When you purchase an eM Client Pro license it is valid for current official major version, all its updates and all older versions. You also receive one year of PRO support access. Our licenses do not expire, so there is no time limit on the program use.

Example: Current major version is eM Client 7. License purchased at this time will be valid for version 7.0, all its updates (7.1, 7.2, ...) and all older (6.0, 5.0, ...). The license key will always work with these versions.

When a new major version comes out there are few options on what you want to do with your license:

• Upgrade your license to use it with the new version 
• Purchase Lifetime upgrades to make your license valid for all future versions
• Pay nothing and keep using the older version as long as it works for you
