By leveraging our HAPI tag {@opt_out_url@} you can place a generated opt-out tag any where within your e-mail.
To take advantage of this, start by checking the "Remove the opt-out and company info from the bottom of my e-mail footer."

This will remove the standard opt-out footer from your e-mail, which you can now replace with a custom footer. Within this custom footer, you will need to add an "Opt-Out" link where the link is pointing to {@opt_out_url@}. When the e-mail is generated, it will automatically apply the link corresponding to the recipient and newsletter.
