What would you say is the first thing that catches your prospects’ attention in their inbox? That is right, email subject lines. They are undoubtedly the most integral part of your cold email outreach. In just seconds, the faith of your outreach success is determined.

How? Well, if you do not create catchy email subject lines, you risk getting your email deleted, your open rate becomes much lower, and you will be disregarded as Spam. Consequently, this ultimately leads to a lower number of warmed-up leads and closed deals. Furthermore, effort and time spent will go to waste.

Don’t panic. We’ve got your back.

In this article, we are explaining what the subject line is and why it is important for your email outreach. Furthermore, we are digging deep into catchy email subject examples, why they work, and help you create your golden subject line that catches your prospects’ attention immediately.

What Is An Email Subject Line And Why Is It Important?

Let’s start with the basics. When you open up email inbox, you can notice the 3 following components of the email message:

  • Senders’ name,
  • Subject Line, 
  • And Preview text. 

Email subject line is a text line next to the sender’s name, describing the title of the email message. In other words, it is an indication of what the message is about and why you should read it.

Email subject line communicates value, sets expectations, and entices recipients to discover more about the topic by reading the email message. 

Getting your email subject line just right will make you stand out in the sea of other emails and increase the open rate. In sales terms, this means increasing the chances of getting your message across and warming up leads so you can close more deals.

Another thing worth mentioning is the importance of the Preview Text

A preview text, aka preheader text, is a line next to the subject line that shows the beginning of your email message. In some cases, preview text can be custom-made if you use newsletter software or similar tools, but in most cases, it shows a preview of your message. That is why it is important to perceive them in synergy rather than separate components to make your outreach as effective as you can (but we will talk more about this below).

How To Write Catchy Email Subject Lines: Tips To Get Started

Email subject lines’ first and foremost purpose is to get your prospects to open up your email. In other words, you need to catch their attention and entice them towards this action. 

Therefore, make email subject lines mean something. Let’s go through a couple of steps to get started. 

1. Determine The Type Of Subject Lines

As a salesperson, especially when doing a cold outreach, your job is to set the tone of the email subject lines. There are many ways to do it – making bold, sweet, or commanding statements – but first, you need to figure out the email content. After that, write down the email core meaning, and choose the type of tone which best fits your outreach message, personality, and prospects’ preferences. 

The usual subject line types for sales are:

FOMO (Fear Of Missing Out)Catch limited time offer

Sneak peekA discount gift for you
Making an offer10% off lifetime offer
Statistics 92% of salespeople swear by this strategy
Directive Use this fantastic tip to improve sales
Pain point If you struggle with wasting time, use this hack

2. Straight To The Point 

Be clear and concise about your email subject lines whenever you can. The reason is that often prospects prioritize the emails by their subject line and order of reading/replying. For this reason, the email subject line should communicate what the message is all about and its importance. 

Avoid vague subject lines, such as “While I wait for your response”, that doesn’t show anything about the email content as it will end up at the bottom of the priority list, and prospects will eventually forget it.

However, this doesn’t mean you can’t get crafty with it. You can create wordplay such as “Let’s Taco ‘bout your performance”, create a theme as “Let’s schedule a coffee chat”, or even use the power words to enhance your catchy email subject lines.

3. Power Words In Email Subject Lines

Specific words can trigger an emotion in us on a conscious or subconscious level. Let’s take the word “happy” for instance. After reading it, you suddenly felt a slight uplift in your mood, didn’t you? What happens with the word “Sad”? You felt slightly down there, correct? 

Words are indeed powerful. So using specific words in subject lines can do the same for your prospect. To be more precise, using Power words can really catch your prospects’ attention and activate an emotion. Furthermore, if you put the Power word at the subject line beginning, it will draw even more attention.

Here are power words example list to catch your prospects’ attention and get them to open up your email:

Providing value:
– Inspire
– Learn
– Guide 
– Enjoy
– Proven
– Lifetime
– Discount
– Valuable
– Nifty
– Secret
Pain point focus:
– Ready
– Change
– Save
– Stop
– Avoid
– Easier
– Faster
– Improve
– Skyrocket
– Reach

Note: The important thing is to set expectations with power words, but be careful not to overpromise, as this will only annoy your prospects. And do not go overboard with them.

4. How Long Should Email Subject Lines Be 

On average, email subject lines should ideally be 4 to 7 words. If you need more words, aim for a subject line no longer than 9 words, which is the upper limit. Furthermore, contemporary inboxes can reveal up to 60 characters on average, depending on the email provider. 

Also, keep in mind that some people check their emails on mobile devices, which show only 41 to 50 characters. This roughly translates to 7 to 8 words. Therefore, to lower the number of characters, you need to remove any filler words, such as just, hi, thanks, going to, etc.

Note: If you plan to reach out to your prospects using LinkedIn InMail, you should know that the subject line character limit is 200 characters. To check out Complete Guide To LinkedIn InMails With Templates.

5. Use Subject Lines And Preview Texts In Synergy

As we mentioned earlier, the preview text is a line of text found next to the subject line. It shows the first couple of words of your email message. In addition, it can show custom text if you use a newsletter software tool. 

Preview text is just as important as the subject line – it is your chance to deepen the message and make it more effective to get your prospects to open up an email. 

Preview text is usually 35 to 90 characters long, depending on the email provider. To make a subject line and preview text work together, it is best to perceive a preview text as a collection of details that didn’t fit the subject line. Here is an example:

Subject line: 🎁 A discount gift for you
Preview text: Happy Women’s Day! Up until the end of March, you get a discount of […]

Note: To convince a prospect to keep on reading the email and perform the desired action, make sure you get your opening paragraph and a Call To Action right.

Email Subject Lines Best Practices [And Some Worst Ones To Keep Away]

Now that we’ve set the email subject lines basic steps, let’s go through the best practices and what you need to avoid.

Subject Lines Best Practices 

1. Personalization

Did you know that personalizing subject lines can increase the open rate by 22.2%? The increase in open rate happens because personalization creates a sense of familiarity in prospects. Furthermore, it comes across as genuine and that you care for them. 

Personalize your email subject lines using the following demographic, psychographic, and firmographic data:

  • Interaction with your brand
  • Their location
  • Years in the company
  • Current company
  • Interests and values

To gain a full understanding of how powerful personalization in outreach can be, check out our blogs on how to increase the level of personalization in outreach and how to personalize image and GIF to improve response rate.

2. Use Emojis In Email Subject Line

In modern days times, emojis can be a nifty tool to spice up your subject line. They are a friend in need to get your point across, make your email stand out in the inbox, and they cost only one character (speaking of saving the space in the subject line :).

To back this up, take a look at the following statistics:

Emojis in subject lines had an open rate of 56% higher than those without them.

Not bad, ha 🧐?

3. Include Numbers

Catchy email subject lines that include numbers achieve 45% higher open rates. This way, prospects will perceive your subject line as more precise and attract their attention. Use numbers to state how many tips you send them, time stamps, or statistics to increase the value.

4. Email Subject Lines Specifying Time

Providing your prospects with the right information that is in correlation with time will attract their attention as it represents information that is a “current trend”. Nicely timed subject line will increase an open rate, as well as response rate depending on the email body.

Example: 

Here is how to boost your April’s website performance

5. Hint The Valuable Content

One of the perfect ways to increase the open rate is to give your prospects a sneak peek into the body of the email. This catchy email subject lines’ teaser can be in the form of content that prospects will value, such as images, infographics, and guides with top 5 tips.

Example:

Why Sales Needs To Get Out There And Use Social Selling More (Webinar)

6. Subject Line Testing

You need to test your email subject lines to be sure you got them just right, and there are a couple of ways you can do it.

A/B Testing

Every audience is different, and in some cases, one subject line that worked previously won’t be that effective anymore. And then, there is the following fact:

A/B testing can increase email open rates by 49%

That is why you need A/B tests as much as possible. In order to do this, take 3 to 5 subject lines and send out those cold outreach emails to check which one has the highest open rate.
For example, in Skylead, you can test different subject lines for your outreach campaigns on autopilot and see which one works best for you.

Online Email Subject Line Testers  

Online email subject line testers are nifty tools to have at hand if you are not sure about the effectiveness of your subject lines. Whether you wish to test the emotional tone of voice or the overall effectiveness of your subject lines, you can use tools such as Send Check It, EMV Headline Analyzer, or GradeMyEmail.

Email Subject Lines DON’Ts

1. Hi There

Avoid phrases such as Hi there, Greetings George, or Hello. The reason is they aren’t specific enough and do not show any hint of what the email message is all about. Instead, draw your prospect’s attention by clearly stating the purpose.

2. Misleading Prospects

Being deceptive and promising your prospect one thing in the subject line and showing them another will annoy them. Consequently, you will lose trust and respect instantly. Not to mention, you will fail to close the deal with the prospect forever. Therefore, avoid click baits, or RE: and FWD: entirely just to get them to open up an email.

3. DO NOT USE ALL CAPS OR BUNCH OF EXCLAMATION POINTS!!!

See how that was unnerving and frenzy-like? Using letters in Caps Lock or with multiple exclamation points is a synonym for spammers these days. It also looks aggressive and distasteful, and you do not wish that for your brand, trust us. Furthermore, if you use this kind of email subject line, you risk getting your emails in the Spam folder. However, Caps Lock and exclamation points are not prohibited – you can always use one from time to time to emphasize your statement, but please do not go overboard.

4. Avoid Spammy Words

Similar to all-caps-lock words and multiple exclamation points, spam words can also ruin your outreach efforts. These words have been all over the internet for many, many years (not to mention billiards in the 80s) and are now considered repulsive and plain out pushy. 

Here are a couple of examples to watch out for:
