Hey,
Quick truth most marketers don’t like hearing:
If an email doesn’t get opened, the rest of the copy doesn’t matter.
Not the offer. Not the CTA. Not the clever closing line.
The subject line makes the call.
And most people…
guess.
They write one line, cross their fingers, and hope today’s the day the algorithm is feeling generous.
That’s backwards. The best marketers don’t guess—they work angles.
So I built something to make that easy.
It’s called Subject Line Engine.
It’s a free custom GPT that:
– Reads your email
– Identifies the psychological angles that actually fit
– Generates multiple subject line options instead of one
Hail Mary attempt
No clickbait. No spammy tricks. No “AI-sounding” nonsense.
Just
subject lines that feel human and earn the open.
If you send emails (promos, newsletters, launches, anything), this saves time and improves results.
You can grab access here:
👉 Get Subject Line Engine
Paste in an email you’ve already written and try it. You’ll immediately see why most subject lines fail—and what to do instead.
