There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that.

与 CRM、Slack 和 Claude 集成的电子邮件收件箱。
thomas_housecat · HN
I got so frustrated with all of the busywork that was building up in my email inbox that I built something better. Housecat is the first email inbox that helps you get real work done. Our email connects to the other services you actually use like your Claude, Notion, Slack, CRM and Github and makes it easy to send messages and data between them. So if you need to update the CRM with a new lead, track a Github issue or ask a question of a colleague in Slack, you can do it all from right inside of
