160 email subject lines that will explode your open rate

Want to increase your email open rates? Marketers who have higher open rates create email subject lines that their subscribers just can’t resist. In this guide, we’ll share 164 best examples of email subject lines that will increase your open rate.

Why you need good email subject lines

Did you know that 47% of recipients open emails based on the email subject line?

At the same time, 68% of recipients manage to distinguish spam from a more classic email, just with the email subject line.

In other words: your subject lines define the success or not of your email marketing campaigns.

The best way to write subject lines for higher openings (instead of being marked as spam ) is to take advantage of psychological trends and principles.

The following are 164 examples of the best email subject lines for email marketing.

Afraid of missing something

A psychological principle that is almost impossible to resist is the fear of missing out. You can use this fear in your email subject lines by adding an element of rarity (limited availability) or urgency (limited time).

Email subject lines that include words that imply time sensitivity – like “urgent”, “broken”, “important”, or “alert” – have been proven to increase email open rates.

Here are some examples of email subject lines for emails that use fear of missing out …

“Oh-oh, your prescription is going to expire”

“You’re missing something.”

“[URGENT] You have ONE DAY to watch this….”

“Your 7-figure plan ends at midnight….”

“Get this NOW before it’s too late….”

“Mary, earn twice as many points today only”

“Tonight Only: A Jeans Lover’s Dream”

These examples are taken from major brands like Jetblue, Guess, etc.

Humans have a natural desire to get things done, a curiosity that touches everyone. You can capitalize on this desire by leaving your email subject line open for subscribers to be curious, like a cliffhanger that can only be satisfied by opening the email.

You can make subscribers curious by asking a question (and responding to it in your email), promising something interesting (like photos or a surprise gift), or simply saying something that seems strange or unusual.

Here are some good examples of curiosity inducing subject lines:

“* Do not open this email *”

“Last day to see what this mystery email is about”

“10 Weird Habits That Make Millennials Richer”.

“Look at my new“ cave ”[IMAGE]”

“Is this the career everyone dreams of in marketing?”

“What they eat in prison is amazing”

“9 Disgusting Facts About Christmas”

“This is a hologram ?!”

“The fastest donkey in the world”

“? a surprise gift for you! {TO OPEN}”

Funny email subject lines

If your email subject lines make your subscribers laugh, they’ll just have to open it. Being humorous takes a little more thought and creativity, but it can pay off in terms of open rates.

Here are some fun email subject lines to make your followers laugh:

“Where to drink a beer NOW” (Sent at 6:45 am on a Wednesday.)

“Lick your phone never tasted so good”

“Agreements that make us proud (unlike our nephew, Paul)”

“We like to be used”.

“It goes well with spreadsheets.”

“If this is your wish”

“Need a day at the beach? Sniff your way to paradise…. ”

“Boom shakalak! Let’s start. ”

“Yes, I am pregnant. You can stop staring at my stomach. ”

“NEW! Holidays on Mars ”

“Look what you did, you little asshole…” (a mixture of curiosity and humor)

Everyone has a bit of vanity. People like to be loved, accepted, and even revered by others…. it is only part of the human being.

That’s why some of the smartest email subject lines use vanity to get you to open the mail. You can do this by either promising something that improves the subscriber’s appearance in the eyes of his peers or invoking the fear of being humiliated.

Here are some examples of smart email subject lines that take advantage of vanity:

Guess: “Don’t wear styles from last year.”

Rapha: “Gift inspiration for the discerning cyclist”

La Mer: “Age-defying beauty tips”

Pop Physique: “Get ready. “Keep the pie on your thighs.”

Rapha: “As worn around the world”

Sephora: “Products that celebrities wear”

Often used by Sephora and cosmetic brands in general.

You might not think of yourself as a “greedy” person, but it can be very difficult to miss out on a good deal… even if you don’t need the item right now. That is why the sales, specials and special offers work very well in your email subject lines.

However, be careful not to offer huge discounts – the higher the percentage, the less reliable the effect is on your open rates (perhaps because consumers don’t believe big deals are real).

Either way, you can usually expect to see an increase in your click-through rates every time you offer a discount in your email subject lines. This is probably because the people who open these emails are already interested in your offer, so they are naturally inclined to click.

Here are some email subject lines ideas for hitting your subscriber’s greed button:

“Meet your new jeans”

“Get a head start on summer”

“Flash. Sale. Alert.”

“New! essentials for your office ”.

“A new product has just been released! You will not miss it ”

“25% off your favorites”.

“Two offered for two purchased”

“A little luxury at a good price”

“Gift wrapping on all purchases”

“Get priority access.”

Another trait common to all humans is laziness or the tendency to avoid work. Even people who are not inclined to be lazy would prefer a straight line rather than a long, hard road.

You can give subscribers an easier way to achieve their goals by providing them with a shortcut, or a useful resource that saves a lot of time and energy.

Here are some examples of email subject lines that satisfy the lazy person. :

“ 63 essential points for writing a good email”

“Grow Your Email List x10 Faster With These 30 Content Ideas.”

“How to send an email to a busy person (included a verbatim script)”.

“Steal those email templates…”

“Create an ad in 60 minutes or less”

“212 article ideas for your blog”

Retargeting emails are sent to subscribers when they fail to complete an action or step in your sales process (for example, when they abandon their cart or don’t purchase after their free trial). These emails are used to bring your subscribers back to your sales process.

You can write compelling retargeting email subject lines by overwhelming objections, giving something to sweeten the deal, or warning them that something bad is going to happen if they don’t take action.

Here are some great examples of email retargeting subject lines :

“How to get your first 10,000 readers (tonight)”.

“Hey, did you forget something? That’s 20% off. ”

“The price has dropped for an item in your cart”.

“Marie, your account is on hold!”

“I am deleting your account”.

“This is my email”

“Did you miss any of these new features?”

“Good news: Your item’s price has dropped!”

“ Open. I have stopped working”.

“We are not going to abandon you!”

Personalized email subject lines

According to a 2015 study, email subject lines personalized by the inclusion of a name increases open rates by 29.3% on average across all industries.

But including the names of your followers is just one way to make your email subject lines more personal. You can also use casual language, share something personal, or use familiarity or friendship.

(Be careful not to overplay too much into believing that you are a friend!)

Here are some examples of personal email subject lines that catch your eye:

“Marie, look at these handpicked articles”.

“Happy Birthday Marie – Surprise inside!”

“Marie, do you remember me?”

“I didn’t see your name in the comments!”

“You come ?”

“You’ve changed”

“Shall I pick you up at 7?”

“Crazy Invitation, I am Going to Buy You Lunch….”

“Vanilla or chocolate?”

“I love you”

“Seriously, who’s doing this?”

“A quick favor?”

“Can you be free this Thursday at noon? [guest blogger] ”

”Your detailed results…”

“300% increase in turnover with just one box!”

“Thank you for helping us”

“Two razors for your friends (for us)”

Simple email subject lines

When in doubt, keep your topic simple and straightforward. Contrary to what you might think, those “boring” email subject lines can convert very well.

The key to making this work for your list is to always deliver value in all of your emails. Never send an email unless you have something important to say – always make sure your campaigns are full of value. If you do this, you will train your subscribers to open your emails, regardless of the email subject line of the message.

Here are amazing examples of email subject lines that get straight to the point:

Whatever technique you decide to use, make sure that your email subject lines are optimized for mobile users.

Originality is the key

Also, don’t forget that originality is the key to lasting success with your email subject lines.
