Should I use emoji in abandonment email subject lines?

As an e-commerce store owner, I've been wrestling with email marketing optimization, and emojis have become this mysterious strategy I can't quite crack. My abandonment emails are technically solid—great copy, compelling offers—but my open rates are frustratingly inconsistent. I've heard mixed advice about using emojis: some say they're playful and attention-grabbing, while others argue they look unprofessional. My target audience is primarily millennials and Gen Z in the fashion and beauty space, so I'm wondering if emojis might actually help me stand out in a crowded inbox. My current abandonment email subject lines feel bland, and I'm desperate to find a strategy that increases my recovery rate. I've tried A/B testing different approaches, but I need a definitive answer on whether these tiny digital icons can genuinely improve my email performance. More importantly, I want to understand the psychology behind emoji usage—are they a genuine engagement tool or just a passing trend? With my margins getting tighter and customer acquisition costs rising, every percentage point of email performance matters.
