老客户突然没消息了，怎么跟进

✅ 1. 常规询问版

Hope you're doing well. I haven't heard from you since my last message. I just wanted to check in and see if everything is okay on your end. Please let me know if there's anything I can assist with. 希望您一切顺利。上次联系后一直没收到您的回复，所以想跟进了解一下您这边是否一切都好？如有任何需要协助的地方，请随时告知。

✅ 2. 释放善意版

Just reaching out to say I'm still here for you. No pressure at all. If you're busy or your plans have changed, just give me a quick heads-up so I know where we stand. Appreciate it! 只是跟您打声招呼，我这边一直都在。没有任何催促的意思。如果您在忙或者计划有变，方便时简单告诉我一声，让我心里有个数就好。多谢啦！

✅ 3. 提供价值版

I understand you might be busy. To save your time, I've updated the quotation for our regular items with our latest best offer attached. If it's not a good time, just ignore this. No worries. 知道您可能很忙。为节省您时间，我已更新我们常订产品的最新最优报价，并附在邮件中。如果时机不合适，忽略此邮件即可，没关系。
