$0.010
per message, in or out
PAYG
pay only what you use
Flat pricing, always: Twilio adds $0.003–0.010 in carrier surcharges on top of their base SMS rate. Kadeno's $0.010/msg is the total cost — inbound or outbound, every time.
What You Can Build
SMS automation patterns
- Outbound notifications — Appointment reminders, order confirmations, shipping alerts. POST to
/v1/sms/send with a number, message, and you're done.
- Two-way messaging — Inbound messages trigger a webhook to your server. Respond with JSON and Kadeno sends the reply. Build conversational SMS flows in any language.
- AI-driven auto-reply — Route inbound SMS to an AI endpoint. Your agent reads the message and responds. Same AI routing infrastructure as voice.
- Number-per-campaign — Assign different numbers to different campaigns. Track responses per number. Provision and release programmatically.
