Form Types and When to Use Them

Brew offers three different form styles, each suited for different situations:

Inline Form

Embeds directly within your content. Ideal for dedicated newsletter pages or blog post footers.

Popup Form

Appears as a popup overlay. Great for capturing attention when visitors first arrive or are about to leave.

Floating Form

Stays fixed in the bottom corner of the screen. Perfect for non-intrusive, persistent sign-up options.

​
Creating Custom Forms (Advanced)

If you need more control over your form’s appearance or behavior, you can create a custom form that submits to Brew’s API: 
<form action="https://app.getbrew.ai/api/v1/forms/submit" method="post">
  <input type="email" name="email" required placeholder="Your email address">
  <input type="text" name="firstName" placeholder="First name">
  <input type="hidden" name="source" value="custom-landing-page">
  <input type="hidden" name="subscriptionGroups" value="sg12345,sg67890">
  <button type="submit">Subscribe</button>
</form>

Form Best Practices

​
Managing Form Submissions

After setting up your form, you can track submissions and performance:
  1. Go to the Forms section in Brew
  2. Select the form you want to view
  3. View submission statistics:
    • Total submissions
    • Conversion rate (if tracking views)
    • Submission trends over time
To troubleshoot a form that’s not working, check your website’s JavaScript console for errors and verify that the form code is correctly installed.
