Configuring the plugin

After you install the MailChimp for WordPress plugin, you're ready to integrate subscription options with your site. There are two ways to do this:

  • Check boxes: You can add subscription check boxes to comment and registration forms. For example, the comment section of your posts can have a check box that says “Sign me up for your newsletter!”.
  • Forms: You can add a subscription form to pages and posts. For example, readers can submit their e-mail address and then click “Sign up”.

Method #2: Add HTML form code to a widget

If you don't want the extra overhead of a plugin on your WordPress site, you can manually add HTML form code to a widget. The HTML code contains all you need to add a subscription form to your WordPress site's sidebar.

To do this, follow these steps:

  1. Log in to your MailChimp account.
  2. On the top menu bar, click Lists.
  3. Locate the list for which you want to add a signup form, and then click the MailChimp - List options icon icon.
  4. Click Signup forms. A list of available forms appears.
  5. Next to Embedded forms, click Select.
  6. Under Embedded forms, select the tab for the overall style you want for the form, such as Classic or Super Slim.
  7. Under Form options, select the options and fields you want to appear in the form.
    As you make changes, the Preview area dynamically updates what the form will look like.
  8. When you are done making changes to the form, in the Copy/paste onto your site text box, copy the entire block of HTML code.
  9. Log in to WordPress as the administrator.
  10. In the left pane, click Appearance, and then click Widgets. The Widgets page appears.
  11. Drag a Text widget from the Available Widgets section over to the Widget Area section.
    You can rearrange the order of widgets in the sidebar. To do this, drag and drop a widget within the Widget Area section to its new position.
  12. In the Title text box, you can add a title to the form, or leave it blank.
  13. In the Content text box, paste the HTML code that you copied in step 8.
  14. Click Save. The signup form appears in your site's sidebar immediately.
