Hi Tanner,
Thanks for reaching out. Unfortunately, the Eventbrite email form previously added to Wordpress sites doesn’t work with the public API, so the email signup form on Wordpress will not be available moving forward. We recommend using a third-party email marketing service such as MailChimp for this which integrates directly with Eventbrite.
Please note this forum is for API Developers with questions related to working directly with the Eventbrite API. For support questions, it'd be best that you reach out to our Customer Support team: www.eventbrite.com/support/contact-us.
Best,
Donna
