PLATFORM ARCHITECTURE
High-throughput A2P message switching with complete routing sovereignty
TextEnvoy is an independent A2P SMS switch designed for providers who demand direct control over their messaging traffic. Ingest traffic via standard SMPP or modern REST APIs, enforce client credit quotas in real time, and terminate across your own upstream supplier binds with zero middleman interference.
SMPP v3.4 Server Bind • RESTful HTTP Sending API • Supplier SMPP Binds • Real-time DLR Tracking
Dual Protocol Ingress: SMPP and HTTP
Onboard both wholesale telecommunications partners and web developers seamlessly on a single dedicated switch.
SMPP v3.4 Server Daemon
Issue dedicated credentials to wholesale clients. Supports transmitter, transceiver, and receiver binds, custom window sizes, TON/NPI validation, and concatenated multipart SMS via User Data Headers (UDH).
RESTful HTTP Sending API
Clean JSON message submission endpoints with Bearer token authentication. Returns immediate HTTP 202 acceptance with message UUID; delivers asynchronous webhook delivery receipts (DLR) to client endpoints.
Granular Route Mapping & Balance Protection
Manage upstream supplier binds and protect your profit margins before traffic is transmitted.
Multiple Supplier Binds
Add and manage multiple upstream SMPP client connections. Set per-supplier bind credentials, ports, system types, and throughput throttles (TPS limits).
Prefix-Based Routing
Route messages deterministically based on destination E.164 country codes and MCC/MNC mobile network prefixes with automated priority fallback chains.
Prepaid Balance Quotas
Prevent revenue leakage. Rate decks automatically calculate message costs and deduct from client balances, rejecting traffic if credit is depleted.
