What types of campaigns can be executed in Marketo?

The correct choice highlights the types of campaigns that can effectively be executed using Marketo. Email campaigns are a primary feature of Marketo, allowing for targeted communication with leads through personalized content and automation. Social media campaigns can also be integrated within Marketo to enhance engagement across platforms and leverage social channels for lead generation and nurturing. Event campaigns involve the ability to manage and promote events, track attendee engagement, and follow up with participants, which is a critical aspect of marketing automation.

The other choices, while they include elements of marketing, do not encapsulate the core functionalities and capabilities of Marketo as focused on in this context. For example, print campaigns do not leverage Marketo's digital-first approach, and cold calls or telemarketing are outside the scope of the platform’s main focus on digital marketing and automation. Webinars can be part of a broader event strategy, but the correct selection emphasizes the integration of multiple channels, particularly those that Marketo is designed to enhance.
