Tone: Value‑Focused and Motivating

Your Black Friday code just landed
This subject line triggers curiosity by making the discount feel personal and urgent. “Just landed” implies it’s hot off the press, which is perfect for inboxes flooded with generic sales spam.
I used the word “your” deliberately to give the impression that this code was meant only for the recipient.
It also dodges trigger words like “FREE” or “BUY” that spam filters sometimes flag around this season.

The rest of the sentence hits three core drivers: massive discount (70%), limited time (12 hours), and newness (“just dropped”). These numbers aren’t accidental either.
Deals above 50% convert faster on Black Friday. The line is short, punchy, and loud in all the right ways. Perfect for crowded inboxes on a sale day.

“For 3 hours” clearly states the time limit so that no one is left wondering.
Short words, zero fluff, and a cadence that ends on the clock—it’s exactly what late-night scrollers crave.

First, I start with the payoff: “45% off, because numbers jump out when people skim a crowded Cyber Monday inbox.

Then I stamp a crisp “4 PM” deadline to pull the strongest click-through rate. Setting a mid-day cut-off leverages that peak. Short, concrete, and benefit-first.
