"Bulk Mail" vs "Newsletter"

@Marc has asked me to post this: Admins have the ability to send "bulk mail", and members have the option of receiving "newsletters" - and apparently those are the same thing. If that is true then could we, please, make them one and the same?

As a new admin I didn't know that they are the same and had to ask for help figuring out how my members could opt in on receiving bulk mail. And with my memory I will probably forget that soon. So could we please make them the same?
