Enterprise messaging
infrastructure for modern teams
Lynsms is a compliance-first SMS platform for product, marketing and security teams. Reliable global delivery, real-time analytics, and verified sender management — built for traffic you can defend.
Everything you need to ship messages safely
A complete toolkit for transactional, OTP and notification traffic — with the compliance layer enterprises require.
Global SMS delivery
Direct carrier connections across 200+ countries with intelligent fallback routing for high deliverability.
Real-time analytics
Live dashboards for delivery rate, latency and cost per route — exportable to your data warehouse.
Sender verification
Workflow for registering Sender IDs, alphanumeric senders and short codes with carrier-side approval status.
Traffic monitoring
Velocity tracking, duplicate detection and fraud scoring on every outbound batch — before it reaches the network.
REST API access
A single, predictable HTTP API with idempotency keys, paginated results and language-agnostic SDKs.
Webhook delivery
Signed webhooks for status updates, inbound messages and balance events with automatic retries.
Delivery reports
Per-message DLR with carrier-level reason codes and granular cost breakdowns for finance teams.
OTP messaging
Low-latency one-time password delivery on dedicated priority routes with rotation and replay protection.
Number validation
HLR lookup confirms portability, current carrier and roaming status before you spend a credit.
Rate limiting
Configurable rate ceilings per workspace, sender ID and destination country — with graceful queue behavior.
Fraud detection
Real-time scoring of suspicious links, spam keywords and unusual velocity patterns across every campaign.
Team access
Granular roles, scoped API keys and audit logs that map cleanly to your existing access model.
Know what's delivered, instantly.
Operational metrics shouldn't require a data engineer. Lynsms gives every team real-time visibility into delivery, latency and spend.
- Sub-second DLR ingestion — status reflected in dashboards within a second of carrier callback.
- Per-country and per-route breakdowns — identify failing operators before they impact campaigns.
- Exportable reports — CSV or programmatic access for billing and reconciliation.
Sender ID verification
Carrier-side review of every alphanumeric and short code sender before traffic is routed.
Spam and link scanning
Every payload is screened for known spam patterns, shortened URLs and prohibited keywords.
Velocity controls
Per-account and per-sender ceilings prevent runaway campaigns and protect carrier relationships.
Moderation queue
High-volume and high-risk campaigns are routed to human review with full transparency.
A platform built to keep your messages legitimate.
We invest in compliance so your sender reputation, carrier relationships and customer trust stay intact. Bad traffic is rejected before it ever reaches the network.

Common questions
What type of traffic is allowed on Lynsms?
We support transactional, OTP and consented marketing traffic. All campaigns must comply with our acceptable use policy and the destination country's regulations. New accounts begin with conservative limits and unlock additional capacity as we verify your traffic.
How does sender ID verification work?
You submit your sender ID through the console with supporting business documentation. Our compliance team reviews the request and registers it with carriers in the destination country. Status is visible in real time, and you can run pre-registration sample tests on non-restricted markets.
Do you offer dedicated short codes?
Yes. Short codes, long codes, and toll-free numbers are available on Scale and Enterprise plans for supported countries. Our team handles the carrier provisioning end-to-end.
How fast can I integrate?
Most teams send their first production message the same day they sign up. Our REST API uses standard auth and JSON payloads with detailed examples in every major language.
How do you handle GDPR and data residency?
Lynsms operates from EU regions by default with full GDPR compliance. We offer signed Data Processing Agreements, configurable retention, and EU-only routing for sensitive workloads.
