价值前置，突出利益点直接告诉客户 “能得到什么好处”（降本、提效、合规等），戳中采购决策的核心诉求。✅ 好：CE-certified LED lights - 15% lower price than your current supplier❌ 差：LED Lights Supplier from China
简洁精炼，控制长度外贸客户日均收到上百封邮件，主题控制在 5-15 个单词，避免冗长，关键信息放前面。✅ 好：Quick quote: Customized packaging for your toys❌ 差：We are a professional manufacturer specialized in customized packaging for toy products and we can give you a quick quote
