Per-recipient language. Message templates adapt automatically.
STOP/START opt-out
GDPR-grade opt-out keyword handling in 6 languages, tenant-wide.
Number mapping
Assign sender numbers per country and recipient for the best deliverability.

SMS alerts run on Cloudflare’s EU edge with GDPR opt-out and audit logging built in.
Compliance detailsSMS — frequently asked
Which provider sends the SMS?
Twilio today, via our provider abstraction. Telnyx and Vonage are on the roadmap for multi-provider routing and failover.
How are replies handled?
Inbound SMS hits a secure webhook; IRIS interprets “1” (acknowledge) / “2” (escalate) and updates the alert’s state machine, then logs it to the audit trail.
What does an SMS alert cost in credits?
Credits are priced at 1 credit = €0.01. A typical SMS alert costs a few to ~10 credits depending on destination country. Your 1,000 free trial credits cover roughly 100 alerts.
Is this GDPR-compliant?
Yes. Data resides on Cloudflare’s EU edge; we support GDPR Art. 15 export and Art. 17 erasure, STOP/START opt-out, and configurable retention. A DPA is available.
