Email
Setup
User-supplied API key

Setup

You supply your own SendGrid credentials as environment variables on your app — SENDGRID_API_KEY. Add them under Settings → Environment Variables, mark them secret, and call SendGrid from a server-side endpoint so the keys never reach the browser.

Build with SendGrid

Open OverSkill, describe what you want to build, and reference SendGrid in your prompt — the AI will wire up the integration automatically.
