WordPress Blacklist Plugin
The WordPress Blacklist plugin safeguards your WordPress site by prohibiting users from registering, posting comments, or submitting forms using banned domains and email addresses.
By using this WordPress anti-spam plugin you can minimize unwanted disturbances by limiting posting access to users with approved emails and domains only. It allows the application of automatically updated domain lists or manual blocking for even more effective control.
Protect your website from spam, malware, viruses, disposable emails, and undesired users for enhanced online security by installing and activating our WordPress blacklist plugin!
Restrict Site Registrations
|
Our WordPress blacklist plugin allows only users with authorized domains or certified email addresses to register and utilize your WordPress site. It makes it easy to avoid unwanted spammers, viruses, and malware with one-click blacklisting. The WordPress blacklist plugin can function in whitelist mode as well, restricting site registration to only approved domains or specified email lists. |

Blocking Registration Attempts
Error Log Report Showing All Blocked Registrations |
Our blacklist plugin will automatically verify user registration attempts, comments, or form submissions on your WordPress site against the blacklist function or specified records of blacklisted or whitelisted domains and put them in the logs for you to analyze. It filters and categorizes users based on their domain, email, and IP, allowing you to effectively manage and control access to your WordPress site. |
Filtering Multiple Domains
|
Our plugin provides you with real time assistance in managing blacklisted domains. It uses several online methods as well as local plugin lists to detect whether a domain is blacklisted or not. This proactive approach ensures that hackers and spammers face significant challenges in registering and posing a threat to your website's security! This is achieved using the following banned domains detector online services:
|
Free Domains List |
Blacklisting Domains
Domain Blacklist |
Utilize the block domain registration to avoid users from unwanted or suspicious sources. This functionality ensures that any emails originating from these designated domains or listed email addresses will be promptly blocked, providing an additional layer of protection against potential threats and ensuring a safer online environment for your WordPress site. |
Creating Email Blacklist
|
Add specific emails to the blacklist to block certain users. People using these emails will not be allowed to register, post comments or fill up forms even if their domain is added to the domain whitelist. |
Email Blacklist |
Gmail Variations Support
Example of Blocking Gmail Variations |
Google allows its users to modify the email address by including dots or plus inside the address. This applies to @gmail.com and @googlemail.com accounts. With the restrict email domains functionality you’ll be able to verify these email variations by adding to the blacklist just a 'clean' version of the email. |
Whitelisting Domains
|
Add domains to the whitelist to allow emails with certain domains to register, post comments or fill up forms on your site. It can be useful if you enable DNSBL Domain and Free Domain lists. You can also allow users ONLY with whitelisted email domains. |
Domain Whitelist |
Whitelisting Emails
Email Whitelist |
Include email addresses in the whitelist to grant them permission for registration, commenting, or form submissions on your site. These emails remain usable on your website, even if their associated domains are included in the domain blacklist. Additionally, you have the option to permit access exclusively to users with whitelisted email addresses. |
Blacklisting Users Based on IP
|
Add IPs to the blacklist to avoid users from unwanted IPs. Registration attempts from blacklisted IPs will be rejected. Additionally, you have the option to utilize wildcards to define a range of IP addresses for inclusion in the blacklist. |
IP Blacklist |
Adding IPs to the Whitelist
IP Whitelist |
Add IPs to the whitelist to allow users from those IPs to register on your site. Limiting registration exclusively to whitelisted IPs is an option. Utilizing wildcards allows you to define a range of IP addresses to be included in the whitelist. |
Restricting Comments
|
Block the ability to leave comments for guest users. Our blacklist WordPress plugin gives you the ability to create global settings for white/blacklisted domains and emails, as well as establish a distinct whitelist of permitted domains to filter comments from non-registered users on your website. |
Comments Allowed Domains |
Integration With Contact Form 7
Example of Using Blacklisted Email In the Form |
The WordPress blacklist plugin supports integration with the Contact Form 7 plugin. It allows to filter emails which users enter in the custom form, based on your white and blacklists for domains and emails, including DNSBL and Free Domain Lists. |
Integration With ChatGPT
|
The plugin integrates with ChatGPT to check whether the first name, last name, and email domain provided during registration look like real ones. This helps prevent registrations that use random characters or obviously fake information. By analyzing the submitted data, the system can block suspicious or low-quality registration attempts. This contributes to maintaining a clean and reliable user database while reducing spam and bot activity. |
Example of Checking Fake Data |

Customer Reviews for Email Blacklist
| The Most Robust Solution
CM’s Email Blacklist was the most robust solution out of all of them in the market, so that’s the one I chose. It’s a ‘world of difference’ fewer spammers than we had before installing the plugin. |
| Killed All Spammers
This plugin works as expected; killed all spammers and false/disposable email addresses which is what I needed for years! No more spammers – wonderful!. |
- Works well
Started getting bot registrations so installed to block signups from a specific domain. It works and the list of already blocked domains is very big, all temps emails or spam emails.
- No more spammers – wonderful!

- Perfect and easy
Thanks!
- My site is much safer!
The preemptive domain check is a must for any serious registration system. This was the best solution I could find and it works really well
- Perfect plugin to block disposable (but not only) email
I sent an email asking to modify the plugin to be compatible with my registration form and the team, really very responsive, did it in a few days.
Then I uploaded a file with more than 22000 disposable email domains to block them in my users registration page. The plugins works perfectly without slowing down the registration process
