multi-channel broadcast features
one message, fanned out across email, telegram, push, slack, whatsapp, sms and voice — with the recipient, not the sender, choosing the channel.
the recipient picks the channel
the core inversion: instead of the sender deciding everyone gets an email, each person self-selects how they’re reached and verifies it once. you send one message; everyone gets it where they actually look.
one broadcast, seven channels
write once and fan it out across email, telegram, push, slack, whatsapp, sms and voice in a single send. no per-channel duplication, no copy-paste.
sms with zero a2p paperwork
wupf is the registered sender under a single platform a2p 10dlc registration, so your sms alerts need no ein, no carrier vetting, and no a2p forms. you stay in the operational-alerting lane; wupf handles compliance.
broadcast by email
every group has its own inbound address. email it from your approved sender and wupf turns it into a broadcast — no portal required.
per-channel delivery status
every broadcast shows a per-channel breakdown — sent, delivered, failed — so you know it landed, channel by channel and person by person.
passwordless, private by design
owners sign in with one-time email codes; subscribers use signed personal links. the group owner never sees a subscriber’s contact details — only their name and channel type.
