The subscription url is the web or email address potential subscribers use to subscribe. The subscription url is required.

This must be the full URL required to get your subscriber to exactly where they need to be to subscribe to your ezine. If it's a web address, it must begin with http://, and be the address of the form used to start a subscription. If it's an email address, it must begin with mailto:, and include required subject and body text as arguments. For example, if you have an ezine with a subscription email address of whiz-bang-ezine-request@nosuchhost.com, and your ezine software requires a subject with the word subscribe in it to subscribe someone, the correct URL would be mailto:whiz-bang-ezine-request@nosuchhost.com?subject=subscribe .
