Step 2: Set up & Configure MailPoet for API Key
To connect your popup forms with MailPoet, you need to configure MailPoet correctly and ensure API access is enabled.
Here’s how:
Open MailPoet and continue the setup.


Next, you’ll be redirected to the Privacy and Data Settings page. Review the policies carefully, then click the “Continue” button to proceed.


You will be prompted to connect your MailPoet account. Click “Connect MailPoet” to be taken to the setup page. From there, you can log in with your existing credentials or create a new account if you don’t have one yet.


After setting up your MailPoet account, you will be given your API key, as shown in the image below. Copy the key and return to your WordPress dashboard.


At this stage, you should enter your API key in the MailPoet plugin settings. Paste the copied key into the required field and click the “Verify Account” button.


Once the verification is successful, click on “Start using Mailpoet.” And that’s it! Your MailPoet account will be ready to use.


Once connected successfully, your popup plugin should be able to access your MailPoet subscriber lists.
Step 3: Enable MailPoet in PopupKit Settings
Now it’s time to connect PopupKit with MailPoet. To do that, open your WordPress dashboard and navigate to PopupKit → Integrations.


Next, locate MailPoet from the available integrations list and click on the manage button. You will be prompted to enter your MailPoet account name.


Click on the Connect MailPoet Integration button.
After enabling the integration, PopupKit should sync with your available MailPoet email lists automatically.
This connection allows subscriber information collected through popup forms to be sent directly into MailPoet.
Step 4: Configure MailPoet in the PopupKit Editor
Once the integration is active, you can configure individual popup forms.
To do this, go to PopupKit → Create Popup → choose a popup template or create one from scratch. You can also open an existing popup campaign. But in this tutorial, we’ll make use of our existing campaign.
Once opened in the editor canvas, click on the form block for you to select the integration.


Next, click on the integration and select MailPoet from the dropdown. Then select your provider account and the provider lists where new contacts should be added.


Step 5: Publish and Test the Popup
Before going live, always test your popup integration. Start by publishing the popup and then open your website in an incognito browser window. Manually trigger the popup, submit a test email address, and confirm that the subscriber appears in your MailPoet list.
In addition, test the popup’s mobile responsiveness, timing settings, form validation, and confirmation email delivery. Testing ensures your integration works properly and helps avoid losing potential subscribers due to technical issues.
