One event, four channels. A template is written per event and per channel, because what reads well as a push line does not work as a WhatsApp template — and WhatsApp templates must be approved by Meta before they can be sent outside the 24-hour window.

Channel fallback

What happens when the first choice does not land
Try push first
Free, instant, and it opens the right screen in the app
No device token, or not delivered in 5 min
Fall through to WhatsApp, if a template is approved for this event
WhatsApp undelivered in 30 min
Fall through to SMS, where the event allows it
Still nothing
Email, and a task on the owner's queue to phone the candidate
Fallback is per event, not global. A deployment update chases hard; a marketing message does not chase at all.
