The Best SendGrid Alternative for Email API

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

SendGrid is a mature email platform inside Twilio, but it runs on a separate API surface. Telnyx puts Email, SMS, Voice, WhatsApp and AI inference on one account, one API key, and one invoice. 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.
