Create and store a new email template on the Netcore CPaaS dashboard.

A template is a reusable server-side email layout referenced by template_id when sending emails.
You can include substitution placeholders like [% NAME %] that are replaced at send time.

Templates created in a master account are not accessible in subaccounts.
