If you are unsure which program type to use, which option serves as the catch-all in Marketo?

The default program serves as the catch-all in Marketo because it is designed to accommodate a wide variety of marketing initiatives when the specific nature of the program is unclear. This program type provides flexibility and broad functionality, allowing marketers to organize assets and campaigns that do not fit neatly into other program types like email, events, or engagement programs.

Using a default program, you can incorporate various marketing tactics, including emails, landing pages, and assets, without the restrictions that are typically tied to specific program types. This adaptability makes it an ideal choice when there's uncertainty about the most suitable program framework to employ for a particular campaign or initiative.

The other program types have more defined purposes and criteria for use. For example, email programs are specifically targeted at managing email campaigns, event programs are for live or virtual events, and engagement programs are designed for ongoing communication with leads based on their behavior and stage in the buyer's journey. Therefore, when in doubt, the default program is the appropriate choice to ensure that all marketing activities are effectively tracked and managed.
