One API. Any Provider.
Your Rules.

Stop managing multiple messaging providers. OneSend2U gives you a single API to send SMS, Email, and WhatsApp through any provider — with configurable provider routing, cost visibility, and zero vendor lock-in. New channels coming soon!

// Send via any provider with one call
POST /api/notifications
{
  "channel": "sms",
  "to": "+5511999999999",
  "template": "order_confirm",
  "variables": { "orderId": "12345" }
}
POST /api/notifications
{ "channel": "sms", "to": "+55..." }

The messaging integration problem

Locked into one provider? You face downtime risk and zero negotiation leverage. Using multiple providers? You maintain separate integrations for each one, and switching means changing every application. Either way, you lose.

Vendor lock-in

Switching providers means rewriting integrations, re-testing templates, and weeks of migration effort. You stay because leaving is too expensive.

No failover

When your single provider goes down, your messages stop. No automatic failover, no backup route — just downtime and lost revenue.

Cost opacity

Provider invoices are cryptic. You cannot tell what each message actually costs, which channels are profitable, or where budget is being wasted.

Integration sprawl

Each provider has its own SDK, webhook format, and error codes. Your team builds and maintains a separate integration for every provider you use.

Switching cost

Want to change providers? You have to update every application that uses the old integration. The more apps you have, the more painful — and risky — the migration becomes.

Slow time to market

Building messaging from scratch takes weeks. Every new channel or provider means another integration project, slowing down your product launches.

How it works

One integration. Multiple providers. Automatic routing and cost visibility across every channel you use.

Send through any provider

Integrate once with the OneSend2U API. We route your SMS, Email, and WhatsApp messages through Twilio, Infobip, SendGrid, SMTP, or any configured provider — without changing a single line of your code.

Provider routing

Define routing rules per country, channel, and notification type. Set primary and fallback providers and switch providers at runtime — no redeployment required.

See what you actually pay

Track costs by provider, channel, country, and application. When providers report per-message pricing, you see it automatically. Full visibility into your communication spend.

Built for enterprise

A modern, event-driven architecture designed for reliability and scalability from day one.
