Adobe Campaign offers a list of pre-configured content blocks. These content blocks are dynamic, personalized and have a specific rendering. For example, you can add a greeting or a link to the mirror page.
The images below show how to insert a content block using the Email Designer for an email.
The name of the content block appears in the editor and it is highlighted in yellow. It will automatically adapt to the profile when the personalization is generated.
The targeting dimension enables you to define in which type of message you can use the content block. This is to prevent using inappropriate blocks in a message, which may lead to errors.
Indeed, when editing a message, you can only select content blocks with a targeting dimension that is compatible with that message's targeting dimension.
For example, the Unsubscription link block's targeting dimension is Profiles because it contains personalization fields specific to the Profiles resource. Therefore, you cannot use an Unsubscription link block in an event transactional message, because the targeting dimension of that type of message is Real-time events . However, you can use the Unsubscription link block in a profile transactional message, because the targeting dimension of that type of message is Profiles. Finally, the Link to mirror page block does not have a targeting dimension, so you can use it in any message.
If you leave this field empty, the content block will be compatible with all messages, no matter what the targeting dimension is. If you set a targeting dimension, that block will only be compatible with messages that have the same targeting dimension.
