What it does

validateemail.io is an email validation API that checks any address in milliseconds with one call. Block typos, fake domains, disposable inboxes and dead mail servers at sign-up, and keep your sender reputation clean. Every request runs a full pipeline and returns a single verdict, a confidence score, and the result of each individual check, so you decide how strict to be. Standards-based parsing catches malformed addresses, illegal characters, bad dots and over-long parts. International domains are converted to punycode. Live DNS lookups confirm the domain is registered and resolving, so made-up and mistyped domains are rejected instantly. We look up the domain's mail servers, respect…from validateemail.io

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
