When we think of tools for keyword research, we usually think of tools that help identify keywords for ranking purposes on Google. No one really associates SEO optimization with email marketing, for example, right? 

Well, not many people do, but SEO keywords can be successfully utilized in email marketing, nonetheless. 

This article will discuss how you can use keyword research tools to supercharge your email marketing campaigns.

The Benefits of Using Tools For Keyword Research in Email Marketing

You can use tools for keyword research to optimize nearly all aspects of an email message. Starting with the sender name, you can also use these tools to optimize your subject line, and the content itself.

What’s more, these tools can help you identify spammy words you may have been using in your subject lines.

And providing relevant (and personalized) content is one of the pillars of targeted email marketing.

There’s another benefit to optimizing your emails with keywords: it boosts the performance of the website they are linking back to. This is because:

  • Targeted content facilitates more clicks on links
  • Better subject lines improve open rates.
  • Subscriptions rise as recipients share your content due to its value.

Taking all this into consideration, it’s clear to see that using tools for keyword research can supplement your strategy, delivering an even greater ROI.

Here’s how you can use these tools to improve the relevancy of your email campaigns.

Use Keyword Research Tools to Optimize Your Subject Lines

Producing relevant content for your audience is the first step towards success. Now you need to get them to open your emails. This is where keyword research tools come into play again. Use them to craft subject lines for newsletters that will skyrocket your open rates.

Let’s say, for example, you are selling online courses in digital marketing. If you search the term “digital marketing courses” on an SEO keyword tool like Ubersuggest, you will notice two things:

Ubersuggest will give you detailed SEO information about any given keyword

1. The phrase has a high monthly search volume, which means it generates a lot of traffic.

2. It also has a high SEO difficulty, which means it is going to be difficult to rank for. This is important if your emails are linking back to your website.

Ideally, you want your keywords to have high monthly search volume and low SEO difficulty. And if you dig deeper into Ubersuggest’s “keyword ideas” section, you will find something that fits that criteria:

Use Ubersuggest to generate keyword ideas for your next email marketing campaign

As you can see, the phrase “digital marketing courses on Google” emerges as a prime candidate for use on both accounts. You can use it to create s subject line such as:

“Check out the best digital marketing courses on Google.”

You can also use Ubersuggest to search keywords by traffic, to look for content ideas, and much more. 

Grow Subscriptions With Keyword Research Tools

You may feel that using SEO keywords in emails on top of your website SEO is a lot of extra work. However, this approach can increase the number of subscribers organically, on top of increasing your open rates and click-throughs.

Inevitably, recipients will start valuing your emails more and more as they become more on point. That’s why it’s essential that you include sharing options in your emails. In doing so, you’ll allow subscribers to distribute your messages within their social networks. 

That, in turn, leads to building social proof – a crucial element of brand building. 

Avoid Using Spammy SEO keywords 

Not all SEO keywords will improve the relevancy of your campaign. Some keywords will make your email look spammy and trigger spam filters. Here’s a list of SEO keywords to avoid using in your emails:

Keywords that are too aggressive:

  • Do it today,
  • Don’t hesitate,
  • Pennies a day,
  • Take action now, and
  • What are you waiting for?

Keywords that cheapen offers:

  • Pre-approved,
  • Join millions,
  • Free membership,
  • You’re a winner,
  • Dear friend,

Words used to exaggerate claims:

  • Satisfaction guaranteed
  • All-new,
  • For instant access
  • The Lowest price, etc.

Keywords that scream “too good to be true”:

  • Free investment
  • Amazing
  • Cash bonus, etc.

Keywords that create unwarranted urgency: drastically reduced, important information regarding, 

  • Once in a lifetime
  • Supplies are limited,
  • Exclusive deal,
  • Drastically reduced, etc.

The key takeaway here is that it is very important to maintain a decently low spam rate. Why? Because the more of your emails are reported as spam, the lower your sender reputation score will be. And if your sender’s reputation hits rock bottom, ESPs could blacklist your IP address. Check out these tips to get rid of spam in emails.


You shouldn’t be using SEO keywords to replace important demographic information such as:

  • Age, 
  • Gender, 
  • Location, or 
  • Purchase history, 

Instead, you should be using keywords in conjunction with this data, which is integral to targeted email marketing. That will allow you to produce even more relevant content for your email recipients.
