What is SimplyRCS?

SimplyRCS is a business messaging platform developed by Signalmash that provides SMS Marketing, Rich Communication Services (RCS), and multi-channel mobile messaging for enterprise brands. The platform delivers verified messages containing rich cards, carousels, and interactive action buttons to mobile devices, featuring automated fallback to Multimedia Messaging Service (MMS) and Short Message Service (SMS) for non-RCS handsets.

Key Capabilities
  • Unified Multi-Channel Provisioning: Consolidates RCS, SMS, MMS, toll-free numbers, short codes, and 10-Digit Long Code (10DLC) senders under a single administrative account. Manages brand vetting, 10DLC registration through The Campaign Registry, toll-free verification, and RCS agent approval.
  • Visual Campaign Builder: Features a visual design canvas to construct interactive conversational flows, multi-option menus, input forms, carousels, and automated handoffs to live agents. Supports list segmentation and pre-send message cost previews.
  • Shared Inbox & Telemetry: Provides a centralized inbox for two-way customer communication with agent assignment and escalation routing. Delivers real-time reporting on message delivery, read receipts, button taps, conversion metrics, and per-channel expenditure.
  • Developer & AI Agent Interfaces: Exposes a unified REST API endpoint for message delivery across all channels, supported by signed webhooks, scoped API keys, an OpenAPI 3 specification, and a Model Context Protocol (MCP) server for AI agent integrations as a Communications Platform as a Service (CPaaS) solution.
  • Compliance & Consent Enforcement: Maintains a SOC 2 Type II security posture, logs consent events to an immutable audit trail, enforces quiet-hour delivery rules, and automates STOP and HELP opt-out handling.
