If I buy the licence is necessary pay this amount every year or is sufficent pay just one time/una tantum?

thank you

Hi Dimi, eM Client’s PRO license is a one time purchase, the difference though is between purchasing eM client’s single license or with “lifetime upgrades” included.
Purchasing the application with lifetime upgrades, will guarantee you access to all future releases, where as the single license without lifetime upgrades only entitles you to updates for the current release (6).

Hope this helps,

thank you so much Paul !!
