Managed lines vs going direct to a provider
Both approaches are legitimate. This page compares what your team owns in each model, so you can decide based on your capacity — not on marketing.
What each model looks like
Direct provider approach
- Provider account and contract per vendor
- Number provisioning through provider consoles
- Provider-specific API and SDKs
- Provider-specific delivery events and formats
- Your own routing and fallback logic
- Support relationship per provider
- Your own monitoring and alerting
- Billing that varies by provider and route
SendiMessage approach
- Managed messaging line provisioned for you
- One public API for every workflow
- Unified message lifecycle (queued → delivered)
- Normalized, signed webhooks for delivery and replies
- Routing with iMessage where supported and SMS fallback
- Guided onboarding and one support path
- Per-line pricing plus usage
- Direct integration support during build-out
When direct is the better choice
Direct provider integration can be right for teams that need provider-specific features, negotiate their own carrier rates at very high volume, or already employ messaging specialists. If that's you, a well-chosen provider relationship is a strength — and SendiMessage is not always the best option.
When managed lines win
If messaging is a feature of your product rather than your product, the managed model converts an operations problem into an API call. The comparison to run is honest: your engineering hours on messaging infrastructure versus per-line pricing — the complexity tool below helps you inventory the first half.
