How Our Email Subject Line Analyzer Works

Our Email Subject Line Analyzer enables you to write irresistible subject lines that get your emails opened and read. Here’s how our tool works.

Step 1: Enter an Email Subject Line

To determine how clickable your email subject line is, submit your desired subject line for analysis.

Step 2: Review Your Email Subject Line

Once you submit your subject line, you’ll see a detailed analysis on how enticing it is and recommendations on making it more click-worthy.

  • Overall score: For best results, strive for 70 or above.
  • Case: Title case subject lines tend to perform better than a lower-case subject line
  • Word count: Subject lines with 4-6 words are known to perform best with the highest open rate
  • Numbers: Email subject line with numbers are proven to get opened more.
  • Character count: It’s recommended to keep your character count around 20 for best results.
  • Emoji count: Using emojis in your subject line makes your subject line stand out in the inbox.
  • Power words: Use emotionally triggering power words in your subject line that increases the open rate.

Step 3: Refine Your Subject Line Based on the Analysis

How to Write an Irresistible Subject Line to Increase Open Rate

Did you know that an average email subscriber receives 13 commercial emails a day and only around 20% of them are being opened (over 2 per day)?

That means unless your subject lines are captivating enough your emails will be buried in your recipients’ inbox without getting noticed.

So, how would you write an irresistible email subject line that stands out?

Well, there is no magic formula to write one. However, there are a few different success factors that mean the difference between a subject line your subscribers will notice — and open — and a subject line that they’ll skip right over. Let’s take a look at those success factors below:

  • Scannable: A perfect subject line quickly captures users’ attention.
  • Perfect word balance: Capturing attention is only half the battle. A perfect word balance encourages clicks and improves your emails’ open rates.
  • Straight to the point: Briefly explain what’s in your email. Don’t exaggerate and create misleading expectations as it may reduce your ultimate conversion.

Make Your Subject Line Scannable

If you want to create an email that gets noticed and read, you’ll need to ensure your subject line captures users’ attention as they skim through the inbox.

There are a few ways to capture the user’s attention in the inbox.

Use Emojis:

emojipedia.org is the best resource to find emojis for your emails. Simply search for an emoji that you want to use and copy it to your email.

Use Title Case:

Title case subject lines tend to perform better than a lower-case subject line. There are a few different capitalization styles, such as Associated Press, APA, Chicago Manual of Style, or MLA Style.

If you want to automatically capitalize your subject line, you can use our headline analyzer tool.

Use Power Words

Capturing attention is only half the battle; ensuring your emails get opened is another equally important aspect of your email campaigns. Using power words in your subject line is one of the best ways to improve your open rates.

With that said, it’s in your best interest to avoid overpromising in your subject lines. Exaggerating your subject lines creates a negative impact on your reputation and adversely affects the final conversions.

Come Up With 2-3 Subject Lines

Your first subject line may not always be persuasive enough.

That’s why smart marketers always come up with multiple subject lines for their emails.

In fact, writing multiple subject lines enforces you to write each of them from different perspectives. That way you can refine your original subject line and make it more click-worthy.

Use Our Email Subject Line Grader

Now that you’ve used our email subject line analyzer to come up with multiple subject lines, be sure to test them with our email subject line grader. It gives you a visual representation of your subject line so you can see how it will be seen in your recipients’ inbox. Plus, this tool also enables you to evaluate your subject lines on a scale of 1-100.
