What is a subscription?
A subscription brings several publications together, and for example, allows you to organize your documents according to subject (Michel's birthday, Project Briefing, etc.)
You can create as many subscriptions as you wish.
Only one of your subscriptions is set as the “Main” one. It’s the most important one and it can’t be deleted.
PREMIUM accounts can also manage their subscriber lists by subscription group, thus allowing for total subscription management for several different publications.
