How do you get or post opt out links on emails?

I have a subscriber list and of course do not want to have any problems. If someone could help me, I would much appreciate it. Thanks

Sorry, I did not know how to start a new post. Hope this is ok


Here we go with another question for all. I have a list of subscribers on my gmail account. I wish to send an email to all at once. Of course 1 by 1 is a challenge. 1) can you with gmail list the individual name or does it have to be SUBSCRIBER 2) how can you email on To, cc, or bcc and not have the whole list of recipients showing.
Can anyone help me?
