Email Providers

All providers implement the MailProvider interface, giving you a consistent API regardless of which email service you use:

interface MailProvider {
  send(options: MailOptions): Promise<MailResponse>;
}

Choose the provider that best fits your infrastructure and swap between them without changing your application code.
