<p>This plugin blocks spammers that try to send a contact form with an email address from the domain of the WordPress installation in Contact Form 7.</p>
<p>We have found more and more spammers that use an email address from the domain where the WordPress site is hosted in the form. We don’t want to receive contact forms with email addresses hosted on the domain. <strong>For example if the Contact Form is hosted on domain.com they use info@domain.com as the email address in the form to try to pass spam validations.</strong></p>
<blockquote>
<p>The plugin filters the email address in the Contact Form 7 field: <code>your-email</code>. If you are giving the email address another name it will not work correctly, so please use the standard <code>your-email</code> name.</p>
</blockquote>
<p><strong>Please only activate this plugin if you know what you’re doing</strong>.</p>
<h4>What ideas is this plugin based on?</h4>
<p>None. We needed a fast solution to block contact form submissions using dummy email address on the domain where the form is hosted.</p>
<h4>System requirements</h4>
<p>PHP version 7.1 or greater.<br />
We require 7.1 or higher because we believe that everybody should be running a modern PHP version. When releasing this plugin <a href="https://wordpress.org/about/requirements/" rel="ugc">WordPress recommends PHP 7.4 or higher</a>.</p>

<p>The Email Blacklist Add-on for Gravity Forms was built to help block submissions from users with generic or competitors email addresses. Prevent the user from processing the form and stop non-qualified leads from being collected.</p>
<p>This plugin allows site admins to create a list of domains that if used in an email field on a Gravity Form it will cause a validation error and block the submission. A default email blacklist and validation message can be created to use across all email fields. These default settings can be overridden on a per email field basis.</p>
<p>Global settings can be added on ‘Forms’ > ‘Settings’ > ‘Email Blacklist’. To add settings to an individual email field, select the field and navigate to the ‘Advanced Settings’ tab.</p>
<p>This plugin works by blocking either individual email addresses (ex. jsmith@gmail.com), email address domains (ex. gmail.com), and/or email address top-level domains (ex. *.com).</p>

<h3>Instructions</h3>
<h3>Global Blacklist Settings</h3>
<p>Once set up, these settings will be used on all email input fields across all the Gravity Forms used on the site. They can be overridden by the individual email blacklist settings below.</p>
<ol>
<li>Once Logged into your site navigate to ‘Forms’ > ‘Settings’ > ‘Email Blacklist’</li>
<li>In the ‘Global Blacklisted Emails’ input enter a comma separated list of blacklisted domains (ie. hotmail.com), email addresses (ie. user@aol.com), and/or include the wildcard notation to block top-level domains (ie. *.com). This setting can be overridden on individual email fields in the advanced settings.</li>
<li>In the ‘Global Validation Message’ input enter a default error message if a blacklisted email is submitted. This setting can be overridden on individual email fields in the advanced settings.</li>
<li>Select the ‘Global Invalid Entry Procedure’ to determine how the blacklisted submissions should be handled, with validation error or collected and marked as spam.</li>
<li>Click the ‘Update Settings’ button to save the settings.</li>
</ol>
<h3>Individual Email Input Blacklist Settings</h3>
<p>Once set up these settings will be used on this form only and in place of the global blacklist settings above.</p>
<ol>
<li>Once Logged into your site navigate to the Gravity Form you would like to update.</li>
<li>Add or update an existing email input field on the form.</li>
<li>Go to the ‘Advanced Settings’ tab for the ‘Blacklisted Emails’ input.</li>
<li>In the ‘Blacklisted Emails’ input enter a comma separated list of blacklisted domains (ie. hotmail.com), email addresses (ie. user@aol.com), and/or include the wildcard notation to block top-level domains (ie. *.com). This will override the globally defined blacklisted emails setting. Enter ‘none’ to bypass the global setting and allow all email addresses.</li>
<li>In the ‘Blacklisted Emails Validation Message’ input enter an error message if a blacklisted email is submitted. This will override the globally defined error message.</li>
<li>Select the ‘Invalid Entry Procedure’ to determine how the blacklisted submissions should be handled, with validation error or collected and marked as spam.</li>
<li>Click the ‘Save Form’ button to save the settings.</li>
</ol>
