I used Google way back in the day for a custom domain, but eventually got off that bandwagon and decided to host my own. Found that hosting my own was great for receiving emails, but a huge pain for sending. Eventually had to give that up too. I've used ProtonMail with that same custom domain since 2016. The mobile apps, web interface, and features have all gotten much better over time. That being said, I don't use a lot of personal emails anymore, and am considering iCloud from Apple. The only reason where I think iCloud is an improvement is because when signing up for an account that requires an email, Apple will automatically generate a 'relay' address for me. These relay addresses can be deleted at anytime, which solves the "unsubscribe from mailing list" that no company has ever honored. And really, that's all I look for in personal email provider. A way to make sure I only get a handful of messages in my inbox a week, and all the spam gets trashed.
