I finally got around to adding e-mail subscriptions to my website, like I said in my very first article. It wasn't really difficult but it's hard to find the time to work on all the side projects that I want to work on. I looked into several different mail services and I ended up choosing Mailgun. It was really easy to setup, and my first e-mail sent from my development environment even ended up in my inbox and not in my spam folder. I've tried hosting my own mail server long ago on a Raspberry Pi on my desk but all e-mail from it just ended up in the spam folder if not just outright rejected from the server completely. It's much much easier to let some other service handle mail for you.
At the top of the home page should be a field to enter your e-mail if you want stay tuned for more articles. I've got some more ideas that I hope to get to in the next couple months.
