SimplyRCS is Signalmash's RCS Business Messaging platform for US brands. It sends verified, branded RCS messages with rich cards, carousels and suggested actions into the default Messages app on Android and iPhone, with automatic SMS and MMS fallback for handsets that cannot receive RCS. Marketing and operations teams build campaigns and AI-driven bots in a no-code builder, handle two-way conversations from a shared inbox, and measure delivery, reads and button taps in real time. Developers get a public REST API with 195 documented endpoints, signed webhooks and an MCP server. Signalmash handles brand registration, 10DLC, carrier vetting and Google RCS sender verification in-house, so a first verified US send typically takes two to four weeks, and numbers can be ported from an existing provider. Pricing is published: the platform is free, RCS or SMS text messages are $0.0039, messages with media are $0.0150, and each verified RCS agent is $250 per month, with carrier and registry fees passed through at cost. The service runs on direct Tier-1 US carrier connections (AT&T, Verizon, T-Mobile) and is SOC 2 Type II certified.
