Tells.co Launches Developer Hub for CRM SMS
Tells.co has opened a developer integration hub to help CRM and SaaS product teams add messaging capabilities such as SMS, MMS, RCS, voice agents, webhooks, and number intelligence via a single OAuth2-authenticated REST surface. The hub (tells.co/developers) is a documentation directory that guides engineers to the appropriate integration path, while Tells handles carrier operational tasks including 10DLC, short code, and toll-free registrations and carrier follow-ups. The company published a developer evaluation comparing Tells and Twilio and provides account-provisioned API access with endpoint references, SDKs, a Postman collection, and a sandbox during onboarding. David Schlaegel, Co-Founder of Tells.co, is quoted explaining product teams’ preference for one integration and outsourcing carrier operations.
Vendor documentation and integration guidance lowers engineering friction for CRM/SaaS teams adding messaging, but impact is vendor-level and not industry-shifting.

Tells Launches RCS Business Messaging for Verified Brands
Tells announced general availability of Tells RCS Messaging in the United States on June 9, 2026. The product delivers verified-brand RCS messages to both iOS and Android using Google’s RCS Business Messaging and Apple’s RCS Universal Profile, and provides automatic SMS fallback through a single API call. Verified senders display brand logo, registered name and a verification checkmark in recipient threads. The platform supports rich cards, carousels, suggested replies, action buttons (call, URL, calendar event, one‑time location), read receipts and typing indicators where supported. Tells says throughput for verified brands is comparable to short code SMS, and the capability is available to existing and new Tells customers after completing brand verification. Developer documentation and sample payloads are published in Tells’ developer portal.
Tells.co First to Launch RCS Messaging in the U.S.
Tells.co, an AI-powered high-volume messaging platform, announced it has been approved to deploy RCS Business Messaging in the United States, placing the company among the first U.S. platforms able to run production RCS campaigns. RCS (Rich Communication Services) enables app-like, rich-media interactions inside a consumer’s default messaging app — including high-resolution images, interactive buttons, branded sender identities and product carousels. Tells.co said it has launched advanced RCS features such as AI-generated personalized video messages, interactive product carousels with action buttons, verified branded sender profiles, and rich action links for tap-to-call, appointment scheduling, payments and directions. The company framed the approval as an early advantage as RCS gains momentum following Apple’s adoption and expanding carrier support in the United States.
