Dead-Letter

Description

This wordpress plugin utilizes our daily dump of disposable email address domains to detect the use of disposable email addresses.

It uses the WordPress internal is_email hook, therefore it integrates seamlessly into 3rd party plugins like WooCommerce, Gravity Forms, Jetpack and every other plugin that uses the is_email() function.

This plugin follows the “Privacy by design” principles by not sharing any personal informations of your users with 3rd parties. By installing/activating this plugin, you agree, that you’ve read and understood our privacy policy.

Installation

Download, Install and forget!

As of now, there are no options. So you can easily install and forget it. It works right after it’s installation/activation.

FAQ

What API is used?

The Dead-Letter plugin for WordPress doesn’t use any external API. Every 24 hours, we publish an updated list of disposable email domains. This list is publicy accessible here: https://www.dead-letter.email/blacklist_flat.json. This plugin just pulls this list every 24 hours and saves it locally.

We think, that this is the most reliable and privacy friendly solution.

How is the list generated?

Business secret 😉

Is there any way to exclude domains from being blocked?

Currently not, but that’s already on our list.

How can i report undetected domains?

Contributing to this project is easy as 1-2-3, even without a Github account. If you have a Github account, just create an issue and list all domains you believe they are missing in the list.

If you don’t have a Github account or prefer staying anonymous, use our Git Reports form.

However, before creating an issue, please make sure, that the concerning domain is really undetected. To do so, simply perform a quick check at https://www.dead-letter.email
