Get Higher Open Rates with 22 of the best email subject lines

If you’ve ever sat down to write an email, you’ve probably asked yourself: “what if no one opens my email?” 

Not a fun feeling, right? Especially if you’re worried that the success of your email rides entirely on your subject line. It’s basically the thing that will make subscribers want to open your message. 

Thankfully, there are formulas to help make writing the best email subject lines as easy as pie. 

These 22 subject line formulas will help you write catchy subject lines that make subscribers eager to open your emails in no time.

Descriptive subject line formulas

The best email subject lines give your subscribers instant value. How? Tell your subscribers exactly what they can expect from your email using just your subject line.

Want to stand out in the inbox? Then a shorter subject line may be the best strategy.

If you want to make sure your subject line is fully visible — no matter how or when your subscriber receives your message — the best email subject lines may be short.

Example: Ready for Summer, Kelly? 

[First name], your free [product] is waiting for you

Example: Kelly, your free gift is waiting for you

Hey, [first name], we have an offer for you…

Hey, Kelly, we have an offer just for you…

Subject line examples with emojis

Only 6.9% of emails contain emojis. That means an emoji could help your message stand out in a crowded inbox — as long as it’s relevant and used with a purpose. 

In fact, one study found that — when used correctly — email messages that contain emojis in subject lines are opened 66% more than those without. 

Sounds promising, right? As with anything in marketing, you’ll want to test emojis in your subject lines to see if they resonate with your audience. You might be surprised. 

Here are some subject line examples that use emojis effectively.

Freshly using a bell emoji

Veestro using an explanation point emoji in its subject line

LFT Clothing using a rainbow emoji

Ikea using wave emojis in its subject line

Starbucks using a smiley emoji

Insomnia Cookies using cookie emojis in its subject line

Don’t forget about preheaders

Email preheaders are a powerful tool to increase email open rates. Not only do well-written preheaders give your subscribers more context for the email message, but creative preheaders can help give your email more personality. 

Subject line: [Ask a question]

Preheader: Here’s how


Subject line: Want to make more sales without spending hours prospecting?

Preheader: Here’s how

Subject line: [Product] is almost sold out

Preheader: Get it before it’s gone


Subject line: Protein cupcakes are almost sold out!

Preheader: Get ‘em before they’re gone. 

Subject line: [Case study] did [desired end goal]

Preheader: And you can, too!


Subject line: This entrepreneur launched a business in 1 week

Preheader: And you can, too!

E-Commerce subject line inspiration

Drive more sales by trying out email subject lines that educate your audience about your product and promotions. 

It’s/They’re here! [New product], just for you

Example headline: It’s here! New book releases, just for you

Buy 1 [product], get 1 free

Example: Buy 1 skirt, get 1 free

Last chance to save [discount] on [product]

Example: Last chance to save 30% off flights

Your [discount/offer] ends [time period]

Example: Your 25% discount ends at midnight

The one word subject line strategy

It’s hard to call a one word subject line a formula. But, yes, you can send subject lines with just one word. Nothing incites curiosity quite like a vague, but relevant, subject line. 

Let’s look at a one word subject line example:

One word email subject line example

Thanks to genius use of pre-header text, we know there’s a big clearance sale. But this simple, one word subject line makes the reader interested. Don’t you want to see what all the fuss is about? 

This strategy is useful if your goal is to drive traffic back to your website, too. In fact, one entrepreneur increased his website traffic by 83% using a one word email subject line that hinted at the email contents. 

Now that’s impressive. 

Writing effective subject lines is an art and a science. 

These email subject line formulas are meant to inspire you and help you think about your approach to writing. But don’t be afraid to experiment and try out some creative writing of your own. 

Our best advice? Get creative! Try out different subject lines and test them to see what works for your audience.

3 Tips To Help You Get Your July 4th Email Opened

3 tips to help get your July 4 email opened

As the U.S. prepares to celebrate Independence Day, there’s another holiday trend Americans can expect to look forward to: July 4th promotional emails.

Whether you plan to host a huge sale, offer exclusive discounts or simply take a holiday spin on your typical content, getting your emails to stand out in the inbox can be a doozy – especially when there are hundreds of other businesses tying the holiday to their emails too.

So what can you do?

Here are three tips to keep in mind when writing eye-catching subject lines for your July 4th emails. 

Use time-sensitive words, like “July 4th” or “Fourth of July”

Create a sense of FOMO — or fear of missing out — with your subject line. This is one of the most effective psychological drivers of email opens.

Referencing specific dates in your subject lines creates a sense of urgency with your subscribers, and ultimately encourages more subscribers to open your emails.

Plus, mention how long your promotion is running. Having a week-long sale? Be sure to mention it. This not only tells subscribers how long they can access the deal, it’ll entice them to act faster and take advantage of it as well.

Try subject lines like: “This Week Only: Hot July 4th Sales!” or “The 4th of July continues with 60% off!”

Be clear and concise, rather than creative

It’s tempting to get creative with your subject lines. Witty always wins, right?

Unfortunately, not always.

Subject lines that are direct and relevant to your audience often receive stronger open rates than subject lines that aim to be clever. That’s because subscribers want to know exactly what’s inside the email and will open if they feel it’s relevant to them. 

So instead of subject lines like “Sales That Even Uncle Sam Would Want,” try getting more specific with something like, “50% off Patriotic Tanks & Tees for July 4th!” 

Related: 6 types of subject lines that will improve your open rates. 

Send your email before or after July 4th

Keep in mind that your subscribers may not be paying close attention to their inboxes on July 4. Consider sending your holiday email before or after the holiday when they’re more likely to open it. Plus, it’ll also give you an edge over the competition. 

Considering a post-holiday message? You might want to try a subject line like, “We’re Still Celebrating July 4th: Buy One, Get One Cupcakes!”

Or, if you want to get a head start, try a subject line like, “Ready for this early July 4th deal?” 

Start creating your July 4th email

Sending holiday-themed emails keeps your brand relevant, but be sure to keep these tips in mind for success.
