Describe the difference between 'batch' and 'trigger' campaigns in Marketo.

Batch campaigns and trigger campaigns serve distinct purposes within Marketo, and understanding these differences is crucial for effective marketing automation.

Batch campaigns are specifically scheduled to run at predetermined times or intervals. This means that a set group of leads or contacts is targeted all at once, based on defined criteria. This can be useful for sending out newsletters, promotional emails, or any other mass communication where the timing is important, and the audience is predetermined.

In contrast, trigger campaigns are designed to respond immediately to specific actions taken by users. This means that when a lead or contact performs a defined action, such as clicking a link or filling out a form, they automatically enter the trigger campaign. This real-time response allows marketers to tailor their communications based on user behavior, leading to more timely and relevant engagement.

The effectiveness of each type of campaign can vary and does not necessarily pit one against the other, as both serve valuable roles in a comprehensive marketing strategy.
