I found Migadu through a HN post like this and can't recommend them enough. It feels like having my own mail server without the headaches. The pricing model works for me and I find the control panel really well laid out. I don't think I could return to an email provider that leases emails at my own domain back to me.

Wow, this is exactly what I'm looking for. How often do emails you send go to other people's spam? Do you know people with an outlook email?

I've not experienced that problem. I'm uncertain how many Outlook inboxes I've mailed, but I have done so and they did work.
