超出预算通知
当您的广告活动达到预算时，您将会收到通知。
达到预算时，我们会向您发送一封电子邮件通知，告知您广告活动超出预算。对于每日预算，我们还会在广告活动管理中显示此通知。如果您选择增加预算，广告活动将继续显示给买家。对于每日预算，您的预算将会在次日进行重置，期间广告不会中断。
每日预算会被尽快花出，因为您的预算不是每天匀速用完的。这意味着，如果大量买家对您推广的商品感兴趣，则会在几分钟内花费较少的预算。
您的预算通知中的信息可能与您在广告活动管理中看到的信息不匹配。预算通知是账户提醒，而广告活动管理中显示的信息则反映了可能需要更多时间处理的广告活动报告。
注意： 当您收到通知时，请及时查看以确保已达到预算。如果达到了组合预算或商品推广总预算，您将需要调整这些上限以允许您的广告活动继续进行。

Out of budget notifications
Notifications are provided as your campaigns reach their budget.
When you reach your budget, we'll send you an email notification that a campaign is out of budget. For daily budgets, we'll also provide this notification in Campaign Manager. If you choose to, you can increase the budget and the campaign will continue to be shown to customers. For daily budgets your budget will reset at the start of the next day, at which point your ad will continue running.
Daily budgets are spent as quickly as possible and your budget will not be paced throughout the day. This means that a smaller budget could be spent in a few minutes if there are a large number of shoppers interested in your advertised products.
The information in your budget notification may not match what you see in Campaign Manager. Budget notifications are an account alert, while the information displayed in Campaign Manager reflects campaign reporting that may take additional time to process.
Note: When you receive a notification, check to make sure which budget has been reached. If a portfolio budget or Sponsored Products overall budget has been reached, you will need to adjust those caps to allow your campaigns to continue running.
