Catch Throwaway Emails Before They Hurt Your Business
Fraudo.io’s free disposable email detection tool helps you find out if an email address is real or temporary before fake signups, trial abuse, or bot activity mess with your platform. Fraudsters use temporary inboxes to get in fast and leave even faster. You can stop them before they get in.
Test Any Email Instantly
Enter an email address to check if it’s temporary, disposable, or
suspicious.
(No signup needed — it’s free to try.)
What Are Disposable Email Addresses?
Disposable email addresses are temporary inboxes anyone can create in seconds — no password, no ID, no trail. People use them to get around email verification, spam your platform, or sign up multiple times for offers they shouldn’t. And once they’re done, that inbox is gone.
They create fake accounts that waste your time and budget. If your platform depends on real users and clean data, disposable email detection isn’t just helpful, it’s necessary.
Why Detecting Them Matters
Let’s say you run a subscription service. You offer a 7-day free trial, no credit card required. Someone creates a new disposable email every week just to keep signing up for free. That’s money lost.
Or maybe you're sending marketing campaigns, and 30% of your list bounces because of fake inboxes. That drags down your sender reputation and wastes your team’s energy.
Whether you’re protecting signups, sales funnels, or email campaigns, fake inboxes do real damage. Fraudo.io helps you stop that at the source.

How Disposable Emails Are Used for Fraud
If someone wants a free trial 10 times, they won’t use 10 Gmail accounts. They’ll spin up 10 fake inboxes using a disposable email service.
These emails:
- Bypass signup validation
- Disappear after minutes or hours
- Are never monitored
- Are used for spamming, abuse, and phishing
- Often go hand-in-hand with VPNs, bots, or stolen data
We’ve seen it all. You don’t want them in your system.
