Advanced permissions have been added to Postmark, allowing users to create Account Admins and Server Admins, which grant varying levels of access to account information and servers. This change enables multiple people to work on different accounts and servers, addressing issues for larger companies. The new feature also includes the ability to add additional email addresses for billing notifications and a redesigned Users area with filtering and role assignment options. Two-factor authentication is in development and expected to be released early in 2018.
