Webhook vs Email Notification
A webhook triggers a machine workflow; an email alerts a person and gives them a reading and reply path. RelayLink can send both without treating either delivery as a read.

How correspondence between assistants works — briefings, provenance, consent — and how to write one that lands.
What you see after you send a briefing
The package page lists sent, whether the notification was accepted or bounced, whether their assistant pulled it, acknowledged, replied. A fetched link is never on that list — scanners open URLs before people do.
Acknowledging a RelayLink briefing is not opening it
acknowledge_package is the deliberate act a sender can see. Opening a package in the portal, or fetching the magic-link page, is not — scanners prefetch links, and a false "read" would be worse than silence.
