The Cost of Fake Signups
Temporary emails and disposable accounts waste engineering time, distort metrics, and increase support costs.
Fake Account Pollution
Users create throwaway accounts with temporary emails to abuse free trials, grab promotions, or spam your platform.
Support Ticket Waste
Temporary emails can't receive password resets or notifications, generating unnecessary support tickets from real users.
Misleading Metrics
Inflated signup numbers from fake accounts make it impossible to calculate real conversion rates and user engagement.
Integrate in Minutes, Not Days
Choose your integration method: client-side, server-side, or webhook-based
// Client-side validation (React)
import { useEmailValidation } from '@antitemp/react'
function SignupForm() {
const { validate, loading, result } = useEmailValidation()
const handleSubmit = async (email) => {
const validation = await validate(email)
if (validation.risk_score > 70) {
setError('Please use a permanent email address')
return
}
// Proceed with signup
submitSignup(email)
}
return <input onChange={(e) => validate(e.target.value)} />
}Client-Side Validation
Validate emails as users type with React/Vue hooks. Instant feedback without page refresh.
