iNewsletter has a concept of publications. A publication is a way to group similar newsletters together. For example, you might have a community newsletter and a staff newsletter. These would be created as 2 separate publications, each with their own newsletter issues inside.
Each publication has its own name, privacy settings, subscribers and collaborators.
For education customers, you can create unlimited publications for the price advertised on our website. For business/non-profit customers, you will require a new subscription for each new publication you create.
