Yeh, simply find the member or members you wish to mail through the "Member Management" screen and then at the bottom of the list you'll see a dropdown that will allow you to email members (as well as a few other functions); it'll allow you to email users or export a list of email addreses for you to use a 3rd party script to send mails out.
I'm not sure what version the trial is based off of but I doubt it's in the 6.7.x series.
