SimplyRCS
SimplyRCS is a US-focused platform for sending verified branded RCS, SMS, and MMS business messages. It supports broadcasts to lists or segments, two-way conversations, and automatic fallback from RCS to MMS or SMS. Users can describe a bot in plain English, then edit the AI-assembled bot on a visual canvas. Analytics cover delivery, reads, taps, conversions, and cost, with CSV exports and scheduled reports. Named integrations include Salesforce, HubSpot, Zoho, Shopify, scheduling and EHR systems, and helpdesks; a REST API with webhooks is also available. The public API documents 195 endpoints across messaging, sender IDs, bots, contacts, compliance, analytics, and webhooks. SimplyRCS says it checks consent before sends, honors STOP and HELP immediately, enforces quiet hours, and logs consent events. The free plan has no platform charge, with messaging at published rates; paid plans start at $20 a month. Separate sender fees include an annual 200.00 USD Aegis review and a one-time 500.00 USD T-Mobile activation.
