"Unrestrictive Use"?

I’m a Free version newbie user. I’m very impressed with eM Client but wondered about the phrase, “unrestrictive use” under features for a Pro version license. Someone please clarify. Thanks!

A Free license has some restrictions; is not permitted for business use, can only have 2 email accounts configured, and has some features disabled. To see the difference between the licenses, please see this page.

Thanks for the quick response Gary. However, I saw that comparison and the other page that compared eM Client with competitors. It would appear the “unrestricted use” is a mere catch-all to include those additional features listed under the Pro version licensing. It is misleading or at least confusing in my view to include it and the company should consider deleting it or clarifying it.
