If you have your own domain, I recommend Migadu. They take care of all the boring parts of hosting email, while being cheap and very reliable. All you have to do is[1] follow their guude to setup some DNS records and double check everything is right. After that, you have a working email account with unlimited addresses, inboxes and a bunch more nice features.
[1]: Besides getting a domain name, which you should get anyway, since it gives you more control over your digital identity and makes it much easier to migrate providers in the future.
