Stop Fake Signups Before
They Hit Your Database.
Every disposable email is a lie about your traction. Every bounce is permanent damage to your sender reputation. Protect your SaaS, block burner domains, and catch fat-finger typos before you lose the lead.
Live API Demo
Try a typo like user@gmil.com or a burner like test@yopmail.com
Save The Fat-Fingers
Someone types "gmil.com" because they're rushing. Don't lose the user. Catch the typo and autocorrect it with one click.
Block The Burners
Automatically reject temp-mail and 100,000+ known disposable providers. Keep your metrics honest and your database clean.
Verify Reality
We ping the domain's live DNS/MX records in milliseconds. If it can't receive email in the real world, it doesn't get past your form.
Why Email Validation Regex is Dead
Most developers rely on standard javascript regex (like ^[^\s@]+@[^\s@]+\.[^\s@]+$) to validate forms. Regex only checks syntax, not reality.
A regex will happily accept user@temp-mail.org or john@gmil.com because they look like valid emails. This leads to high bounce rates, ruined sender reputation, and a database full of garbage.
