Protecting Your App from Disposable Emails with MotaDev API
Disposable email addresses are one of the biggest problems for modern apps and websites.
They are often used for:
- Fake account creation
- Spam registrations
- Free trial abuse
- Bot attacks
- Coupon abuse
- Bypassing bans
If your platform allows temporary email services like Mailinator, Guerrilla Mail, or 10 Minute Mail, your database can quickly become filled with fake users.
In this guide, you'll learn how to protect your application using the MotaDev Disposable Email Detection API.
What is a Disposable Email?
A disposable email is a temporary email address that users create for short-term use.
Examples include:
test@mailinator.comrandom@tempmail.comabc@10minutemail.com
These emails are usually destroyed after a few minutes or hours.
Why Blocking Disposable Emails Matters
Blocking temporary emails helps you:
√ Reduce spam accounts
√ Prevent fake signups
√ Protect free trials from abuse
√ Improve user quality
√ Keep your analytics clean
√ Reduce bot registrations
API Endpoint
POST https://api.motadev.xyz/mail
Authentication
The API uses a simple API key passed in headers.
key: motadev@beckham
Request Headers
| Header | Value |
|---|---|
| key | Your API key |
| Content-Type | application/json |
Request Body
{
"email": "test@mailinator.com"
}
Python Example
import requests
url = "https://api.motadev.xyz/mail"
headers = {
"key": "motadev@beckham",
"Content-Type": "application/json"
}
data = {
"email": "test@mailinator.com"
}
res = requests.post(url, headers=headers, json=data)
result = res.json()
# IF checks...
if res.status_code == 200:
if result.get("success") is True:
print("Disposable email detected •••")
elif result.get("success") is False:
print("Email is clean √")
else:
print("Unexpected response format ×")
else:
print("Error: ", result.get("message"))
Example Responses
Disposable Email Detected
{
"success": true,
"message": "Disposable email detected"
}
Clean Email
{
"success": false,
"message": "Email is clean"
}
How It Works
The API checks whether the submitted email belongs to a known disposable email provider.
If detected:
- The API returns
success: true - Your application can reject the signup
If not detected:
- The API returns
success: false - The user can continue registration
Integrating into Your Signup System
You should validate emails before:
- Creating accounts
- Sending verification emails
- Activating free trials
- Processing registrations
Example logic:
if result.get("success") is True:
return "Registration blocked"
else:
return "Registration allowed"
