Power words in email subject lines

Power words for subject lines must arouse urgency or excitement in your audience. They must elicit an emotional response from your audience. Why? Urgency or excitement prompt clicks. 

In other words, when you hold your subscribers to a deadline or let them know they can participate in an activity, you are indirectly persuading them to take an action.

Here are some situations that encourage you to use power words that evoke urgency or excitement.

  • Setting deadlines to register, buy, or sign up for a product or service
  • Inciting the fear of missing out on a special or scarce item. For instance, AliExpress used power words – huge discount- to attract its audience.
  • Informing them about a new/unique product
  • Informing them about a special item that isn’t readily available to the general public

Using power words associated with urgency or excitement encourages your customers to quickly take action because of the fear of missing out (FOMO).

Such powerful words have the ability to make your audience go from not-ready-to-buy to I-need-to-buy-it-now.

Power words in email preview 

Using power words in the email preview or email opening line can also influence whether the recipient would open your email or not — just like with your email subject lines.

Since you have to catch your readers’ attention within a few seconds, it is essential to use the right power words before they toss your email aside and focus on others. 

You can do this by using emotional power words or powerful words that create urgency, strike curiosity, or address your audience’s pain points.

You can also use sensory words to invoke imagination and get your recipients to read your email. If used correctly, your email may appear more substantial to your recipients.

Also, you can introduce power words to email previews through meaningful stats or trends. Since many statistics are available online, you can always find one that relates to what you’re talking about.

Note that an authoritative source must back up your claims to avoid smearing the reputation of your brand. 

Finally, you can use keywords to highlight the context of your email body.

Keywords make your email concise and give the subscribers a clear idea of what your email is all about. Such action influences the open rate of your emails.

This is because short power words are easier to read and won’t escape the reader’s eye.

Two Tools you can use to see if your power words work 


MonsterInsights headline analyzer allows you to check whether your power word is impactful and truly works. All you have to do is to insert the subject lines in the empty box and click on “analyze.”

Although the headline analyzer guides you in writing SEO headlines that drive traffic and help you rank better on the search engine result page, it also checks the strength of the power words in your headline by giving it a score, usually in the form of a percentage. 

For instance, the 25% score in the above image shows the power words in the headline, “5 proven tips to sleep better at night.

When compared with another headline, “4 ways to grow your business fast,” there were no powerful words to attract the audience’s attention.

MonsterInsight also recommends some power words for headlines which you may find useful.


CoSchedule is another tool to check if your power words work. Just like MonsterInsights, CoSchedule also has a Headline Analyzer feature that gives a detailed explanation of the words you use for headlines. 

CoSchedule analyzes each word by categorizing it into various segments – common, uncommon, emotional, and power words.

All you have to do is to input the coined headlines into the headline analyzer. 

It analyzes each word and measures its effectiveness by stating each score. If your power words don’t work, you will have a low score. 

To make your power words work, CoSchedule also gives out recommendations that you can use to boost your email conversion rate.  

Power words mistakes to avoid

Although power words are effective in getting marketing results, you still need to avoid some mistakes. Here are three mistakes you should avoid when using power words.

Excessive use of power words

When crafting marketing copy, it is okay to use power words sparingly to catch the reader’s attention. But going overboard with the power words can make you sound unrealistic. 

For instance, using “amazing,” “shocking,” and “unbelievable” in the same subject line could sound obnoxious to your readers. They could mark you as spam or view you as a dishonest person. 

The most essential point is to avoid using too many power words by striking a balance where necessary.

Making promises you can’t keep

In a bid to get results, many marketers often use alluring subject lines to attract their audience. For instance, here is an example.

Using power words to make huge claims relating to revenue or ROI can truly attract the audience.

However, if you fail to deliver your claims, you could mess up the trust you have already built with your clients. 

As a result, your audience could unsubscribe from your list or mark you as spam. In short, don’t promise what you can’t deliver. Always be realistic with your marketing copies.

Remember, the line between power words and spam trigger words is just fine.

Creating exaggerated urgency

Yes. Urgency delivers great results. However, you do not have to use the power words to create tension in the mind of your readers.

Words such as “limited,” “warning,” or “last chance” are effective only when you use them where they truly apply. Else, they will only result in a rift when it gets to your subscribers.

Key takeaways

  • Power words are simple to use and they drive the best result you can get. 
  • Don’t be a slave to some boring or generic words when you can utilize power words to boost your email conversion rate. 
  • But be sure not to overuse them because it’ll make your content sound spammy and exaggerated. Also, combining too many emotional power words makes your content ineffective and less prone to drive results. Only incorporate power words where they make sense.
  • Keep in mind that lust power words and anger words are generally associated with spam words. That’s why didn’t include them on our list of power words. But if your business call for them, be sure to use such words sparingly.
