What are the two types of smart campaigns in Marketo?

In Marketo, the two types of smart campaigns are indeed characterized as Batch and Trigger campaigns.

Batch campaigns are designed to run at scheduled times, processing a list of leads all at once. These campaigns allow marketers to execute tasks such as sending emails, updating lead information, or applying tags based on a pre-defined set of criteria. A batch campaign can be set to run periodically, such as daily or weekly, to engage leads based on specific data conditions.

Trigger campaigns, on the other hand, are dynamic and react to real-time actions taken by leads. These campaigns are set to initiate automatically when a lead performs a specific action or meets specific criteria, such as filling out a form, clicking a link, or changing their status. Trigger campaigns enable marketers to respond immediately to lead behavior, making them a critical tool for timely engagement.

The other options mention types that do not accurately reflect the standard definitions used in Marketo. Recurring and default do not correspond to the way campaigns are structured within the platform, and "smart" is more of a descriptor rather than a type of campaign. Understanding the distinction between these two types of campaigns is essential for effectively using Marketo to manage marketing automation and provide timely, relevant interactions with leads.
