Best practices for interactive forms

Here you will find our guidelines on creating effective interactive forms that both maximize engagement and ensure reliable delivery.

​
Limit the Number of Questions

We recommend keeping your forms concise and focused:
  • Start small and test your form before adding more questions
    • Begin with around 3-4 questions per form to see what resonates with your audience and avoid overwhelming them
  • Longer forms (10+ questions) tend to see significant drop-off rates
  • Each additional question reduces completion likelihood

​
Use Easy First Questions

The first question sets the tone for engagement:
  • Avoid starting with open text input fields - they create a higher barrier to entry
  • Begin with choice questions or NPS ratings that require just a click
  • Once users click and see the email is interactive, they’re much more likely to continue engaging
This approach makes the initial interaction effortless for the user and demonstrates the interactive nature immediately.

​
Use Pages

Multi-page forms improve the user experience and enhance data collection:
  • Collect partial responses in AMP and Apple Mail (default for all Pro plans)
    • Answers are stored when the user navigates to new pages, allowing you to collect data even if they do not fully complete the form
  • We recommend using 1 question per page for simple forms such as preference surveys
  • Splitting forms into pages can help to:
    • Keep emails shorter and reduce scrolling
    • Create a cleaner, less cluttered appearance
    • Reduce hesitancy / friction to begin your form

​
Enable Fluid Mode

For single-question-per-page forms, turn on Fluid Mode to auto-advance users to the next question as soon as they make a selection — removing the need to click Next after each answer.
  • Reduces clicks and friction, leading to higher completion rates
  • Answers are still saved to the Klaviyo profile in real time, so partial submissions are preserved
  • On pages with multiple questions, Fluid Mode automatically defers to a manual Next click so users can answer every field
Toggle it under the form’s Settings → Email → Advanced menu. See the full setting reference in Form Elements & Settings.

​
Communicate Interactivity Clearly

Help users understand they can interact directly in the email:
  • Keep in mind that many subscribers have never received an interactive email before
  • We provide an Interactivity Indicator (enabled by default) that displays a small animated gif to indicate the form’s interactivity.
    • We recommend leaving this enabled
  • Consider adding instructional text when fitting, such as:
    • “Click below to respond directly in this email”
    • “This form works inside your email”
Clear communication encourages participation by setting proper expectations and reducing friction.

​
Additional Tips

  • Test your forms thoroughly across different email clients

  • Monitor analytics regularly to optimize question types and order
  • Consider your audience’s context when timing form deployment
  • A/B test different question formats to maximize engagement
    • Create two versions of your form to test the best fit for your audience. Consider testing:
      • Amount of questions
      • Question type (e.g. image selection vs. choice buttons, free text input vs. choice)
      • Wording
    • Check the analytics for your different forms in the Kinetic dashboard to determine which is converting better. More details on our analytics dashboard can be found here.
