This is a Python package containing a single module webmail_domains.py, itself containing a list of webmail domains.

Feel free to make pull requests, and I'll add them in.

Installation

pip install webmail-domains

Usage

import webmail_domains

if <some_email>.split('@')[1] in webmail_domains.WEBMAIL_DOMAINS:
    # do something (reject signup, don't add the domain to a CRM, etc.)
