Resend grew from 106,000 MCP calls in April to 3 million in September as agents recommended it, after Jason Lemkin's agent steered him away from SendGrid.

Jason Lemkin said his first agent-driven purchase was Resend for email. Agents kept recommending SendGrid, but he couldn't get it working: free access had been deprecated, he couldn't figure out the key and it kept breaking. When he asked his agent what to use, it said Resend. He cited the MCP call growth as evidence of agents choosing products.

“Resend April, 106 ,000 MCP calls to September, 3 million. That's agents saying to use products.”
