About Resend
The developer email API is rebuilding itself as something agents log into, not just call
Resend shipped at a near-weekly pace through July and almost all of it points one direction. A hosted MCP server with built-in OAuth, a one-click Claude connector, and a Codex plugin bundling the MCP server and every Resend skill all landed within three weeks, sitting on OAuth 2.1 with PKCE that arrived alongside them. The rest is platform hygiene: Message-ID exposed on webhooks and email endpoints, CSV contact import at scale, suppression management, and automatic revocation of API keys leaked to GitHub.
