Overview
The WordPress Email Registration Blacklist plugin enables you to block users whose domains have been blacklisted from registering on your WordPress website. This allows your WordPress site to stay free of spam, malware and viruses.
This user guide will help answer any questions you have about the free version of the plugin. For the pro version, please refer to this guide.
This plugin supports blocking registration by specific emails or domains or allowing only registration from predefined list of emails or domains. When a blocked user tries to register on your website, they will also see a custom notification.
This is an example of what the message can look like when a user tries to register with a blacklisted domain:

Domain/Email/IP Restrictions
The next 3 tabs we will consider are Domain Whitelist, Email Blacklist and IP Whitelist.
Each tab has its own form where you can add one domain, email address or IP at a time.
Domain Whitelist
In the Domain Whitelist tab, you can choose to limit registration to email addresses from within your own organisation or company. All other email addresses will be rejected.
Email Blacklist
In the Email Blacklist tab, you can add a list of email which are not allowed to register on your site.
IP Whitelist
In the IP Whitelist tab, you can add a list of IP addresses which are allowed to register on your site. Attempts to register from other IPs will be rejected.
Actions
Once you have a list of entries, you can easily edit or delete them by selecting the corresponding Actions link:
Free Domains
Under the Free Domains tab, you will find a list of over two thousand domains that provide email addresses and that are known for sending spam.
At the top of the page you can see when the list was last updated, and you can check if there are any new updates by selecting the Update Free domain list button:
If you need to check if a domain is on this list, continue to the Tester tab.
Labels
This is the tab where you can customize the text that is shown to visitors when they try to register on your website:
Tester
