SlickText's feed is all SMS buying guides; no product release has surfaced since RCS.
SlickText's recent feed is entirely search content: SMS segmentation, church and nonprofit texting comparisons, Black Friday tactics, cost breakdowns and guides on annual plans. No release appears in the entries since the basic RCS addition.
Notification infra platform invests in developer ergonomics — MCP, CLI, Templates 2.0, OTEL.
SuprSend has been shipping for a developer-first audience: Templates 2.0 with variants and a redesigned editor (one template per channel, with tenant/language/plan branches), a programmatic Messages API for fetching and updating delivery state, zero-install CLI and MCP server via npx, native monitoring integrations for Datadog, New Relic, and OpenTelemetry. CLI updates also added automatic SKILLS.md generation and fixed a corrupted Node SDK package-lock.

The content is getting more explicit about buying decisions. Vertical comparison pages, published prices and an outgrown-your-platform pitch all aim at people ready to switch. Product motion cannot be read from these posts.
Expect Black Friday content through November and more vertical comparison pages. These entries give no evidence of how RCS is progressing.

SuprSend is positioning as the notification infrastructure that backend engineers — and the AI coding agents working on their behalf — actually want to use. The MCP-server and CLI-via-npx work, plus Claude Code plugin refresh, signal a deliberate AI-native posture. Templates 2.0 is the structural play: one template that resolves to the right variant per tenant/language/plan removes a real maintenance burden for multi-tenant SaaS and i18n use cases, which is where notification infra usually breaks down at scale.
Expect deeper Inbox/in-app notification primitives now that the Messages API is programmatic, more advanced Templates 2.0 variant logic (likely conditional fragments and content reuse), and broader observability surface — possibly per-workflow SLO tracking. Continued investment in MCP/agent-callable workflows is highly likely.
