python-disposable

A lightweight Python package to detect disposable/temporary email addresses. Bundles 72,000+ domains from disposable/disposable-email-domains, updated daily — no network calls at runtime.

Installation

pip install python-disposable

Usage

Basic check

from disposable_email import is_disposable, is_valid

is_disposable("user@mailinator.com")  # True
is_disposable("user@gmail.com")       # False

# Works with bare domains too
is_disposable("guerrillamail.com")    # True

# Inverse
is_valid("user@gmail.com")            # True

Strict mode

Strict mode also flags greylisted domains — services that allow anonymous signups but aren't purely disposable (e.g. some free email providers).

is_disposable("example.com", strict=True)
is_valid("example.com", strict=True)

Subdomain handling

Subdomains are automatically resolved to their parent domain.

is_disposable("mail.mailinator.com")     # True
is_disposable("a.b.guerrillamail.com")   # True

Get the full domain set

from disposable_email import get_domains

domains = get_domains()              # frozenset of 72k+ domains
domains_strict = get_domains(strict=True)  # frozenset of strict list

Domain count

from disposable_email import domain_count

domain_count()              # 72170
domain_count(strict=True)   # 26468

Django example

from django import forms
from disposable_email import is_disposable

class RegisterForm(forms.Form):
    email = forms.EmailField()

    def clean_email(self):
        email = self.cleaned_data["email"]
        if is_disposable(email):
            raise forms.ValidationError("Disposable email addresses are not allowed.")
        return email
