Goodmorning, I’m wrinting you because EM client doesn’t allow to me to access to the mail address beacuse of there was a " license policy violation".
I try a new registration on your website in order to receive again the activation key ( 0370630b-2fbf-47c3-b63c-527ecb9e29cc), but unsuccessfully 
Can you help me?

best regards
Martina Bianco

A license violation means you are suspected of using a Free License for commercial or business use. If you are using it only for personal use, then you can write to eM Client and explain your usage and your license may be reinstated. If you are using it for business use, you need to purchase a Pro License.
