disposable email detection tool

If you want a disposable email detection tool, here are good options depending on what you need:

Ready-made APIs

• ZeroBounce
• Kickbox
• NeverBounce
• Abstract Email Validation
• Mailgun Email Validation

These typically detect:

• disposable/temporary domains
• invalid syntax
• mailbox existence
• role-based emails
• spam traps (some vendors)

Open-source / DIY approach

You can build a simple detector by:

1. Maintaining a blocklist of known disposable domains
2. Checking MX records
3. Using an email validation API
4. Scoring risk based on domain age, pattern, and DNS behavior

Simple Python example

disposable_domains = {
    "mailinator.com",
    "10minutemail.com",
    "guerrillamail.com",
    "tempmail.com"
}

def is_disposable(email):
    domain = email.split("@")[-1].lower()
    return domain in disposable_domains

print(is_disposable("test@mailinator.com"))  # True

If you want a production-grade solution

Use a vendor API because disposable providers change frequently and maintaining the domain list yourself becomes hard.

If you want, I can also provide:

• a Python script
• a JavaScript function
• a FastAPI/Flask endpoint
• or a database of disposable domains
