What type of program is used for an 'Email Send Newsletter' channel in Marketo?

An 'Email Send Newsletter' channel in Marketo utilizes an Email Program as it is specifically designed for sending out single email campaigns, such as newsletters. Email Programs allow marketers to create and execute email sends that can be targeted to specific segments of their database or to all leads within the system.

These programs support features essential for email campaigns, such as scheduling, defining recipients, tracking responses, and analyzing performance metrics like open rates and click-through rates. Email Programs are straightforward and work well for newsletters that are sent at regular intervals, making them a fitting choice for this particular use case.

While Event Programs are designed for managing registrations and communications related to an event, Engagement Programs focus on nurturing leads over time through a series of content streams. Adhoc Programs are typically used for one-off campaigns that may not follow the standard structure of an Email Program. In this context, the Email Program is the best fit for sending newsletters, which require focused execution and tracking.
