Since the Anti-Spam version 5.177, we’ve added a new feature. Now you can encode all email addresses on your pages. Email characters will be hidden visually and addresses will be encoded, so the automatic crawlers will not be able to grab addresses. Visitors can decode addresses by mouse click. This feature helps to prevent direct spam to your email. You can enable this option in the Data Processing section here:

WordPress Dashboard → Settings → Anti-Spam by Cleantalk → Advanced settings

Encode contact data option

The plugin will encode all email addresses on your pages.

Encoded view:

After clicking the address will be decoded:

That’s really how it works. Give it a try and protect all your email addresses on the website.

 

How to check the encryption already works

  1. Open your webpage in your browser Guest (Incognito) mode.
  2. Scroll down the page to the email address. Now you should see the email is already encrypted.

To decrypt it, just click on it. If you hover the mouse pointer over the email, you will see the “This contact was encoded by CleanTalk. Click to decode” message. It is a hint for your website visitors. Be sure to test the encryption/decryption in Guest (Incognito) mode, because if you are authorized on the site, there will be no encryption.

Encrypted view (Incognito mode) Decrypted view (or authorized)

Since version 5.184 of the Anti-Spam plugin, each email encoding is logged in your Anti-Spam Log with the status “Decoding approved”.

Feel free to ask your questions in the comments below or email us at welcome@cleantalk.org 🙂 If you see the email address in full, you probably didn’t switch to incognito mode in your browser.

    Hey,
    This is a great option, much appreciated!
    Question: Is it functioning on pages only? I just enabled it on a client site but on this particular site the contact details are only viewable on posts & I can see no change to the information.
    Many thanks,
    Susan

    The “Encode contact data” option works with emails in Posts.

    I remember these encryption schemes from many, many years ago. I normally use web mail. I clicked on the we*****@cl*******.org on this page. My Outlook opened and placed we*****@cl*******.org in the To field – asterisks and all. Too bad there wasn’t a way to implement this via coding that didn’t require JavaScript enabled on the site visitor’s device. I am noticing more am more folks not enabling it.

      Hi Charles,

      Thanks for the great feedback! It was an issue with plugin settings on our blog. I’ve changed the settings and now the decoding is working as it should be.

      JavaScript is required because it’s part of the technology of encoding contact data. I hope if you test again, you will find that it goes perfect.

      Let me know if you have any questions.

    I tried, you say “WordPress Dashboard → Settings → Anti-Spam by Cleantalk → Advanced settings”, but when I go on the settings of my dashboard,, there is no “Anti-Spam by Cleantalk”, nor “Advanced settings”. Any clue?

    Just wondering if this encodes an email address in a mailto link on an image for example?
