    The operations layer for business-critical messaging

    One operations layer for every vendor and channel you send through.

    Flowstates runs the routing, failover, monitoring and vendor escalations behind your SMS, RCS, WhatsApp, OTP, email and voice traffic. Bring your own vendors, use ours, or mix — your stack stays yours; we operate it.

    SMS gateway, CPaaS, messaging APIs & OTP — one platform

    Some teams need high-volume routing and vendor control. Others need journeys, APIs or a better way for customer-facing staff to manage ongoing conversations. Flowstates brings these together in one platform and one operating model.

    Managed Messaging Operations

    End-to-end operations for high-volume SMS, RCS and WhatsApp traffic — vendor management, multi-vendor routing, failover, monitoring, escalations and unified reporting under one SLA.

    Multi-vendor SMS routing: BYOV, Flowstates routes, or hybrid

    Flowstates supports BYOV, Flowstates routes and hybrid deployments. That means you can protect existing commercial relationships, add new routes where needed and avoid rebuilding your stack when your requirements change.

    BYOV

    Keep your current messaging providers and let Flowstates run the operational layer across routing, monitoring, failover and vendor coordination.

    Flowstates routes

    Use Flowstates routes when you want a simpler operating model, better resilience or more control over performance and support.

    Hybrid

    Use strategic existing vendors where they make sense and add Flowstates routing or custom routes where you need more flexibility.

    Avoid CPaaS lock-in without building in-house telecom ops

    The usual trade-off in messaging is simple: buy a single platform and accept the limits, or manage multiple vendors and absorb the complexity yourself. Flowstates gives you a third option — more control than a single-provider setup, without building a telecom operations function in-house.

    More flexibility

    Bring your own vendors, use Flowstates routes or blend both without rewriting your whole stack.

    More operational ownership

    Flowstates helps run the messaging layer day to day, including monitoring, escalations, route changes and issue handling.

    More visibility

    Get a clearer view of performance, routing, delivery and messaging activity across channels, vendors and regions.

    More room to grow

    Start with gateway operations or APIs, then expand into journeys, URL short links or relationship-led conversation workflows.
