What it does
Notification delivery checklist
5 of 8 confirmed in ntfy's own documentation. The same checklist is used for every tool in Notifications.
- Mobile push Yes
- SMS Not confirmed
- Voice calls Yes
- Email Yes
- Chat apps Not confirmed
- HTTP API or webhook ingest Yes
- Bypass silent mode Yes
- Acknowledgement Not confirmed
Phone calls and email forwarding need a verified account on ntfy.sh (or config when self-hosted). Android notification channels can override Do Not Disturb. Action buttons can call URLs, but no built-in acknowledge.
Checked against: docs.ntfy.sh, docs.ntfy.sh (2), docs.ntfy.sh (3), github.com
