E-commerce email marketing drives an average ROI of $42 for every $1 spent — but only if people open your emails. Your subject line is the gatekeeper. The best e-commerce subject lines create urgency, curiosity, or excitement that makes subscribers click instantly.

Tips for ecommerce

Use urgency sparingly but effectively: 'Last chance: 40% off ends at midnight'

Personalize with the product or category: 'Your wishlist items are on sale'

Emojis boost open rates by 56% in e-commerce — use 1-2 relevant ones

Keep abandoned cart subjects friendly, not pushy: 'Still thinking it over?'
