Admin roles & email notifications in CodeTwo Email Signatures for Office 365

There are three admin roles in CodeTwo Email Signatures 365:

  • Owner in CodeTwo Admin Panel can manage organization’s billing information, admins, tenants and subscriptions. A user that first creates a CodeTwo Admin Panel account for an organization automatically becomes the owner of that account. An organization can only have one owner in the CodeTwo Admin Panel, but the owner can transfer ownership to another admin (learn how to do so). An owner can use either Microsoft account or Email and password to sign in to CodeTwo Admin Panel; however, using the former is required to manage Admin Panel admins. Learn more about account types in CodeTwo Admin Panel
  • Admins in CodeTwo Admin Panel can manage organization’s tenants, subscriptions and signature rule admins. An admin needs to use the Microsoft account sign-in type when signing in to the CodeTwo Admin Panel. An organization can have multiple admins in the CodeTwo Admin Panel, and these admins are managed by the owner (learn how to invite admins). Admin Panel admins need to use the Microsoft account to sign in to CodeTwo Admin Panel.
  • Signature rule admins can access the signature management app to create organization-wide signature and autoresponder rules, as well as design templates to use with them. Learn how to manage signature rule admins

In addition, all Microsoft 365 global admins can manage tenant settings, email signatures and signature rule admins. They don't need to have an Admin Panel account or be assigned any of the CodeTwo Admin Panel roles. Read on for details.

Who gets email notifications about CodeTwo services

There are three types of email notifications sent from CodeTwo Email Signatures 365:

  • Billing information (invoices) are sent to the Contact email address of the Admin Panel owner, specified on the Contact info page (learn more).
  • Notifications regarding an Admin Panel account (e.g. email address confirmation or password change) are sent to the email address used to sign in to the CodeTwo Admin Panel. This means the owner and all admins will get notification regarding changes made to their Admin Panel accounts.
  • Notifications regarding tenants or about CodeTwo service health are sent to the Contact email address and the sign-in email address of the Admin Panel owner and all admins. They are also sent to the email address of a Microsoft 365 global admin if their credentials were used to register a tenant to the CodeTwo service.
