Now, let's talk subject lines - a topic I'm truly passionate about.
Did you know that 47% of people decide whether to open an email based on the subject line alone? (source: Finances Online)
That's right, nearly HALF of your list is judging your email's worth based on a mere handful of words...
You could have the most brilliantly crafted email content,
but if your subject line fails to entice opens... it's all for nothing.
So if you're not happy with your email conversion rates, the very first step is to focus on optimizing your subject line open rates.
It's the lowest hanging fruit...
Think about it - if your open rates are low, your emails are going unseen, and your sales are suffering...
By simply getting more people to open your emails, you're automatically boosting your overall conversions...
Now, you might be curious...
What exactly is a "good" email open rate?
Zippia reports that the average email open rate across industries hovers around 21%. (source: Zippia)
At Digital Marketing All, our open rates consistently fall between 25-50%.
While that's certainly commendable...
Like any growth-minded marketer, we're always striving to improve, optimize, and outdo ourselves.
That's why, since the beginning of the year, we've been rigorously split testing ALL of our subject lines.
Our goal was to understand...
• What resonates most with our audience?
• What types of subject lines grab
their attention?
• How can we push MORE of our open rates closer to that coveted 50% mark?

After digging into the data and analyzing the top performers, we identified 5 foolproof strategies to instantly elevate your open rates...
Strategy #1 – Infuse Your Unique Brand Voice
Crafting subject lines that encapsulate your brand's distinct voice is always a smart move. This isn't about being cutesy or clever for the sake of it... It's about staying true to your brand. When your subject lines authentically echo your unique brand voice, you're fostering a deeper connection with your audience.
For example, a quirky ecommerce store could use subject lines like: "Socks so comfy, they'll knock your feet off! ?"
Whereas a serious cybersecurity brand might opt for: "[Alert] Critical security patch - install now"
Many of our highest-performing subject lines strike a bold, provocative, and even polarizing tone...
However, this aligns perfectly with our brand personality, which is why they work so well for us!
Now, if your brand voice is warm and nurturing, your subject lines should follow suit.
If your brand is known for its cheeky humor, infuse that into your subject lines.
If your brand voice is more buttoned-up and professional - please don't force edgy subject lines that clash with your style.
No matter what, never compromise your brand voice integrity just to chase a temporary spike in clicks.
If you need help nailing down your brand voice, Digital Marketing All offers expert guidance to craft your unique brand identity. Reach out to us to learn more!
Strategy #2 – Pose Intriguing Questions
Asking compelling questions in your subject line is an excellent way to hook your audience's attention with an open loop...
• Ask a question they're dying to know the answer to...
• Pose a thought-provoking rhetorical question...
• Zero in on a question that touches on their key pain points or challenges...
• Or simply ask a curiosity-provoking question that makes them eager to learn more.
Some examples:
ü "Are you making these 5 fatal SEO mistakes?" "
ü “What would you do with an extra $1K/month?"
ü "Why your dog hates his food (and what to do)"
This approach works wonders for boosting open rates - just be sure not to overdo it.
Strategy #3 – Leverage the Power of Numbers
Incorporating numbers into your subject lines is a phenomenal way to command attention!
This tactic works equally well for blog post titles, ads, and social media captions...
Numbers jump out visually, breaking up the monotony of plain text.
They also signal to readers that your content is specific and high-value.
Email subject lines with numbers have a 57% better open rate.
Plus, as humans, we're wired to love consuming information in list format, step-by-step guides, and numbered frameworks. It's why listicle-style content from the likes of Buzzfeed perform so well!
For example: "10 unusual ways to slash your tax bill" "5-step formula to write high-converting copy"
Let's say you had to choose between two emails...
• "Improve Your Email Open Rates" or • "7 Quick Hacks For Sky-High Open Rates"
While both promise the same core content and value...
The subject line featuring a number is FAR more tantalizing because it's crystal clear, specific, and implies that opening the email will arm you with 7 concrete tips to enhance your email open rates.
Strategy #4 – Sprinkle in Emojis (Sparingly)
I know emojis aren't everyone's cup of tea...
Personally, I'm a huge fan, and must consciously restrain myself from going overboard!
Emojis are fantastic for conveying a message, feeling or vibe without relying on words...
Even better, when used tastefully in subject lines, they can make your email pop in a crowded inbox.
Much like numerals, emojis disrupt the visual monotony, drawing the eye.
In fact, 56% of brands that include emojis in their email subject lines report higher open rates. (source: Campaign Monitor)
For example: " Sizzling summer deals inside! " ?"We've got BIG news "
However, there are a couple vital caveats to consider...
Firstly, it's all too easy to get emoji-happy ...
Not only can overuse be annoying, but it can also make you look spammy.
Aim to cap your subject line emojis at one. Even two can feel a tad much.
Secondly, always keep your audience's preferences in mind.
If emojis aren't on brand for you, over using them will likely erode your authenticity.
It could do more harm than good in the long term...
Just as we covered in Strategy #1...
NEVER betray your brand identity for the sake of a fleeting uptick in clicks. It's simply not a worthwhile tradeoff.
Strategy #5 – Embrace Brevity
Concise, punchy subject lines around 5-7 words long typically generate the best results.
That makes perfect sense when you factor in HOW most people are checking their email these days...
A whopping 81% of users access their inbox via mobile devices. (source: Zippia)
Meaning you're working with precious little real estate before your subject lines get mercilessly truncated...
On average, email subject lines between 61-70 characters are read the most at 17%.
Crafting a slam-dunk subject line becomes a real challenge, as you need to convey immense value and stir curiosity using a TINY word count.
Luckily, we're not restricted to just 7 words...
We can also harness the power of preheader text - the meta description of your email.
This is the snippet of preview text displayed right below the subject line.
Treat this as bonus space to expand on your subject line and amplify its impact.
My go-to approach is to write preheader text as a natural continuation of the subject line.
Used strategically, this hidden gem can work wonders for encouraging more opens and engagement.
For example: Subject: "Are you wearing the wrong size bra?" Preheader: "Take our 60-sec quiz for your PERFECT fit!"
Now, I'm not suggesting you cram all 5 strategies into a single subject line.
The key is to assess your core message and goals, then pick the most suitable tactic! Vary them across your email campaigns for maximum impact.
To bring this all to life, let's revisit the original subject line example from earlier...
"Improve Your Email Open Rates"
Applying the strategies we've covered, you could rework it as:
• Brand Voice: "Steal my sneaky tricks for crazy-high open rates"
• Asking a Question: "Are your subject lines falling flat? Fix it now"
• Using Numbers: "6 subject line formulas for sky-high open rates"• Leveraging Emojis: "Your secret weapon for inbox-busting opens "
And of course, all of your subject lines should adhere to Strategy #5 - keep 'em short, sweet, and under 7 words whenever possible.
For an extra edge, A/B test your subject lines on EVERY email! This is hands down THE most effective way to pinpoint what electrifies your unique audience.
To recap, the 5 proven strategies to skyrocket your email open rates are:
- Infuse your unique brand voice
- Pose intriguing questions
- Leverage the power of numbers
- Sprinkle in emojis (sparingly)
- Embrace brevity

FAQs:
Q: How can I identify my brand voice?
A: Your brand voice should reflect your company's unique personality, values, and the way you want to be perceived by your target audience. Consider your ideal customer and how you want to communicate with them. Is your tone casual and friendly, or more formal and authoritative? Do you aim to educate, entertain, or inspire? Answering these questions will help you shape a consistent brand voice that resonates with your audience. If you need expert guidance, Digital Marketing All offers tailored services to help you nail your brand identity.
Q: What's a good email open rate to aim for?
A: While average email open rates hover around 21% across industries, a "good" open rate largely depends on your specific niche and audience. At Digital Marketing All, we consistently achieve open rates between 25-50%. However, rather than fixating on an arbitrary number, focus on continuously improving your own open rates through split testing and refining your subject line strategies.

A: The optimal email frequency varies based on your industry, audience preferences, and the type of content you're sending. Some businesses do well with daily emails, while others see better engagement with weekly or bi-weekly sends.
