You can do it, but spam filters are so extreme that you may find your mail goes undelivered or auto-filtered into spam. Small hosting companies struggle with email deliverability, so you have to ask yourself if it's something you want to deal with. Sometimes if you end up on a blocklist there's no easy way to get off of it, and you may find yourself unable to get an email into someone's inbox until you have the time to redo a lot of work (moving to different servers, IPs, etc). From my perspective, you're better off using your time to do literally anything else unless email is something you want a very deep understanding of.
