What makes these work
Discount-subject lines are the most over-saturated category in email. The patterns that still earn opens lead with specificity rather than percentages: 'Three things on sale this week' beats '50% OFF EVERYTHING'. Stating the exact percentage and the exact deadline up front is more effective than vague urgency. Avoid ALL CAPS and excessive exclamation points; spam filters now down-rank these subjects, and recipient pattern recognition has caught up to them. For high-AOV brands, the best discount subjects often pair the offer with brand-voice continuity ('A spring sale — picked by hand') so the email feels like a curated note rather than a blast.
