向买家发送重要消息
在【联系买家】页面上，您只能根据订单状态和特定商品分类选择部分联系原因。
如果是必须发送消息才能完成订单，亚马逊不会屏蔽这些消息。如果您的消息被屏蔽，原因是买家选择不接收卖家发送的非关键消息，或者亚马逊将所选的联系原因视为对完成订单并不重要。
要发送与特定订单相关的消息，请在卖家平台中执行以下步骤：
转至【订单】菜单，选择【管理订单】。
找到您要联系的买家所下的订单。
在【订单详情】列中，点击买家姓名，打开【联系买家】页面。
在下一页上，选择联系原因，填写消息，然后点击【发送】
重要： 您将无法编辑从卖家平台发送的电子邮件的主题行。亚马逊将发送与完成订单相关的消息。
要发送与特定订单相关的消息，请使用您的电子邮件客户端，执行以下步骤。
在主题行的任意位置，添加使用方括号的[重要] (Important) 一词。该电子邮件将不会被屏蔽，您也不会收到退信邮件。
注意： “重要”(Important) 一词大小写都可以使用，但必须包含在方括号内才有效。例如，主题行“需要更多信息”应改为“[重要] 需要更多信息”或“需要更多信息 [重要]”。
重要： 对不重要的消息使用 [重要] 可能会导致您的销售权限被暂停。 如果您使用其他主题，消息将被退回（如果买家选择不接收所有卖家主动发送的消息）。买家也可以将消息标记为不当消息。因此，消息内容应仅限于索要完成订单所必需的信息。

Send a critical message to a buyer
On the Contact Buyer page, certain contact reasons are available for you to select based on the order status and specific product categories.
Amazon does not block messages if they are necessary for completing an order. If your message was blocked, it is due to the buyer opting out of non-critical messages from sellers or Amazon treats the selected contact reason as one that is not critical for completing the order.
To send a message related to a specific order, follow these steps in Seller Central:
Go to the Orders menu, select Manage Orders.
Locate the order that you want to contact the buyer about.
In the Order Details column, click the name of the buyer to open the Contact Buyer page.
On the next page, select a contact reason, complete the message, and click Send
Important: You will not be able to edit the subject line of the emails sent from Seller Central. Amazon will deliver the messages related to completing an order.
To send a message related to a specific order, follow these steps using your email client.
Include the word [Important], with brackets as shown, anywhere in the subject line. The email will not be blocked and you won't receive a bounce back message.
Note: You can use capital or lowercase letters, but the word important must be surrounded by brackets to be effective. For example, the subject line "Need additional information" should instead be "[Important] Need additional information" or "Need additional information [Important]."
Important: Use of [Important] for non-critical messages may result in the suspension of your selling privileges. If you use other subjects, the message will be bounced back if the buyer has opted out. Buyers can also flag messages as inappropriate. Therefore, the content of your messages should be limited to requesting only the information you absolutely need to complete an order.
