I have free version - where do I go to get the personal Pro?

I’ve looked in the menu/about - and there is no place I can find to upgrade from free to paid ?? Anyone can help? Also want to change my email address (as I am phasing out the one I was using) - again, can see no place to do this? Is there an EM client account sign on somewhere? Thanks in advance.

For your 1st question, you should buy a licence on Client’s website and then apply it in your eM Client app (Menu --> Help --> Licence --> Activate).

For the second question, purchase the Pro License using your new email address.

Thank you so much for both answers !
