use case
on-call notifications where the recipient picks the channel
reach on-call staff on the channel each one trusts — sms, push, whatsapp or voice — from a single broadcast, with per-channel delivery status.
the problem
on-call only works if the message gets through. one channel for everyone means whoever doesn’t live there misses the page.
how wupf solves it
each on-call person self-selects how they’re reached and verifies it once. you send one notification and wupf delivers it to each on their trusted channel, then shows you it landed.
the channel fit
sms and voice for hard-to-miss, push and whatsapp for the always-on. delivery status tells you who got it.
