Thank you for your reply.
I will be using Campaign from January next year.
However, I have no knowledge of Campaign, so I don't know what I can do.
I have vague concerns.
Experience League is our portal where you can find all the learning content - courses, documentations, how-to tutorials, and instructor-led trainings, related to Adobe Campaign: https://experienceleague.adobe.com/
You will also be able to get personalized recommendations based on your role, experience level, and industry after creating and completing your profile on this portal.
If you have questions related to any of the Experience League content, you can post them here on the Community and we will have our experts answer your concerns.
Hope this helps.
