Telgorithm

Overview

Telgorithm Inc. was founded in 2021 and sells SMS, MMS, RCS and voice APIs to software platforms that send A2P messages for their own customers in the US and Canada. Customers must be registered Campaign Service Providers with The Campaign Registry and commit to at least 500,000 messages a month. Its patented Smart Queueing paces traffic to carrier rate limits so messages are queued instead of failing. It has no iMessage or WhatsApp.

Key features

• Messaging API for SMS, MMS and group MMS on 10DLC and toll-free numbers
• RCS Business Messaging (described as beta) with rich cards, suggested actions, seen receipts and SMS/MMS fallback
• Campaign import from TCR, free number porting and hosted SMS
• Voice: inbound call forwarding, two-leg outbound calls and recording
• Webhooks with retries over 24+ hours and a Webhook History API
• Staging environment with a testkit that emulates inbound messages and calls
• Carrier lookup API

Pricing

Outbound SMS starts at $0.005 per segment on 10DLC with free inbound, MMS at $0.015, RCS at $0.008 per Rich Message segment or $0.072 per 24-hour conversational session, voice from $0.0065 a minute and numbers at $0.50 a month. Carrier fees are extra. Self-serve signup includes $100 in credit.

How it compares to Linq

Linq sends iMessage, RCS and SMS from managed lines with flat pricing from $260 a month and no per-message fees. Telgorithm has no iMessage and bills per segment, session and minute, with a 500,000-message monthly minimum. Telgorithm places outbound calls, while Linq's docs say its API does not place or answer calls. Linq publishes TypeScript, Python and Go SDKs and an MCP server; Telgorithm offers an OpenAPI spec for generating clients.

Best for

US software platforms that are already TCR CSPs and send high-volume 10DLC traffic for many brands.
