Email Verification and Validation API

What it does

Email Verification & Validation API Verify emails in real-time with 6 independent checks: syntax, MX records, disposable domains, role-based detection, typo suggestions, and catch-all detection. Returns a 0–100 score. No paid services, fully open source, and transparent about limitations. Single and bulk endpoints available.

The Email Verification and Validation API tells you whether an email address is real, deliverable, and worth sending to — before you send anything. Every address goes through a 7-step pipeline: 1. Syntax validation — Checks the address against RFC 5322 rules and length constraints. 2. MX record lookup — Confirms the domain is configured to receive email. 3. Disposable domain detection — Flags addr

  Email Validator by SidemailFeb 2026 · sidemail.io · ▲16

  Talanoa▲346

  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…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
