Great walkthrough! I built something similar for automating cold email tracking — having a local MCP server handle SMTP without routing through a cloud service is a huge win for deliverability. One thing I would add: rate limiting at the server level (not just client-side) saved me from getting shadow-banned by Gmail. Took me a weekend to figure out why half my emails were going to spam.

Good call! Thank You!! That had crossed my mind with how fast it does calls sometimes... Sorry to hear about the gmail ban hammer. It doesn't take much these days LOL
