Want to automatically grow your Campaign Monitor mailing lists when users submit your forms? With the Campaign Monitor addon for WPForms, you can easily create a new subscriber each time a user submits a form on your WordPress site.

This tutorial will show you how to install and use the Campaign Monitor addon for WPForms.


Before you get started, be sure to install and activate the WPForms plugin. Then verify your license and install and activate the Campaign Monitor addon.

1. Connecting Your Campaign Monitor Account to WPForms

Once the Campaign Monitor addon is installed, the next step is to integrate your site with your Campaign Monitor account. To do so, you’ll need to go to WPForms » Settings and click on the Integrations tab.

On the next screen, expand the Campaign Monitor section, then click Add New Account.

To locate the details you need for these fields, log in to your Campaign Monitor account. We recommend opening this in a new browser tab or window as you’ll need to flip back to your WordPress site again soon.

After logging in to Campaign Monitor, hover over your profile name in the upper right corner to view the menu. Then click Account Settings.

Opening the Campaign Monitor account settings

From the list on the following page, select API Keys.

2. Adding Campaign Monitor Integration to Your Forms

Next, you’ll need to connect Campaign Monitor to a specific form to send user data to your Campaign Monitor account. First, create a new form or edit an existing one to open the form builder.

Then go to Marketing » Campaign Monitor and click on the Add New Connection button.

Once the connection is created, choose the account you connected in your WPForms settings from the Select Account dropdown.

Then you can connect this form to a specific list from your Campaign Monitor account using the Select List dropdown.

Note: In order for subscribers to be sent to your Campaign Monitor list, be sure to connect the Email field.

Make sure to save your form once you’ve finished connecting it to Campaign Monitor.

3. Enabling Conditional Logic (Optional)

Conditional logic lets you set rules for events based on users’ selections in their form entries.

As an example, we’ll use conditional logic to let users choose if they want to be added to our Campaign Monitor email list. First, we’ll add a Checkboxes field to our form and change the label to, “Would you like to join our mailing list?”

We’ll add 2 choices to the Checkboxes field and label them, “Yes, sign me up!” and “No thanks, not now.”

Then we’ll go back to Marketing » Campaign Monitor and toggle on the Enable Conditional Logic option.

Once we save our form, users will only be added to our Campaign Monitor mailing list if they select the choice labeled “Yes, sign me up!” from the Checkboxes field.

That’s it! You can now grow your Campaign Monitor mailing list with each form submission.
