Email Subject Lines: 50+ Examples (& Tips) to Get More Clicks

Struggling to create email subject lines that compel recipients to click through?

Maybe one or two opens here and there. But overall, all those hours invested and… nothing.

Wouldn’t it be great if there was a way to create an inbox full of email open notifications because of stellar email marketing?

Imagine crafting up subject lines that invoke an irresistible desire to click left in your email campaign. 

Well, our post is here to help. 

We’ll take your hand and guide you so you’ll be able to create stellar email subject lines.

So, brush aside the tumbleweed, clear some space in your inbox, and let’s get started!

Your Email Subject Line Will Make or Break Your Email

The email subject line length is a 27-73 character (depending on the email browser) preview of the email’s content. 

Think of it as the ten-second teaser spot for a 2-hour movie. It provides a glimpse of what to expect.

According to Quickmail.io’s analysis of over 65 million emails and their email open rate, 47% of cold emails are opened based on the subject line alone. 

A good subject line taps into the behavior driver known as FOMO (Fear of Missing Out), while bad ones create a sense of MOMO (Mystery of Missing Out).

For example, “Email subject lines that helped Jon Morrow sell 10,000 copies of his book” would be worth opening. 

Whereas “ACT FAST OR YOU ARE GOING TO MISS OUT 😡” raises a few red flags.

To avoid your email subject line raising red flags, let’s look at ways to ensure that your email recipient reads your subject line and opens your email.

What are the Best Practices for Writing Email Subject Lines?

Seth Godin has said, “Why waste a sentence saying nothing.”

Here’s a checklist to ensure you say “something” and improve your open rates… 

Grab Attention

With the number of emails sent daily, those that grab the recipient’s attention will most likely be opened.

For example:

“Boost Your Bottom-line with this One Proven Technique by 50%” is more likely to entice your email recipient to open your email than an email subject line that simply says “Quick Question”.

The second email subject line is too vague, and who has time to read an email that can mean anything? 

Keep It Concise

MIT researchers found we can process information in as little as 13 milliseconds. 

That’s pretty quick.

We decipher and decide an email’s fate in less time than the blink of an eye. Keep your subject lines concise and to the point.  

Be Specific and Relevant

If your audience is blog writers, give them the best blog-writing info. 

If it’s a vegetarian blog, don’t send them the latest Sous Vide Steak recipes.

Irrelevant or wishy-washy information is a surefire way to get deleted.

Personalize When Possible

Research on over 7 billion emails found that personalizing email subject lines can increase open rates by roughly 50%. 

Take a moment and add that extra personal touch. It’ll pay off in the long run. 

Create a Sense of Urgency

Retail outfits have mastered this strategy. 

They make you feel like Jack Bauer in an episode of “24”. 

Action required. Urgent response. Please respond immediately. 

Black Friday ads are known to elicit this response in their email prospects.

So, follow their lead and create some urgency. 

Avoid Spam Triggers

Deemed malicious or fraudulent, spam triggers are words or phrases that guarantee a trip to the spam folder.  

Meet singles. Earn extra cash. Check order status. 

Stay clear of false promises, exaggerated claims, and risque material. 

Segment Your Audience

No blast emails here. 

Instead, segment your audience based on likes, interests, behaviors, and demographics.

Then provide them with relevant materials accordingly. 

Conduct A/B Testing

How do you know what’s working and what’s not?

A/B split testing.

Send out two different subject line versions to two separate groups of your subscriber list. 

The one that gets the highest open rate is the one you’ll use.

To see how these best practices work, the following examples and tips will guide you to crafting your own stellar email subject lines.
