make sure to read and understand:

... etc.

Note that many large providers have a local "reputation" base. so make
sure to get things "right" before trying anything (including testing).

Of course, I am assuming you only send mail to "confirmed" addresses
(the user replied that he wants your mail, and you kept the evidence).
If users subscribe by web and you send them a confirmation email, better
make this message neutral (it should not be confused with an advertizing
message). This also applies to "invite a friend..." and "send to a
friend..." applications.
