in Training

Integrate the optincrusher web form with the MailChimp service to build an optin email list fast. Copy and paste instructions get you going in no time at all.

Hi there,

I have been looking for something like this for a while, tried a coupla things but like yours.

I have a bit of an isse with data not saving on the options page.

to change any of the images or the background I have to input the paths by hand and then it will save. If i click on the images and click save it doesn’t save the changes.
I also have a similar issue with integrating the mailchimp code. after adding the code and clicking proceed it merely refreshes the page and clears the box of the code?

Is this likely to be a permissions solution? or are ther any known conflicts with other plugins, for instance I am running analytics 360 with the mailchimp integration option – I know that this is likely to cause problems with some plugins?

Discovered my own answer. It doesn’t like you using chrome!! I have a couple of php scripts just like it. No matter how hard you try nothing happens if you use chrome, but are fine in Explorer9, which is curious as they are all Mozilla/Firefox based!!

love the plugin – knocks spots off the others!

Thanks for the report Jameson. I’ll have a look at chrome/mailchimp at some point. I know that aweber+chrome works, but that doesn’t help much with mailchimp.

Hi Daniel,

Thanks for the video. One little problem, MailChimp has completely changed their design page and I’m having difficulty figuring how exactly how to get the code I need to implement the plugin. I don’t know if you have time to take another look at it, but updated instructions would be awesome.

I’ll have to double check mailchimp. It’s been over a year and I’m sure things have changed a bit.

In the meantime, you can manually prepare the optin form and paste it in. It’s a bit more work, but will get you up and running with optincrusher quickly.

Hi Daniel,

I can get the code but the form is placing the “SUBSCRIBE” button below the email address box, which means it’s half off the screen.

What do I need to do to get the subscribe button to appear beside the email address box?


Daniel June 11, 2012 at 7:56 pm

You need to make sure the submit button is not an image. If it’s a submit button with no inline styles, the default installation should work.


Bill June 11, 2012 at 9:18 pm

How do I do that Daniel? I assume I have to delete some part of the code below but when I tried removing the entire line below the form had no SUBMIT button at all.

Thanks very much for your help with this.


Daniel June 11, 2012 at 9:20 pm

You just need to end up with something like this inside the angled brackets:

input type=”submit” value=”Sign Up”


Yolanda February 19, 2013 at 12:56 pm

I hate to come almost 8 months later about the same topic. I am confused as to where the above input line should go and what information I should be replacing it with to have the email sign up line in the correct location for mail chimp. If you visit my site you will see that the line is buried. Thanks for any help 🙂


Daniel February 19, 2013 at 9:10 pm

In this case you just need to tweak the CSS a bit. I prefer to use Chrome developer tools for that.


Brett March 22, 2013 at 2:16 pm

Daniel, I have similar issues as Bill and Yolanda.. The subscribe button overlaps the email box on the footer, and it’s on the side of the email box on optin light box.

Here’s the snippet of code pertaining to the subscribe button:

I revised the code above to: input type=”submit” value=”subscribe” But it didn’t fix it.

I’m no techie, so any step-by-step instruction on how to correct this will be helpful.

Sorry for the long message.

Thanks for your help.


Daniel March 30, 2013 at 5:15 pm

Brett, the code doesn’t come through in the comments. As long as you’re not using an image for your submit button, the only other thing to consider is CSS. In most cases the CSS for optincrusher is well isolated. Occasionally you have to make a change to the CSS for your overall theme or choose a different theme.


Daniel May 23, 2013 at 7:28 am


Thanks for the plugin, but unfortunately the instructions on this page in reference to Bill’s comments are not very helpful; I have the same issues with the email field and subscribe button being pushed down.
Mail Chimp now gives three different options for the embed form: Super Slim, Classic, and Naked. Can you please provide us all who prefer MailChimp detailed instruction as to which of the three options to choose, what to select, and how we must edit the code. Please remember most WordPress users are not code-savvy and you’ll have to talk to us like we are four years old. I have about 5 other websites that I’d like to put this on so I need to understand the bugs before giving it to clients. (FYI, I’ll have to deactivate the plugin as my site is live.)


Paul July 25, 2013 at 1:42 pm

Wow, you’re a piece of work. This is free. If you want help for commercial endeavours, try hiring him. If not, don’t tell us you have 5 other websites, for what?

Create a thank you page and use the shortcode to prevent the optincrusher from showing again.


Bethany August 24, 2014 at 5:31 pm

Hello! Thanks for the awesome plugin!

I’m having a problem though – even though I have inputted my opt-in code from Mailchimp and did the “process form” thing within wordpress (and I did see output in that second box) I still don’t see an opt-in on the bar. I see the red arrow, and I was able to customize the graphics fine, but the opt-in is missing. I even tried to use another version of the form from mailchimp – tried all three forms they have, in fact, with the same result. Am I missing something?


Kirk Ream February 20, 2015 at 4:39 pm

Does this plugin also work on mobile devices? For some reason it is not popping up on my responsive website


Rashid Rupani February 21, 2015 at 10:48 am

Currently, It doesn’t work on Mobile devices…


Justin February 23, 2017 at 4:55 pm

Really like the plug-in and the possibilities that it offers. Is there a responsive / mobile friendly version available or in the works?


Daniel February 25, 2017 at 8:03 am

Justin, it’s in the works, but slowly. I don’t have a release date, but if you stay on my list, you’ll get the notification.


B. Simon April 11, 2017 at 4:55 am

tried several times to add the mailchimp connections. The code does not seems to work for me. not sure what is happening. I followed the direction to the teeth and what is happening is that i paste the code as instructed in your tutorial, press the green button to generate optincrusher code, nothing happens and the code will disappear. Any thoughts why this may be happening? I did not think i needed to install mailchimp plugin on the site, but i went ahead and did it anywhere just in case it was needed. Still did not work.

Thanks for getting back with me me on this.


Daniel April 12, 2017 at 7:46 pm

Unfortunately this tutorial is a bit dated. The important part is that you have a raw HTML form. As long as you have that, it should work.


Paddy July 28, 2018 at 11:04 am


This might be an obvious question but I cannot see where I would specify the download file I wish to provide to my subscribers once they have clicked on the subscribe option and entered their email address? I want them to be presented with a download eBook option, any help would be much appreciated.
