Powerful as WordPress is, it’s still swarmed with spammers who are trying to look for email address and send spam emails without your permission. One of the ways that they use to do that is by using bots or an email spam domain to crawl on your site and cause serious damages there.
There are a number of tools to restrict spammers, such as security questions, CAPTCHA protection and email confirmation, etc. Among those prevention methods, we suggest using a handy plugin named CryptX to block spam emails. Meanwhile, some alternative options of third-party websites are also included.
How to Block Spam Emails Using CryptX Plugin?
A good practice to block spam emails is by encrypting/hiding your personal email address. Some WordPress users use this anti-spam function introduced from the WordPress Codex to covert every email character into respective HTML entity. This method is useful enough to detect and block spam bots, but you can still rely on this “CryptX” plugin to:
- hide all of your email addresses with or without a mailto-link.
- replace email with PNG image, along with selectable font size and color.

1. Install & Activate CryptX Plugin
To start, just download “CryptX” plugin via the above link and then upload its folder to your /wp-content/plugins/ directory. Once done, log onto WordPress dashboard and activate this plugin through the “Plugins” sidebar menu. As shown, there will be a new “CryptX” label appearing under the “Settings” area.
2. Customize Presentation Settings
Firstly, you will be prompted to define a unique “ID” or “Class” within the blank text field. The default characters for “@” symbol and “.” are [at] and [dot], but you can choose to use custom characters in email address. The other options let you enter URL for image, text for link, title-tag for image and select title-tag from folder.
To have your “Text Scrambled by AntiSpamBot” or “Covert Email to PNG-Image”, just check the radio buttons on the left side. By default, the font size and font color are set to “10” and “000000”. Do remember to save changes after all settings.
3. Make General Settings
Scroll down and decide where you’d like to apply CryptX, such as content, custom fields, excerpt, comments and widgets. Below is the “Excluded IDs” that are usually separated by comma. There are two types of decryptions to hide the email link, and you can choose between
There is an option to embed mailto to all unlinked email addresses, and you’d better think carefully before resetting CryptX options to the defaults. If needed, you can apply CryptX to your template file by pasting the offered configuration code.
