The Best Resend Alternative for Email API

One email API. Used for every channel. Easy integration to AI agents.

Resend is a developer-first email platform with excellent SDK and React Email ergonomics. But Resend is email-only, with no native SMS, Voice, or WhatsApp APIs. Telnyx puts Email, SMS, Voice, WhatsApp and AI inference on one platform. Teams can use Telnyx agent skills to build in minutes and connect one communications API to AI inference so agents can send, respond, and escalate across channels.
