Stop writing clever subject lines. Clever gets you ignored. The formula that doubled our open rate is stupidly simple: four words, one specific number, zero adjectives. Compare this. New collection just dropped versus The 3 jackets that survived testing. The first is wallpaper. The second is a story with a number in it. Specificity signals that the email contains real information, not just promotion. We tested this across sixty thousand emails. Specific beats clever every single time. And when you doubt it, remember: your subscriber deletes twenty emails a day. Be the one that sounds like news, not like marketing.
