Why are Email Subject Lines So Important?

Did you know that a majority of users, when looking at an email for the first time, use the subject line as a deciding factor between spam mail and normal mail. That means you have a 69% chance of ending up in the spam folder solely based on the subject line you choose for your email.

So is your subject line important? Heck yea it is!

Anatomy of The Perfect Email Subject Line

Writing a good email subject line is dependent on a few factors. You have to understand your target audience, look for cracks in competitors email strategies and then find a unique way to connect with your email newsletter readers.

The Proper Subject Line for Emails

A lot of marketers and small business owners try to find the perfect or proper method to writing attention-grabbing subject lines, but that should not be the case. Take a look at this simple subject line creation process we use:

  1. Understand your audience
  2. Sign up for your competitors' newsletter and track attention-grabbing email subject lines in a spread sheet.
  3. Compare your top 3 competitors
  4. Find a weak connecting point no one else is tackling. The subject line of your email should use this weakness to connect with readers

A great service that tracks competitor emails and gives you insights and reports is MailCharts. It helps you keep up to date with best practices, what your competitors are focusing on and it removes the hassle of subscribing and monitoring all those newsletters yourself. But if you go the manual route you can see that this method involves a bit of self-research and is unique to your own business and competition. You might find some great examples in your competitor's emails that you were previously not aware of.

The Subject Line Testing Process

Testing your subject lines using A/B testing is one thing, but looking at them for unique traits that help open rates is another. There are a few components that should always be considered as constants when looking at subject lines.

  1. Email Subject Line Length:
    According to data from marketers, 41 characters or 7 words is the perfect subject line length. You will notice that this length is actually 10 characters less than the average subject line length recommended. Sometimes short and sweet is better!
  2. Using Symbols in the Email Subject line:
    The use of emojis and symbols in subject lines is no new tactic. However, we noticed out of 13,000 sales emails we sent emails with symbols had a 12.9% higher open rate when compared to no symbols. It might not seem like a huge difference but when you increase your test sample size it could mean a few extra thousands in sales.
  3. Email Subject Line Capitalization:
    All caps in an email subject line might seem childish but depending on its length you might want to consider using caps. We noticed that short 1-4 word subject lines using all caps had a 33.8% higher click-through rate. Our favorite example of using all caps in an email subject line is pictured below in our Curiosity subject lines section.

Using this testing process you can get an idea for what to look out for and change when you send out your next email marketing campaign.

So if you are still wondering what is the best way to use your subject line to get more email opens and increase your open rates. We go over 10 types of subject lines that are a sure way to get you in the personal inbox on your first try.
