Need clarification on what is meany by "accounts"

I have a Gmail and a Hotmal address. I also have several sbcglobal.net and att.net addresses in addition to a fastmail.fm address. I also have several systems at home and one at work.

  1. Can I install on more than one system or do I need either a free or purchased registration to use on more than one.
  2. Am I correct in assuming that a single email address is considered an “account” and since I have several, I would need the pro version?
    Thanx,
    Vic

You cannot install on more than one machine with a single license.  Yes, accounts are email accounts you have set up in eM Client.  Looks like you will need a pro license.

So a pro license for each system would be required.

ok - Thanx!
