Configuration

Resend Utils reads the Email section from appsettings.json when AddResendEmail receives an IConfiguration instance. The section is bound to EmailSettings and is used to configure the Resend API token, sender identity, brand values, footer text, and reusable template placeholders.

The Email section is required during startup registration. If the section is missing, AddResendEmail throws an InvalidOperationException before any email services are registered, so configuration mistakes fail early instead of surfacing later when the application tries to send an email.
