Hi @d_G_n111 ,
Draft audience can be used in a journey and yes, they are evaluated by the evaluation job.
The major difference between draft and published audience is:
Draft audience is not finalised and is editable. You cannot reuse this audience in other journeys, it is limited to the journey where created. It exists in temporary state until published. Draft audience is best for one-time run journeys.
Published audience are finalised and is reusable across journeys.If you edit a published audience, you need to be careful about the impact, as it will change the eligible target audience for all journeys wherever audience is used from the next evaluation onwards. As a best practice, it is usually suggested to clone the existing published audience and then edit the audience. Published audience is used in multiple-journeys.
Thanks,
Pankaj
