You should purchase a license that is equivalent to the number of mailboxes or users protected by GFI MailEssentials.

GFI MailEssentials 21 and later provides two licensing options:

  • Legacy licensing: Enter a valid license key in the product's user interface
  • Subscription licensing: Use a GFI Account that has a license for GFI MailEssentials. This method automatically synchronizes your license key with GFI Accounts.
