How to Create Effective Sale Email Subject Lines

As mentioned earlier, you must use catchy email subject lines to grab your audience’s attention.

As such, let’s look at engaging email subject line examples and draw practical insight into creating good sales subject lines that draw the reader’s attention and increase outbound sales.

1. Communicate your offer in clear terms

Sales email subject lines example from Harvard

A good subject line should communicate the message or offer of the email. You must avoid confusion or ambiguity. Also, avoid using misleading subject lines. In this subject line example, Harvard VPAL clearly communicates its offer.

They show what they are offering and the reason behind it; that way, you get what the email is about and decide whether you want to jump on the offer. 

Subject lines that do not correctly represent the content of the email will reduce your sender’s reputation over time and may end up in the spam folder. 

2. Brevity is the new orange

Sales email subject line example from Typeform

When creating the best email subject lines, less is more. Short subject lines between 6 and 10 words or less than 35 characters are best.

This way, email recipients across devices can view the entire subject line and understand the email. In this example, Typeform keeps it simple.

The subject line is six words and has less than 35 characters. In addition, a report from Invesp shows that subject lines with 6 and 10 words had the highest open rates, followed by subject lines with less than six words.

3. Draw attention with curiosity

Sales email subject line example from The Motley Fool

When it comes to email marketing subject lines, curiosity doesn’t kill the cat. Rather, it draws them in. The best email subject lines arouse curiosity.

The Motley Fool draws the prospect’s attention in this email subject line example: “That’s expensive.” Even though it’s less than the recommended subject line length, it still works because recipients would most likely want to see what’s expensive. This is also a great tip to draw recipients’ attention to cold emails from the initial outreach.

This sales email subject line works because it taps into the basic human desire for discovery and the need to know more.

However, to have a high open rate, you would want to avoid deceiving the receivers or fooling them into opening the email since that may backfire horribly when they mark your email as spam.

4. Drive action through urgency

Sales email subject line example from Spotify

A practical piece of advice for creating the best subject lines is to create urgency.

This works because it taps into the human fear of missing out on a good deal. Subject lines that create urgency are great for sales, events, and promotional emails. In this subject line example, including “last chance” is a wake-up call for recipients who may have seen the previous emails but haven’t taken action because they know the offer is for a limited time. 

However, these events or sales must be realistic and not made up. Making up sales and events to increase your open rate can lead to recipients sending your email to the spam folder.

5. Don’t overdo your punctuation

According to research from Mailchimp, using no more than three punctuation marks in your subject line is recommended.

Your email may appear spammy with too many punctuation marks. In this sales email subject line example, Spotify uses one emoji and just one punctuation.

6. Don’t trigger the spam filters

Apart from grabbing attention and increasing the email open rate, the best email subject line also sets expectations for the email content and answers the prospect’s pain points.

This uniformity leads to a higher conversion rate and open rates in subsequent campaigns. However, inconsistency between subject lines and email body can lead to email recipients marking your email as spam.

Some words and phrases can also set off spam filters. Avoid using these trigger words and phrases when crafting subject lines to ensure deliverability.

Key Elements of Successful Sale Email Subject Lines

Now that we have looked at some examples of email subject lines, let’s look at the key elements of successful sale email subject lines. 

Personalization

The temptation to view customers as just numbers instead of individuals is particularly rife when crafting subject lines for sales. Yet, research has shown that personalizing email subject lines increases email open rate by more than 25%. 

Mailmodo says personalized subject lines increase email open rates by almost 30%.

Personalizing subject lines goes beyond using the name of the email recipient; it also includes showing an understanding of individual preferences and pain points based on past brand interactions.

Typically, personalized email subject lines include information about a customer, most commonly the customer’s name.

Still, it can also include information about their location, occupation, other personal details, interaction with your brand, or products purchased or added to the cart. 

Power words

Use power words in your subject lines for sales to stimulate your recipient’s emotional or psychological response.

When used correctly, power words can trigger intense desire, curiosity, anger, trust, fear of missing out, etc. The ultimate aim of power words is to influence email recipients to open the email, click the CTA, and complete the sales process.

While powerful words can be handy for increasing email open rate, using them to create good email subject lines requires some tact. Here are a few tips to remember when using power words to create catchy subject lines.

  • Understand your audience: When creating subject lines for sales, know who your prospective customer is, their education level, gender, pain point, etc. A good place to start would be creating an audience persona.
  • Define your purpose and goal: When writing good subject lines, you must understand your goals for setting up the campaign. This helps you develop the best value proposition and offer for your sales emails.
  • Be consistent: Power words for your email subject line must be consistent with your brand tone and identity.
  • Response: Consider what emotional response you want from the email recipient. Once you understand what emotions you want your target audience to feel, you can craft power words that evoke these emotions.

Example of power words you can use in your email subject lines

  1. Power words for FOMO: Bargain, before, best, big, billion, bonanza, bonus, cash, cheap, deadline, discount, don’t miss out, double, economical, exclusive, expires.
  2. Power words for curiosity: Astonishing, backdoor, banned, be the first, become an insider, behind the scenes, bizarre, black market, blacklisted, bootleg, censored, class full, classified, closet.
  3. Power words for increasing desire: Exclusive, irresistible, sensational, luxe/luxurious, captivating, indulge, exquisite, unforgettable, breathtaking, allure, enchanting, pamper, epic, crave, tempting.
  4. Power words for trust: Reliable, proven, authentic, credible, transparent, verified, dependable, ethical, honest, accredited, integrity, secure, genuine, reputable, trustworthy.
  5. Power words for fear: Caution, beware, threat, risk, menace, terrifying, panic, dangerous, vulnerable, dread, warning, hazard, nightmare, intimidating.

Subject line length

There has been a notable surge in global mobile phone users in the past decade.

A recent research by Return Path revealed that over half of all emails are now accessed through mobile devices. This trend holds significant implications for email marketers, given that most mobile email apps only showcase the initial 35 characters of an email subject line before cutting it off.

Consequently, this limitation might account for the higher open rates associated with concise subject lines.

Special offers

Including special offers in your email subject line is a great way to re-engage prospects who have shown interest in your brand.

Special offers work because they exploit the fear of missing out on a good deal. Therefore, when using special offers in your sales email subject lines, understand your target audience’s interaction with your brand to give them a personalized offer that will spur them to take action.

The key to successful sales email subject lines is a combination of an irresistible offer and personalized communication.

Writing subject lines that draw on a client’s history and interactions with the brand gives your customers the feeling that you care for them as an individual. 

Whether referencing past purchases, highlighting exclusive loyalty rewards, or creating urgency based on specific behaviors, this personalized approach not only entices recipients but also reinforces a brand-customer relationship that goes beyond transactions, resulting in higher engagement and conversion rates.

Strategies for Creating Audience-Centric Sales Subject Lines

According to research, 78% of people have admitted to backing out of a purchase due to poor customer experience. Additionally, more than 70% of customers consider the customer experience a major factor in their decision to purchase, and almost 90% pay more for a product if their needs are met. 

This poses a unique problem for marketers as they must implement strategies to meet individual customer’s needs.

This section discusses strategies for crafting engaging subject lines that resonate with various customer segments. Let’s dive into it.

Segmentation

Segmentation means aggregating your customers (email recipients) into groups or segments based on common characteristics such as demographics, location, prospect’s company position, behavior, or psychotropic factors so that you can better understand them and meet their needs.

Email segmentation aims to pinpoint specific customer groups so that email campaigns and product offerings can be tailored to appeal to them. 

Market segmentation assists businesses in reducing risk by identifying the items most likely to capture a customer segment and then drawing up strategies to promote and distribute those products. 

Segmentation is the first step when crafting an audience-centric subject line for your email marketing campaign. Your email recipients are more likely to open emails with subject lines that meet a need they have at the moment, or that fit their personality.

Aside from segmenting your customers based on their personality, demography, or location, consider segmenting them based on their interaction with your brand and brand message interaction.

For example, an eCommerce store can segment customers based on their website actions. Customers who added an item to the cart but didn’t make a purchase can be grouped together and offered a special offer they cannot resist. This will not only improve the open rate but also increase conversion.

Personalization

Personalization using EngageBay

According to a study by SmarterHQ, 72% of consumers engage only with personalized messaging.

You must understand your target audience to personalize your email subject lines. This goes beyond creating an audience persona and analyzing the data you have collected on your customers.

With the data collected, you can segment your target audience into different segments and craft a subject line and email body that resonates with the segment.

Personalization was also found to impact both engagement and conversions significantly. Consider all the revenue you could have generated if you paid more attention to treating your customers individually.

Even though adding names to your subject line is a powerful strategy, personalization goes beyond that. At the height of it, personalization aims to offer your customers what they need when they need it.

Consider this: a telltale sign of two close friends is that they are acquainted with each other’s personality, moods, and preferences. Because of this, they are more likely to give gifts themselves more thoughtfully than strangers would.

In the same way, your business, through interaction with your customers, must learn about your customers’ preferences at a given moment and craft subject lines to reflect the same.

When crafting a subject line, you must consider the location, the purchase history and preferences, and your customer’s interaction with your brand marketing material. 

For example, if you own an eCommerce store that deals in clothes, your customer’s location determines what kind of clothes and special offers your emails must include.

Customers in temperate regions are more likely to purchase winter clothes with extra insulation during winter. They will be looking to get special offers on these clothing items. If you send such emails to customers in tropical regions, they are less likely to open them.

Tailoring Subject Lines to Your Brand’s Voice

Maintaining a consistent brand voice across different marketing channels makes your brand appear consistent. This makes recognizing your brand easier, builds customer trust, and secures a potential partnership, especially for B2B brands.

In this section, we will guide you in aligning subject lines with the brand’s tone and the nature of the sale. 

Understand brand tone

Determine the tone of your brand, whether it is informal, formal, lighthearted, or professional. Ensure the subject lines speak to this tone to keep the brand identity consistent.

Adapt to the nature of the sale

The language used in the subject line should be influenced by the type of sale, such as a clearance event, product launch, or holiday promotion. Adjust the tone of the subject line to reflect the urgency or excitement of the sales event.

Incorporate brand keywords or taglines

When writing the subject line, use important brand keywords and taglines to foster brand recognition. This reinforces brand recall and strengthens the association between the subject line and the brand’s messaging.

Use humor or creativity appropriately

Funny email subject lines, if done well, increase the chances of sales conversion. So, if humor is part of your brand’s identity, use subject lines with a touch of humor or creativity. However, be mindful of the sales context to ensure appropriateness.

Highlight brand values

If your brand has specific values or a mission, ensure your subject lines reflect them. This builds a deeper connection with customers who resonate with the brand’s values.

Maintain clarity and consistency

Prioritize clarity in subject lines regardless of the tone or nature of the sale. With just a few words, entice recipients to open your emails. Additionally, customers should easily understand you.

Best Practices to Create the Best Sales Email Subject Lines

Follow these best practices to write subject lines that draw the reader’s attention.

Keep it brief

Your subject line should be as brief as possible while providing enough details to convey the meaning of your email. Although it’s not always possible, knowing which email clients your subscribers use can be useful.

It’s important to note that mobile apps, such as Gmail, typically remove content after 35-40 characters until the user pulls the notice down to view more information.

Divide your audience into segments

Avoid sending your entire list with the same generic subject line. Rather, divide your email list based on distinct groups’ demographics or behaviors, then create engaging subject lines for each segment.

Get personal

Consumers anticipate tailored content. The finest subject lines for open rates don’t just include each subscriber’s name; they also use unique data you’ve gathered about their interests or regions.

Remember to use only “zero-party data,” which is information that your subscribers have voluntarily and directly provided to you.

Be succinct and precise

Give your email an idea of what’s in the email’s body while adhering to the ideal length. Beyond the subject lines for sales, ensure you use appealing email templates and follow up with a clear CTA. inside the email in the subject line so they know immediately.

Employ language that motivates action

Clearly state your proposition at the outset. What action do you want your audience to take? What action do you desire from them?

Consume, buy, give, wear, unwind, or listen? Make use of verbs that enable readers to picture themselves acting. But be careful not to use spammy terms.

Emails should be sent on time

Campaign Monitor reviewed over 100 billion emails sent across their platforms to obtain the most comprehensive benchmark data and email marketing metrics.

In the end, they discovered that Mondays typically yield the best results. Additionally, the lowest level of participation was on the weekends.

A/B test your email subject lines

A/B testing allows you to test different variations of subject lines for each segment of your email list.

To do an A/B test on a segment of your email list, take a sample size, share it into two halves, and test the two variations of subject lines. After a preset period, consider the data to see which performed better based on your KPI (open rates, conversions, etc).

Common Pitfalls to Avoid When Writing Email Subject Lines

Here are the top mistakes to avoid when crafting the best subject lines for sales.

Misleading statements

Avoid using subject lines that promise something misleading or sensationalized. This can erode trust and lead to recipients reporting you as spam.

Overuse of caps lock or exclamation marks

Excessive use of capital letters or exclamation marks can trigger the spam filter. Use them sparingly to maintain professionalism.

Generic or vague phrases

Subject lines that are too generic or vague may fail to grab attention. Be specific and provide enough information to convey the value or content of the email.

Spam trigger words

Avoid using words that commonly trigger spam filters. These include terms like “free,” “earn money fast,” or “urgent.” Using such words can result in your email being marked as spam.

Too long or too short

Excessively long Subject lines may get cut off on some devices, while extremely short ones might need to provide more information. Aim for a balance, typically between 35-40 characters.

Unnecessary punctuation

Excessive use of punctuation marks, such as ellipses (…) or multiple question/exclamation marks, can make your subject line appear unprofessional. Use punctuation sparingly. We subject keeping punctuation to the end of the subject line alone.

Repetitive messaging

Avoid sending emails with subject lines that are too similar to previous campaigns. Repetitive messaging can lead to recipients ignoring or unsubscribing from your emails.

Integrating Sale Email Campaigns with Overall Marketing Efforts

One way to integrate sales email campaigns with overall marketing efforts is through marketing automation. It is like a funnel from the first time web visitors interact with your brand to when they make their first purchase. 

The number of customers reduces as they go from one stage to another.

The role of a marketing and sales team is to try to improve the efficiency of this funnel, to make sure that more quality leads, that is, people who are most likely to buy your product, move from one stage to the other to the next until they make a purchase.

With marketing automation, you make the process more efficient and less time-consuming. 

Here are a few ways marketing automation makes integrating sales email campaigns with overall marketing efforts possible.

  • Centralized customer database: Using automation software like EngageBay helps you maintain a centralized customer database, ensuring that all pertinent customer information, including interactions and preferences, is stored cohesively.

  • Integration with Sales CRM: Use EngageBay CRM to synchronize data seamlessly between marketing and sales teams. This ensures both teams have real-time access to customer information and interactions.

It’s also recommended to send emails between 2 and 5 times a month. Sending more than ten emails a month could annoy the customer and send you to the spam folder. We have found that 6-7 emails per month are a sweet spot, particularly for customers with a high open rate.
