I'm an engineer at Town (town.com) -- morning briefing + email digest is literally a stock workflow we ship. You connect your accounts and it just runs. No self-hosted stack to babysit, so it doesn't break when we push updates (that was a fun problem to solve on our end tbh). Free right now if you want to try it.

Yeah, I don't think it's a feature unique to open claw in anyway. But combined with the memory of what I have going on and the other personal/business context it ended up being a fun experiment that didn't take me long to set up.
