What Is DIGITS Email Filter?
DIGITS Email Filter is developed by Digits and is an authentication plugin for WordPress. It belongs to the authentication category on WPExclusive, alongside other tools for secure user management and verification.
The plugin solves the growing problem of bot registrations and spam accounts that use burner email services to bypass verification. It is built for site owners who need to maintain high-quality user data and prevent automated signups from cluttering their database.
DIGITS Email Filter Features
The core feature set is built around real-time domain filtering and automated protection against disposable email providers.
Disposable Email Prevention
The plugin utilizes an extensive server-side list of disposable email websites and domains to detect burner accounts instantly. When a user attempts to sign up with a temporary address, the plugin identifies the domain and blocks the registration attempt. This creates a proactive barrier against spam without requiring manual moderation of new users.
Custom Domain Management
Administrators can take granular control by manually blocking signups from specific domains or whitelisting others. This is particularly useful for corporate environments or private communities where registration must be restricted to specific professional or academic email providers. The interface allows for quick updates to these lists as your site requirements change.

Use Cases
Preventing Spam Registrations on Community Sites
Sites using authentication systems often suffer from bot-generated accounts that bloat the database. Email Filter prevents these entries by rejecting the domains typically used by automated scripts to generate disposable identities.
Restricting Signups to Corporate Domains
For internal company portals or private membership sites, you can whitelist specific organizational domains. This ensures only users with authorized emails can access the registration process while blocking all public or burner providers.
Agencies and Developers Managing Multiple Client Sites
Developers can deploy this addon across various client projects to reduce maintenance overhead related to spam cleanup. A WPExclusive membership allows for deployment on unlimited sites with a single subscription fee.
