Must I continue to use eM Pro in order to use my 3 Google e-mail accounts that I have in addition to my 2 Comcast email accounts?

Am using eM Client Pro for 30-day trial and am hugely impressed. One question re: adding Google accounts now. In the event that I decide to go instead with the Free version (non-commercial, 1 computer) will my 3 Google accounts end up being counted towards the limit of only 2 accounts which Free version users are otherwise limited to?

Yes, if you want to use all your mail accounts you have to purchase eM Client PRO.
