The EU is interesting because there is the GDPR that has good data privacy protection but then they keep bringing up chat control which completely undermines privacy

You can try doing it yourself by using the intel techniques workbook instead. Start with the most bang for your buck removals. https://inteltechniques.com/workbook.html

Yeah. Not sure it will be a long term solution. But needed something for now while I migrate away from mailbox.org. Thankfully I didn't use the mailbox.org aliases much so it is pretty simple to switch providers.

I ended up just doing skiff free version for the time being. It is allowing me to use custom domain and it gives me a couple skiff aliases I can use. Only thing I don't like is it forces me to use the app and no notifications without Google play services.

migadu does seem like a good option. Curious what you have chosen? I am also looking at fastmail standard to replace simplelogin email aliasing since it would be the same price as simplelogin + migadu/runbox.

Did not know this... Also currently on the 1 EUR plan since it was the best bang for buck that included custom domains. Might start looking into other options when my plan runs out
