Overview
The Email Kit delivers enterprise-grade email sending, covering multiple senders, tenant isolation, per-business template reuse, OSS-relayed attachments, retry on failure and full audit trails.
Personal config and platform config are physically separated: developers configure their own debug mailboxes; platform admins configure production senders; tenant admins configure tenant-scoped senders. Permission boundaries never overlap.
