I think self-hosting is the wrong choice for most people. The effort you need to put in to first build out the system, and then maintain it, and all the while jump through the various hoops that are required to have Google, Microsoft, Apple, etc, accept email from you, is significant. $50/year is a bargain if you value your own time at minimum wage or more.
