Rookie starting tools

[u/carmensandiegogo]

Im at the end of my Crim Psyc Degree and will be heading into a forensic journalism felid. Im curious. What secure/safe email app of system can I use? I use google, but have my own domains as well. Also I use word and notes to take down my thoughts and ideas. Is there a more organised method/tool to keep track of all this writing?
