Implementing the mailchimp form on your WordPress site (Using the Genesis Framework )

  • Navigate to ==> Appearance => Editor from your wordpress admin dashboard => click on function.php
  • Create a backup copy of your function.php and add the code below to the last line of your function.php
/**obasimvilla.com/easily-add-mailchimp-subscription-op-tin-form-to-after-post-content-in-genesis-without-a-plugin */
function add_newsletter_box() {
  require( CHILD_DIR . '/newsletter.php' );
add_action ( 'genesis_after_post_content', 'add_newsletter_box', 10, 1);
  • Click on save to store your new settings
  • Finally you need to add style to your newsletter opt-in form, Just copy the code below and add it to the last line of your style.css or simply paste it in the custom css window (some part in this css are not just useful for  this tutorial alone but also for others who might want to use feedburner instead of Mailchimp)

Concluding Lines on adding mailchimp auto-responder / subscription opt-in form:

For business it is a recommended practice to allow users subscribe to your list instead of forcing it on them. Feed burner is also a great option to use under your post content it is also provided in the css code above . If you want to use only feedburner form you will need replace the newsletter.php with a feedburner uri I will provide to you in the discussion . In just 1 hour after implementing this I have gained 90 subscribers to the list I just created for this . see screenshot below

  1. I am lost after this point -> Copy the generated code and paste it in a text editor (notepad recommended ): I have copied the embed code from my mailchimp account. But i dont get the below and steps after that…
    “Copy only the form action area and post it in an open notepad window taking note of the following parts ; form action=”” , u=”” and id=”” as highlighted in the screenshot below” …
    Would be awesome if you could elaborate. Kinda need the help.

    • Hi Mayur,

      You’ll need extract the only the contents of the [form action=”” , u=”” and id=””] values from the code you’ve copied and substitute same in the code snippet given in this tutorial.

    • adding it to other themes on wordpress doesn’t require any additional configuration . All you need do is ignore the function.php part and copy the content meant for newsletter.php to after content on single.php or simply paste it using your quick adsence plugin

  2. This post is so explanatory. And the option of mail chimp is nice. But, What if I don’t want to touch the style how will the form look like and, can I use the first code for other mailing list provider?

    • without the touching the style your form will still look cool but without the sign-up wrap and box around it . Yes you can use for any other newsletter opt-in form it by replacing those variables

  3. You have said it all. Nice tutorials for newbies and well illustrated with simple english. But my honest opinion is that Mailchimp are kinda wicked or strict with their services. They will just decide to ban accounts for no reason without notification. I think that is cruel act. I prefare listwire anyway.

    • I have really never heard of listwire, just seeing it for the first time now , will consider exploring their services in the future. I always advice persons using a particular service to read through their terms and services ‘cos no sane company will ban rule abiding users

  4. Obasi, thanks for this great post. I have been thinking of how to automatically add a mailchimp subscription form to my posts. I have actually been doing it manually.

    However, at the moment, I would rather have someone handle it for me than play with my files because am not yet grounded in that area of changing or modifying the codes in my functions file. Thanks all the same. It’s such a nice post.
