Email API for developers to send transactional and marketing email

Resend ships a tight, frequent changelog: richer email content and deeper dev-tool reach

email-apideveloper-toolsintegrationsmcpai-nativecontacts
◆Current state
Resend is executing the developer-first email playbook with a clean, high-cadence changelog of real features. Recent releases split cleanly between richer email/editor capabilities (Open Graph previews, embedded charts) and embedding Resend into the tools developers already use (Vercel, Claude Code, Auth0, MCP).
◆Where it's heading
Two arcs are compounding: AI-native composition (mentions in AI chats, AI column mapping on CSV import, chart components) and distribution through integrations (Vercel Marketplace, an official Claude Code plugin, an MCP server, Auth0). Resend is trying to be the email layer that shows up wherever devs and agents already are, not a destination they visit.
◆Prediction
Expect more agent- and MCP-facing surface plus marketplace integrations, alongside continued audience tooling building on the CSV import. The cadence is steady incremental execution rather than big directional bets.
