My 10 Highest Opened Subject Lines
Subject line is undoubtably one of the most important component of an email marketing campaign. Design, copy, content,… nothing matters if your subject line isn’t compelling enough to get your subscribers to open your email.
So, here’s my secret cheat-sheet for every time I need to boost the open rates for my clients. But be ware, over-using can lead to content-fatigue rendering these useless.
Checkout these subject-line guidelines that could make or break your relationship with your subscribers.
U up?
Don't Buy These Supplements From {Company}!
Is {your name/ company name} a liar?!
I need your help, {name}!
Your {subscription} is expiring
ACESS DENIED
Fwd: for
{NAME} Quick question?
Exposing fake {pill/ doctor} who promised {result}
Is {your company/ your name} a {fake/ liar}?
But before you start CTRL+C & CTRL+V to boost your open rates….
Click-baits only work if your content delivers on the promise.
Here's what separates successful email marketers from those who burn their lists:
The Golden Rule: Your subject line is a promise, not a trick. If you promise controversy, deliver insight. If you promise urgency, deliver value. If you promise a secret, deliver transformation.
The Reality Check: These subject lines work because they tap into psychological triggers - curiosity, FOMO, social proof, and controversy. But use them wrong, and you'll train your subscribers to ignore you faster than you can say "unsubscribe."
My 3-Step Verification Process:
Does it match my content? If your subject says "emergency" but your email is about a 10% discount, you're doing it wrong.
Would I open this from a stranger? If the answer is no, rethink it.
Can I deliver 10x the value I'm promising? If not, tone it down.
Pro Tip: Test these with small segments first. Track not just open rates, but click-through rates and unsubscribe rates. A 40% open rate means nothing if 20% of those people unsubscribe.
Remember, in email marketing, your reputation is your currency. Spend it wisely.
