How to use power words?

Although you may know some of these power words, you may not get the desired results if you don't use them well. This segment discusses how to use these power words effectively in your email.

Power words in email

Power words in your email body can serve various purposes.

Whether it is to address the pain points of your customers, evoke emotions, create urgency, or persuade them to act on a call to action, they can help you achieve many things. 

For instance, if you are addressing the pain points of your audience, you can capture their attention by using power words that introduce the benefits of your products or services.

Grab their attention by specifying the solution you are offering. 

You can also combine sensory words with visual words or simply call on emotional power words to tell beautiful stories.

Meanwhile, if you want to appeal to emotions or create a sense of urgency, you will need power words that communicate such ideas. Some examples of power words you can include email body include:

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.

single word power power word example
  • 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. 

If you are not sure about these power words, here are some examples for you.

Power words in opt-in pop-ups

Email capture popups are also a good place to use power words, especially since they require a few seconds to attract the attention of your audience.

If you use the right words, you can hook your audience and entice them to perform the next action.

Power words in call to actions (CTAs)

As the name implies, call-to-actions compel individuals to act. One should not use weak words to direct your audience to carry out a specific action.

Instead, you use power words to entice and persuade them to click for your product/service. 

Note that CTAs consist of fewer words unlike the subject line of the email body. This is not to say that you cannot utilize longer words, but shorter power words are more effective and get the job done quickly. 

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

Examples include:

  • "Buy Now!"

  • "Grab your Copy Now!"

  • "Give Us a Call Today,"

  • "Don't Miss Out on our Free Offer Today,"

  • "Get Our Products at [figure] Discount,"

  • and more. 

Why should you use power words?

Selecting and using the right words is essential for every marketing copy you craft, especially when you want to cut through the noise, grab your audience's attention and boost your conversion rates—and that’s why power words are important. 

Power words attract prospects by evoking their emotions and compelling them to take your desired action.

Using power words can help you persuade your prospects to carry out any action actions — whether it is to :

  • purchase your products/service,

  • sign up for your email list,

  • read a blog post,

  • trigger curiosity through content on social networks with powerful blog post headlines,

  • create an intense desire to take on a call to action,

  • play on word choice to improve your click-through rates,

  • create better headlines or

  • make more money from your sales pages.

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.

example of exaggerated use of power word

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.
