What it does
ListSweep checks an email list before you send it: syntax, MX, live SMTP, catch-all, disposable, role and spam-trap detection, with a 0-100 score per address. $79 covers a million verifications a month. A free Windows app runs the same engine offline.
Verify and clean email lists in bulk. 10 checks - syntax, MX, SMTP, disposable, spam-trap, gibberish - to cut bounces, protect deliverability, and lower ESP costs. Free to start.
ListSweep validates email addresses at scale using syntax rules, MX record lookups, live SMTP verification, disposable-domain and spam-trap detection - so every campaign lands in real inboxes, not bounce reports. Every control documented on our security page . Accuracy methodology on the benchmark page . Public trust links on the proof page . The core validation engine is already competitive. The remaining objections are the predictable ones: formal certifications, deeper native integrations, and heavier public proof. ZeroBounce, Bouncer, Kickbox, Emailable, and Clearout all market stronger current certification coverage than ListSweep today. Incumbents and newer challengers like TrueList…from listsweep.com

Talanoa▲345Hi 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…
