A side-by-side look at the SendGrid Transactional and E2a — email for AI agents MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose SendGrid Transactional for communication work as a local process; choose E2a — email for AI agents for communication as a local process. You can also run both side by side in one mcpServers block.
