When a client subscribes or unsubscribes to your Email Marketing System, they can be directed to a custom page of your creation.
To do so, you’ll want to start by logging into your client portal.
From here click on Email Marketing System.
You’ll be brought to your Email Marketing System and at the top there will be a menu, you want to click on the item that says Lists.
You will then see all your Email Marketing Campaigns and the number of contacts subscribed to each. You want to click on the name of the campaign, in this example we are just going to use the monthly newsletter, so click on Newsletter.
On the next screen you will be presented with a lot of information, but we only really care about what is on the left and the two highlighted fields, the subscribe and unsubscribe fields.
You can enter any page on your site you want. For instance:
