New user: Best strategy to get a licence to version 10

Since Microsoft introduced their “New Outlook” spyware, I have been looking around for an alternative and eMClient has caught my eyes.
However I don’t want to buy a license for version 9 since version 10 is in beta.and I won’t be able to update to that version.
So what is the best strategy to make sure that I get a license to version 10.
Should I install the beta version? I read it’s time limited and I’m worried it will stop working before version 10 is released.

What is your advice on this matter?

The beta is time limited and will cease to function a few months after the official version 10 release.
