The quickest way to create an Audience is to start from Salesforce, on the Mailchimp Audiences tab. If you receive the error " You do not have the correct permissions to access Mailchimp," it is likely that:
- You are using their Standard, Essentials, or Free plan and have reached your audience limit. For instance the free plan allows only 1.
- You don't have the correct permissions on your Mailchimp user.
