Resend wins the agent war

🔥 What happened Claude Code picked Resend first in 64 of 102 email recommendations – versus just 7 for SendGrid. Resend CEO Zeno Rocha joined the podcast to explain how his team has been doing "Agent Experience Optimization" (AEO) since 2024. Resend now has 4.3M users and 120K paying customers. 💡 Why it matters Agents decide which API developers adopt – and once your code lands in the patch, it rarely gets swapped. Resend's MCP server ballooned from ~20 to 80+ tools, while Cloudflare's Code Mode exposes just two (search/execute). The catch: oversized tool outputs blow the context window – a design flaw every MCP builder should test. ⚡ Our take Ignore AEO and you'll lose the next dev generation to a startup that serves its pricing page as .md. Cloudflare is asleep at the wheel – Resend is building the moat around the inbox.
