Add Opt-In Forms to WordPress is easier than most bloggers and business owners think. In just 15 minutes, you can create fully functional opt-in forms and start capturing subscribers without any coding knowledge.
Email opt-in forms may seem like they appear magically, but there’s a clear process behind them. In this tutorial, I’ll show you exactly how to add opt-in forms to WordPress using Drip so you can grow your email list on autopilot and stop losing subscribers.
Types of Opt-In Forms in WordPress

When you want to add opt-in forms to WordPress, it’s important to understand the different display options available. You can choose from pop-up forms that grab attention immediately, embedded forms that sit seamlessly within your blog posts or pages, or—in Drip’s case—slide-out forms that gently appear from the side as readers engage with your content. All of these options work well with WordPress, but keep in mind that free WordPress plans may make integrating Drip slightly more challenging.
Choosing the right display method is crucial for conversions. Pop-up forms are effective for urgent calls-to-action, like newsletter sign-ups or lead magnet downloads. Embedded forms are perfect for readers who are already engaged with your content and prefer a non-intrusive experience. Slide-out forms, available through Drip, strike a balance by staying visible without disrupting the reader’s journey. Understanding these differences will help you maximize the performance of your optinforms to WordPress.
The email marketing provider I personally recommend—and use—is Drip. It integrates smoothly with WordPress, offers advanced segmentation, and provides detailed analytics so you can track the performance of your forms. Using Drip makes it easy to add opt-in forms to WordPress without requiring custom coding or technical expertise.
To get started, create a new form in Drip. Give your form a descriptive name, such as “Test Form,” and assign a relevant tag. Tags help you identify where your subscribers are coming from, like Blog_Visit for general blog readers or FreeGuide_Download for people downloading a resource. Proper tagging ensures that your optinforms to WordPress campaigns remain organized and highly effective, letting you segment your audience and send targeted follow-up emails based on their interests.
By understanding your display options, choosing the right email provider, and carefully tagging subscribers, you can effectively add opt-in forms to WordPress that convert visitors into loyal subscribers. This step is the foundation for growing a responsive email list and improving overall engagement on your WordPress site.
Different Types of Drip Forms
- Exit-Intent Popup – appears when a visitor is about to leave your site.
- Slide-In Form – shows up as a side tab without interrupting the reading flow.
- Embedded HTML Form – sits inside a blog post, page, or sidebar.
After choosing your preferred form type, click “Create Form” to move to the customization stage. Then select which fields to collect (name, email, etc.) and start customizing the form to fit your brand.

Designing Your Opt-In Form
Designing your optinforms to WordPress is simple with Drip. You can customize every element of your form to match your brand, including colors, fonts, text, and layout. Choosing the right colors and font sizes helps make your form more visually appealing and increases the likelihood that visitors will subscribe.
In addition, you can upload an image to your form—ideally 300px wide by 450px tall—which draws attention and enhances the overall design. A well-designed image can make your opt-in forms to WordPress stand out and communicate the value of your offer instantly. Using Drip’s intuitive interface, you can also rearrange form fields, add compelling headlines, and include descriptive text to guide visitors toward subscribing.
By thoughtfully designing your forms and including key elements, you can create add opt-in forms to WordPress that not only look professional but also convert more visitors into subscribers. Remember, the better your form looks and communicates value, the more successful your email marketing efforts will be.

When Should the Form Appear?
Timing is critical for conversions. Drip gives you complete control over when your opt-in forms appear so you can maximize engagement without annoying visitors.
- After a set time delay: Show the form after a visitor has been on the page for a set number of seconds.
- After scrolling to a certain point: Trigger the form once a visitor scrolls down a portion of your content.
- When clicking a button or link: Open the form via a “Subscribe Now” button or link, reducing disruption.
- Through the JS API (advanced users): Full customization for developers using Drip’s JavaScript API.
Testing different triggers is key. By carefully timing your form, you improve the user experience and increase subscriber conversion rates. Track your results with Drip’s opt-in forms.
What Happens After Submission?
Once someone opts in, decide the next action: redirect to a thank-you page, deliver a lead magnet, or add subscribers to a Drip automation workflow. From there, the sky’s the limit for engaging your audience.
And that’s it! Adding opt-in forms to WordPress is fast, easy, and highly effective. With Drip, you’ll start collecting subscribers in minutes and growing your email list faster than ever.
