在此页面上：了解如何使用反应活动响应消息跟踪数据（如同一历程中的打开数和点击数），并为未参与的个人配置超时路径。
概述 overview
在面板中可用的不同事件活动中，您会找到内置的 反应 事件。 您可以通过此活动，对在同一历程中与所发送消息相关的跟踪数据做出反应。 我们在与 Adobe Experience Platform 共享时实时捕获此信息。
您可以对单击或打开的消息做出反应。 例如，如果某人打开了之前的电子邮件或单击了其中的内容，则您可以发送另一封邮件；如果某人未参与您的通信，则您可以发送另一封后续邮件。
查看操作活动。
如果没有对您的消息做出反应，您可以使用 反应 活动执行操作。 为此，请创建与 反应 活动平行的第二个路径，并添加 等待 活动。 如果在 等待 活动中定义的时段内没有反应，将选择第二个路径。 例如，您可以选择发送跟进消息。
如何配置反应事件 configure
按照以下步骤配置反应事件：
护栏和限制 guardrails-limitations
- 必须在历程画布中的渠道操作活动之后 立即 放置 反应 活动。
- 如果之前没有渠道操作活动，则不能使用 反应 活动。
- 不支持在渠道操作与 反应 活动之间放置 等待 活动或任何其他活动，这可能会导致反应无法按预期运行。
- 反应事件只能跟踪在同一历程中发送的消息。 它们无法跟踪在其他历程中发生的消息。
- 反应事件跟踪“已跟踪”类型链接的点击次数。 也会考虑取消订阅链接的点击次数，并触发 电子邮件点击 反应事件。 不考虑镜像页面链接。
- 使用电子邮件中包含的0像素图像跟踪电子邮件打开次数。 如果电子邮件客户端（如Gmail）阻止图像，则不会考虑电子邮件打开次数。
This section contains structured knowledge intended to support interpretation, retrieval, and question answering related to this topic.
For complete understanding, this information should be combined with the documentation on this page. Neither source is intended to stand alone; the page describes the feature, while this section provides additional context that helps disambiguate terminology, intent, applicability, and constraints.
- TL;DR: This page explains how to use the built-in Reaction event activity in Adobe Journey Optimizer to branch journey paths based on real-time message engagement data such as email opens and link clicks.
Intents:
- Add a Reaction event activity to respond to message opens or clicks within a journey
- Configure an event timeout and timeout path for individuals who do not react within the defined duration
- Create a parallel path with a Wait activity to handle non-responders
- Select an action activity from an earlier step in the path to react to
Glossary:
- Reaction event: A built-in journey event activity that listens to real-time tracking data (opens, clicks) from a message sent earlier in the same journey (product-specific)
- Timeout path: A second path for individuals who did not react within the defined duration (product-specific)
Guardrails:
- A Reaction activity must be placed immediately after a channel action activity. Placing a Wait activity or any other activity between the channel action and the Reaction activity is not supported and may result in the Reaction not working as expected.
- A Reaction activity cannot be used if there is no channel action activity before it in the path.
- Reaction events can only track messages sent within the same journey; cross-journey tracking is not supported.
- Reaction events track clicks on links of the type “tracked”. Clicks on unsubscription links are also taken into account and trigger an Email Click reaction event. Mirror page links are not taken into account.
- Email opens rely on a 0-pixel tracking image; if the email client blocks images (e.g., Gmail), opens will not be recorded.
- You can define an event timeout between 40 seconds and 90 days, and a timeout path. In test mode, Wait time has a default and minimum value of 40 seconds.
Terminology:
- The built-in event in the palette is Reactions; the activity is Reaction.
FAQ:
- Q: Can a Reaction event track a message sent in a different journey? — No; reaction events only track messages sent within the same journey.
- Q: How do I handle individuals who do not open or click a message? — Add a parallel path alongside the Reaction activity with a Wait activity; individuals who do not react within the wait duration will follow that second path.
- Q: Are unsubscribe link clicks tracked by reaction events? — Yes; clicks on unsubscription links trigger an Email Click reaction event. Mirror page links are not taken into account.
- Q: What happens if an email client blocks images? — Email opens tracked via the 0-pixel image will not be recorded for clients that block images, such as Gmail.
- Q: What is the valid timeout range for a reaction event? — Between 40 seconds and 90 days.
