inbound ▲227Hey HN! I've been working on Inbound (inbound.new) - an email system that lets you programmatically manage email addresses and route them to AI agents, webhooks, or forward them anywhere.

Now I help companies fix poor email deliverability and boost their email ROI. I want this checklist to be a repository of email best practices so I'm always looking to improve and update…
