3 tips for e-commerce email subject line generator
📬 The curiosity gap works for E-commerce emails
The most opened e-commerce email subject lines create an information gap that can only be closed by opening the email. Instead of "New e-commerce tips this week", try "The e-commerce mistake costing online shopperss thousands". The brain's need for closure compels the open — consistently delivering 40–60% higher open rates for e-commerce email lists.
📱 Optimise for mobile — where e-commerce emails are opened
Over 70% of e-commerce emails are opened on mobile, where subject lines truncate at ~40 characters. Your e-commerce email's most important words must come first. "3 product launches secrets" beats "Everything you need to know about product launches in 2026" for mobile-first online shoppers audiences. Generate multiple length variations and test both.
🧪 A/B test e-commerce subject lines every send
Most email platforms let you A/B test two subject lines. For e-commerce email lists, test one element at a time: curiosity vs. specificity, question vs. statement, emoji vs. no emoji. E-commerce brands that consistently test subject lines see 20–35% better open rates within 90 days compared to those using a single variant.
