Your messaging stack, operated end to end.
Outsourced messaging operations: Flowstates owns the day-to-day running of vendors, routing, failover, monitoring, escalations and reporting across SMS, RCS, WhatsApp, email and voice. Want only the gateway infrastructure layer, or only a single API? Those are separate services.
Book a Messaging ReviewThe same view, sliced by destination country, vendor, business unit, channel or use case — so you can see exactly where delivery, latency or cost is moving.
Quick answer
Managed messaging means a provider operates your messaging gateway for you: routing, vendor contracts, failover, monitoring and delivery investigation. Flowstates runs SMS, RCS, WhatsApp and email traffic on your behalf under a 99.99% gateway SLA, while your team keeps its sender identities, customer data and business rules.
Your messaging data is scattered and blind
OTPs fail and nobody knows until a customer complains. Marketing messages go out across three vendors but you can't see how many times a customer was contacted today. Costs drift because there's no single view of what you're spending or how messages are being routed.
When a vendor goes down, your team scrambles to reroute manually — if they even notice in time. You're paying for infrastructure you can't see, can't optimise, and can't control.
No unified visibility
Customer interactions spread across vendors with no single view of delivery, failures, or contact frequency.
Uncontrolled costs
Multiple vendor contracts, no cost comparison, no route optimisation — you're overpaying without knowing it.
Manual failover
When a vendor goes down, your team has to reroute manually. Downtime means lost OTPs, missed notifications, and frustrated customers.
Telco-grade capabilities you can't build yourself
These aren't features bolted onto an API — they're built into our routing layer. The kind of capabilities you'd otherwise need a carrier relationship to access.
- 01
Automatic vendor failover
If a vendor goes down, traffic reroutes instantly to a backup — no outage, no manual intervention.
- 02
In-flight translation
Translate messages in real time as they're sent, without changing your application or templates.
- 03
Priority message sending
Mark critical messages (OTPs, alerts) as priority so they bypass standard queues and deliver faster.
- 04
Custom routing rules
Define routing logic per scenario — by message type, destination, time of day, or cost target.
- 05
Cost-optimised routing
We can provide routing ourselves to lower your per-message costs and reduce multi-vendor complexity.
- 06
Centralised visibility
See every OTP, notification, and marketing message across every vendor and channel in one place.

You keep commercial flexibility and vendor choice. We make it all work smoothly without you needing a telecom operations team.
Built-in tools to complete your stack
Beyond managed operations, our platform includes a multi-vendor OTP API and enterprise URL short link service, both fully integrated into your messaging layer.
Multi-vendor OTP API
Send one-time passcodes via SMS or email through a single API. Bring your own vendors or use ours; our platform handles routing, failover, and cost optimisation so your customers always receive their codes.
Multi-vendor failover
Route OTPs across multiple SMS and email vendors. If one fails, the next picks up automatically.
Single API, any vendor
One API call to send OTPs. We handle vendor selection, routing, and delivery behind the scenes.
SMS and email OTP
Send one-time passcodes via SMS or email through the same API. Add vendors without changing your integration.
Cost optimisation
Route OTPs through the most cost-effective vendor for each destination, reducing per-message spend automatically.
Enterprise URL short link service
Shorten, brand, and track every link in your messaging campaigns. Use our generic short domains or configure your own custom branded domains for a seamless customer experience.
Generic and custom domains
Use our shared short domains or set up your own branded custom domain for full control over your links.
Click analytics
Track clicks, geography, devices, and referrers across every short link in real time.
