WordPress Plugin: Contact Coldform

[ Image: Coldform Icon ] Welcome to the homepage for Contact Coldform, a secure, lightweight, flexible contact form with plenty of options and squeaky clean markup. Coldform blocks spam while making it easy for your visitors to contact you from your WordPress-powered website. The comprehensive Settings Page makes it easy to take full control with plenty of options and several built-in themes for styling the form. Coldform delivers everything you need and nothing you don’t — no frills, no gimmicks, just pure contact-form satisfaction. Now available at the WP Plugin Directory!


Contact Coldform had a good run (10 years!), but it’s time for something far better: Contact Form X. CFX is superior to Contact Coldform in every way. Contact Form X gives you all the same features of Contact Coldform, plus you also get a recent-email dashboard widget, GDPR options, inline docs, Google reCaptcha, and of course the contact form itself is all Ajax-powered and super awesome.

Contact Coldform = 2008–2018.
Contact Form X = 2018 & beyond..

I encourage all users of Contact Coldform to upgrade Contact Coldform to Contact Form X. You can learn more and download the plugin at the WP Plugin Directory. And yes, I use Contact Form X for my own contact form here at Perishable Press. </update>

As explained at the beginning of this post, I am retiring Contact Coldform. The plugin will be updated through 2018 or so, and will encourage all Coldform users to upgrade to the far superior Contact Form X. Check it out and download via the Plugin Directory:

    Very useful word press plugins for contact Coldform coding..Great sharing..Thanks for demonstration and how to download everything detailed manner..Useful posting

  2. Coldform is wonderful, because of its beauty. I have a problem to use coldform on my site, the contact form page isn’t showed properly. I would like to use Coldform as styled at Perishable Press. Would you tell me how to fix this?

  3. Thank you for this nice plugin. It is easy customisable to my needs.
    I encounter one problem though: if I test it and submit a form including a CC, only the CC arrives on my end. Any Idea how to fix this?

  4. One more thing: the only thing of the form that needs to be translated in the php file is “submit”. Maybe that could also be done in the frontside?

  5. My hosting provider solved my problem. Something was wrong on his side so now all is working.

    Hi Erik, glad to hear you got it working, and thank you for posting the follow-up :)

  7. Please is it possible that your form outputs plain text and not html? If yes how ?
    many thanks.

  8. Hi,

    Great plugin and I have put it on many sites, but recently a friend is having trouble with it on wordpress’ own theme Twenty Ten.

    I swap themes and your plugin works.

    The text isn’t displaying.

    I’ve left the page visible for you so you can see it’s source code if you wish.

    Any ideas?


  9. Regarding my last comment …. it helps to put your Coldskins in the PROPER stylesheet and not the RTL stylesheet.

    Hope people find this useful.


  10. I just installed WordPress on a new site and this was the very first plug-in I installed before ANY editing or posts content, etc. And I get this error. “The plugin does not have a valid header.” When I click on activate plugin.

    I am using WordPress 3.1.

    @rzul: Which version of the plugin are you using?
