IsItDisposable

Stop throwaway emails before they hit your database

What it does

IsItDisposable detects disposable and throwaway emails at signup. Stop trial abusers cycling burner emails through your free tier, and keep throwaways from wrecking your list quality. A live dataset of 211,812 domains, MX-validated and refreshed daily, with about 320 new ones appearing every day. One API call or a drop-in script tag, and it fails open: if we are ever down, signups keep working. Relays like Apple Hide My Email are flagged, not blocked. Free plan plus a 14-day trial, no card.

Disposable email detection that protects your signups, your sender reputation, and your metrics. A drop-in snippet and a clean REST API return a verdict your policy maps to allow, warn, or block. DNS-level detection, no SMTP probing, fails open. Try the live demo.

Every throwaway address in your database is a bounced campaign, an abused product trial, or a metric you can no longer trust. A drop-in snippet and a clean REST API catch them at the form, in one fast DNS-level lookup, and your policy decides what happens next. A live look at the real engine, rate limited and never billed. Get a key to call it from your own app. Live numbers from the dataset behind every check, refreshed daily. Explore the data Disposable mailboxes live for about ten minutes, then take a piece of your business with them on the way out. Here is what each one actually costs. Temporary mailboxes vanish minutes after they are created, so every email you send afterwards hard…from isitdisposable.com

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
