How do I automate email on form submission?

Create a form, an email template, and an automation that connects them. The automation uses a form_submission trigger linked to your form and a send_email step that interpolates submitted data into the template.

Quick version: 1. POST /api/forms -- create your form 2. POST /api/email-templates -- create a template with {{placeholder}} syntax 3. POST /api/automations -- trigger type form_submission, step type send_email with templateId and to address 4. Submit the form -- the email sends automatically

This is more powerful than the simpler emailTo field on forms because you get custom templates, conditional logic, and can chain additional steps (like creating page entries or updating submissions) in the same pipeline.
