Email Systems
Measure email return and deliverability for the actual audience and attribution
window; no universal ROI or inbox-delivery guarantee applies.
This skill covers transactional email that works, marketing automation that
converts, deliverability that reaches inboxes, and the infrastructure decisions
that scale.

Example
For a password reset, enqueue a short-lived opaque reference, fetch the token
server-side without logging it, and deduplicate provider submission by event ID.
A timeout is an unknown send outcome: reconcile before resending; show the same
user-facing response whether or not the account exists.
