It's not exactly too hard to read the Reddit post
Yeah, it's a bit hard to say whether they work or not. This is why I added my own website with real users interacting with confirmation emails

The email was delivered 100% of the time to Gmail, but not at all to Yahoo and Outlook. The delivery rate to these two companies started to get better around last week, though. Some IP addresses started getting a 100% de
