The no-show problem, solved
Most no-shows are preventable. Here's what goes wrong β and how RelayBird fixes it.
Revenue slips quietly
Every missed meeting compounds into lost revenue and follow-up overhead for your whole team.
WhatsApp setup is heavy
Cloud API access usually means verification steps, number management, and template approvals.
Email alone is weak
Reminders that sit unread in an inbox still lead to missed sessions on both sides of the call.
No WhatsApp number needed
We send from our verified number on your behalf β you just connect Calendly.
Works in minutes
No Cloud API setup, no business verification, no template approvals.
Customizable reminders
Set multiple reminders per event β a day, an hour, or minutes before.
Three steps. Under five minutes.
No technical skills needed β RelayBird handles delivery once you set your preferences.
Sign up
Create an account with your email, or continue directly with your Calendly account.
Connect Calendly
One-click OAuth connection. RelayBird only reads the meetings it needs β nothing else.
Configure reminders
Choose when to send β a day, an hour, or minutes before β and who should receive them.
