Many email providers blacklist large parts of the internet for spam protection. When I switched from hosting my own email (doing SPF, or whatever existed back then) to paying fastmail to host my email a lot more email started going through. fastmail is large enough and has a good enough reputation that nobody can afford to block emails from them. I still have my own personal domain most people who email me have no clue that I'm not hosting it. I'd advise the same thing, pay fastmail to host your email, it doesn't cost much and everything works.
There are companies other than fastmail that does this as well. Some of them are just as good, pick whichever you want.
Not really - keyboards need to be much farther from the screen than that. Laptops are terrible for the same reason. Maybe your body can accept that bad ergonomics, but mine cannot. which is why I carry a separate keyboard for my laptop and phone. (plus mechanical keyboards are much better anyway)
