Boost Your Email Open Rate With My Top 3 Subject Line Strategies


Anyone else able to spend HOURS browsing around a good bookstore?

I think there's just something so magical about being surrounded by all those books, getting a whiff of slightly musty paper as you walk down each aisle, hearing the whispers from thousands of stories just begging to be read.

But because I’m a babe on a budget and books are my biggest weakness (you too?), I usually have to set pretty firm boundaries on how many books I can buy on each trip to the bookstore.

How do I decide which ones are coming home with me and which ones go back on the shelf?

I POUR over the back cover blurbs until I find a book that speaks to my soul. One that I simply CAN’T put back down.

For me, that back cover blurb is make-it-or-break-it!

And guess what, babe?

Your email subject lines are make-it-or-break-it, too.

If you want your subscribers opening your emails (which, if you have an email list, I'm guessing you do!), a carefully crafted subject line is your email open-rate BFF.

Just like the blurb on the back cover of a book, your subject line is really the only thing your subscriber considers when making that split-second decision to pop your email open... or pop it straight into the trash can.

How do you write subject lines that get your emails opened? I'm so glad you asked. ;)

3 Types of Subject Lines That Will Get Your Emails Opened

There are three main strategies that I go to time and time again when crafting my own subject lines. These are my tried-and-trues, my go-to's, the fallback strategies that never fail to disappoint.

And today, I want to share them with you!


1. The Results-Focused Subject Line

As it sounds, this subject line hints at a big RESULT that your email content will help your subscribers achieve. But to get the scoop, they gotta open up!

The format for this type of subject line is usually along the lines of:

  • "How to achieve (result or goal) without (something they don’t want)"

  • "How to achieve (result or goal) in (time frame)"

  • "Here’s how to REALLY X (result or goal)"

Here are a few examples of this subject line strategy in action:

  • "How to triple your course sales this month”

  • “How to lose weight without restriction diets”

  • “How to spend more time with your family this summer”

  • “3 simple ways to 10x your productivity TODAY”

See how that works? Simple, to the point, but hinting at an email that’s highly valuable.

How to use this type of subject line

The R.F. subject line is great for those uber-value-packed emails your subscribers will be oh so eager to gobble up. Anytime you want to teach your subscribers something, give them a 3-step system, point out industry myths or mistakes… the R.F. subject line is a goodie!

The key to making this subject line strategy work for you is two-fold:

  1. Make sure the result you're promising is SPECIFIC and that it's something YOUR audience wants to achieve (not just any audience!)

  2. Be clear and upfront... but also make the result sound super juicy

For example, which of the following subject lines is more appealing to you? ↓

"How to get more clients"


"Get booked out with your dream clients in the next 2 weeks"


Pretty obvious that it’s the latter, right? That’s what happens when you get crystal clear, super specific, and make it sound juicy!

2. The Curiosity-Provoking Subject Line

Who doesn't love a little mystery in their lives every now and again, right? ;)

And that's exactly what this subject line serves up! Just the right amount of mystery and intrigue without being overly clickbait-y. If your subbies wanna solve the mystery, they have to open your email.

Here are a few great examples of curiosity-provoking subject lines:

  • "I almost puked right there on the spot"

  • "I can't BELIEVE I did this..."

  • "I've been keeping a big secret from you..."

How to use this type of subject line

Here are two of my favorite ways to use the C.P. subject line:

1. Ask a question that your subscribers can't answer without opening your email.

For example:

"Which one of these 3 are you?" (thanks to James Wedmore for that gem!).

The human brain is wired to seek out and find the answer to a question when it’s posed — which is why it'll be super hard for your subscribers to resist opening an email with a subject line like that!

2. Pull a juicy quote or line from within the email itself.

Scroll through the content of your email and look for one line that's particularly interesting or intriguing. Ba-da boom, ba-da bing: there's your C.P. subject line!

3. The BFF Subject Line

If I had to choose my favorite strategy, this would be it! And it's honestly super duper simple.

All I want you to do is think about the subject lines you write when you're sending an email to a close friend or family member. They're usually pretty short and low-key, right?

For example:

"What’s up?”

“Did you see this?”

“You free today?"

How to use this Type of subject line

Keep your BFF subject line short, sweet, and casual. When done right, the BFF subject line will look like you’ve sent it to a single person from your personal email account, rather than as a blast sent out to thousands of subscribers.

If you need some inspiration, pop open your personal inbox and look through actual subject lines from when you've emailed your friends and family. Are there any subject lines there that you can repurpose for your mailing list?

To date, two of my highest-opened subject lines have been:

"Hey girl" and

"What's going on?" — two BFF subject lines!
