Operate the existing comms stack — Mailgun transactional emails, Klaviyo profiles/segments, and Firebase test pushes for debugging.
Trigger / resend a transactional email to a single user — never bulk.
View a user's profile and segment membership (read-only).
Send a test push to a specific device for debugging — test targets only.
