Most people don’t really think about email addresses and how to validate if they are correct or not but developers have to do that frequently so that their applications can ensure people don’t input invalid data into the system. At first glance this seems like a fairly simple task but like all things the devil is in the details.
Sam Rose over at Mastodon shared a link to an interesting site with an Email Quiz that asks visitor to decide if each email address shown is valid or not. I tried it out earlier and only managed to get a little over 50% of the answers correct. You should check the site out and see what you score.
