How to Connect Popup Builder & Popup Maker for WordPress – OptinMonster to Services Without a Direct Integration

Many users of the Popup Builder & Popup Maker for WordPress – OptinMonster Email Marketing and Lead Generation plugin want to connect their popups to email marketing services or CRMs that don't have a pre-built, native integration. This is a common scenario, especially with newer or more niche platforms.

Fortunately, the plugin offers several flexible methods to send lead data to virtually any third-party service, even without a dedicated integration. This guide will walk you through the most common and effective solutions.

Why Direct Integrations Aren't Always Available

The development team for Popup Builder & Popup Maker for WordPress – OptinMonster Email Marketing and Lead Generation maintains a large number of native integrations for popular services. However, it's not feasible for them to build and support a direct connection for every single platform on the market. When a user requests a connection for a service like Sendy or HighLevel, the team often adds it as a feature request for future consideration, but a native solution is not guaranteed.

Solution 1: Use the Embed Form Block

This is often the recommended first approach. Many email service providers (ESPs) give you a snippet of custom HTML code for their signup forms. You can use this code within OptinMonster to create a connected form.

1. Obtain the raw HTML form code from your email marketing service or CRM (e.g., Sendy, HighLevel).
2. In the OptinMonster campaign editor, add an 'Embed Form' block to your popup.
3. Paste the complete HTML form code you obtained from your ESP into this block.
4. Save and publish your campaign. Leads captured by this form will be sent directly to your service, bypassing the need for an OptinMonster-native integration.

This method works because the form submits data directly from your website to your ESP's endpoint.

Solution 2: Utilize the Webhook Integration

Webhooks are a powerful and universal way to connect applications. If your third-party service (like Make.com) can provide a webhook URL to receive data, you can use OptinMonster's built-in webhook feature.

1. Locate the webhook URL in the service you want to connect to. This is often found in automation or integration settings.
2. In your OptinMonster campaign settings, navigate to the Integrations tab.
3. Click Add New Integration and select Webhook.
4. Paste your webhook URL into the provided field.
5. Map the data fields (e.g., {{email}}, {{name}}) to the expected format of your receiving service.
6. Save the integration and publish your campaign. Now, when a lead submits the form, their data will be sent to your specified webhook URL.

Solution 3: Leverage the API with an Automation Tool

For advanced users or when connecting to complex automation platforms like Make.com or Zapier, you can use OptinMonster's API.

1. Generate an API key from your OptinMonster account page.
2. Use this key to authenticate requests from an automation platform (e.g., Make.com, Zapier) to the OptinMonster API.
3. Within your automation tool, you can build a scenario that triggers when a new lead is captured. The tool can then fetch that lead's data via the API and perform an action, such as adding it to your CRM.

This method offers the most flexibility but requires configuration within a third-party automation service.

By using one of these three methods—the Embed Form block, Webhook integration, or the API—you can successfully connect your OptinMonster popups to almost any email marketing or CRM platform, even without an official native integration.
