Subscription / Un-Subscription forms can be integrated with your website, microsite or landing pages. To create new subscription / unsubscription forms for your mailing list(s) follow the steps below.
The options tab will allow you to select more mailing lists so that when a subscriber subscribes using this form they will also be subscribed to selected lists under options.
You can also choose to include custom fields associated with the mailing list you are generating the subscription form.
Click on the "Unsubscription Form" tab and you should see the html code, copy and paste the html code within your website and customize the html code as you want but you must not change the action of the form or the name of form elements.
