mailing list / Newsletter

Hello,

I want to create a simple mailing list or newsletter but I have problems with requesting email...
Situation:
form.html:
form action="send.php" id="1" method="POST">
input type="checkbox" name="email0" value="email_one@mydomain.com">
input type="checkbox" name="email1" value="email_two@mydomain.com">
input type="checkbox" name="email2" value="email_three@mydomain.com">

input type="submit" value="SUBmIT">
/form>
-----------------------------
send.php:
I want to $_REQUEST email array separately so I can send mails separately - to each email its own email ..

Can somebody help? Thanks
