What is Sendly?

Sendly is an infrastructure-as-a-service platform built explicitly for the needs of AI agents and developers. It provides a specialized layer for SMS communication, allowing autonomous agents to send and receive text messages programmatically.

Why Founders Need It

As AI agents move beyond the browser and into real-world workflows, they require reliable channels to interact with human users. Sendly removes the friction of configuring traditional enterprise SMS APIs, offering a streamlined experience tailored for high-frequency, automated agent interactions.

How to Use It

  • Integrate the SDK directly into your agentic workflow.
  • Configure webhooks to allow your AI to respond to incoming SMS prompts.
  • Use the API to trigger proactive notifications based on agent-detected milestones.

Integrations & Alternatives

Sendly is designed to integrate into standard developer stacks. While industry giants like Twilio and Vonage dominate the general market, Sendly differentiates by focusing on the specific latency and formatting requirements of LLM-driven communication.
