Bounceless

What it does

Verify, validate and clean email lists at scale with one API. Power AI sales agents with deliverable email data.

The complete toolkit to verify, validate, and clean your email lists at scale. One API. Built for revenue teams who need explainable Pre-Send Decisions — not raw bounce guesses or borrowed customer logos. A "valid" SMTP handshake doesn't mean the mailbox is safe to email at scale. Catch-all domains accept everything and reveal nothing. Treating them as valid is a guess. One bad send can hurt sender reputation for every campaign that follows. Most verifiers stop at valid or invalid and leave the risk call to you. Bounceless adds a Pre-Send Decision: confidence, reason codes, and honest uncertainty on catch-all and major webmail, so your team decides before the send, not after the bounce.…from bounceless.io

  A blocklist to remove spam and bad websites from search results2025 · github.com · ▲225

  Hi HN! I've been fed up with search results so much that I decided to make a giant blocklist to remove garbage links by using uBlacklist. I browsed other blocklists and wasn't very satisfied from what exists now; the goal of this one is to be super organized and transparent, explaining why each site was blocked via issues. Contributions welcome! Even though around 100 domains are blocked so far, I already noticed a big improvement in casual searches. You'd be surprised how some AI generated websites can dominate the #1 page on DuckDuckGo.

  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…
