10 Minute Mail

What it is

10 Minute Mail provides exactly what its name says — a 10-minute disposable inbox. Refresh the page and you get another 10 minutes; close it and the inbox is gone. Spawned dozens of copycats.

Why signup forms see so many of these

The 10-minute lifetime is just long enough to receive a signup confirmation. The brand is so well-known that "10minutemail" has become a generic term for any disposable inbox service — users who don't care about anonymity still use it as the default.

Block 10 Minute Mail the right way

Send the signup email to GET https://api.checkdisposable.email/v1/check?email=<email> with a Bearer API key. If is_disposable is true, reject the signup.

// node — block 10 Minute Mail + all aliases in one call
const r = await fetch(
  `https://api.checkdisposable.email/v1/check?email=${encodeURIComponent(email)}`,
  { headers: { Authorization: `Bearer ${process.env.CDE_KEY}` } }
);
const { is_disposable } = await r.json();
if (is_disposable) {
  return res.status(400).json({ error: 'Please use a real email address.' });
}
// continue with signup
