Mess up these 40 characters of copy and you’re cooked.

🚀

You could write the best email in the world.

Make micro adjustments to every line until it’s a masterpiece.

Then finish off with a perfect cutthroat CTA.

But guess what?

If no one opens it… it’s worthless.

That’s why the 40 characters that you put in the subject line have to be spot on.

Filled with curiosity, urgency, or even just a crazy pattern interrupt.

This is important because the subject line is the gatekeeper of your email.

And most inboxes only show those first 40 characters.

No open = no click = no sale.

So, never, ever, ever treat subject lines like an afterthought.

Many copywriters would say they’re the most important part…

But I’d argue this and say they are everything.

Without a killer subject line… the rest is pointless because it’ll never get seen.

So, here’s a challenge for you:

Go read your last 5 subject lines.

Would you open them?

If not. Rewrite them.

Prof. 4D.
