Guaranteed day-one reach
Upload the roster and reach 100% of people immediately. Reach is decoupled from app adoption — installing is an upgrade, not a requirement.
Reaches everyone on day one
Load your roster and your message lands on every device from day one — app, email, or web. No one left out. Nothing tied to personal numbers or personal chats.
No credit card. Set up your organization in minutes.
✕
Not a WhatsApp group
Owned by the org, not a personal account. Private numbers stay private. Compliant and audit-ready — no ads.
✓
Not the inbox they ignore
Push-first to installed devices, with email and web as guaranteed fallback — so the message actually gets seen.
Why Plenary
An intranet reimagined around one job: reaching everyone.
Restraint is the feature. Everything that doesn't help a message reach every person, reliably, is left out.
The org owns the channel
Never tied to a volunteer's or manager's personal account. People leave; the channel and its data stay. Full handover, export and control.
Managed identity
Staff and admins never expose personal mobile numbers to each other. Identity is verified email, not a phone number.
Compliance-ready by design
GDPR processor posture, DPA, EU hosting option, audit logs and retention control. No ads, no third-party data harvesting.
Proof it was seen
Read and acknowledgement tracking for safety-critical messages — so you know a shift change or alert actually landed.
No bloat
Not an inbox, not a filler dashboard, not a chat app. Communication-first is the filter every feature has to pass.
Pricing
Start free. Pay when reach becomes mission-critical.
Per active person, billed monthly. No per-message fees, no charge for people who only receive by email.
