If you are using Email Marketing and would like to display a signup form for a specific campaign on a page, the Campaign Signup form shortcode will provide that for you. This shortcode has one option:
- Campaign ID: This present on the URL of the Edit Email Campaign page. The number that appears after a= is the campagin ID.
This will display an email address input field, a submit button, and one of two disclaimers depending on your Form Opt-In Type setting.
