Licence
A PrimeMail licence covers one WordPress installation. You may install it on a staging copy of that site at no extra cost.
Updates and support
A licence includes plugin updates and support for the period stated at purchase. PrimeMail keeps working after that period; it simply stops receiving updates until the licence is renewed.
