请确保您电子邮件程序的垃圾邮件过滤器不会屏蔽买家消息。
即使您无法立即解决买家的问题，您仍需在 24 小时内回复电子邮件，告诉买家您正在处理他们的请求。提供一个预计问题能够得到解决的日期。

Respond to messages
Respond to buyer messages within 24 hours, including weekends and holidays. Auto-responders are not considered a valid response.
If your message response time is affecting your overall seller performance, the following suggestions may help ensure that you respond to buyer messages within 24 hours:
Make sure that buyer messages are not being blocked by your email program's spam filter.
Even if you can't resolve a buyer's concern immediately, you still need to respond to their email within 24 hours to let them know you are investigating their request. Provide a date by which they can expect a resolution.
If a message does not require a response (for example, a "thank you" message), then make sure you mark it as "No Response Required."
