice as much at half the cost
