A man has a great idea to boost form completion rates

You’ve built the form. You’ve shared the link. You’ve waited. And… crickets.

Sound familiar?

Online forms don’t work unless people actually complete them. And while there are dozens of factors that can affect completion rates, a few smart changes can make a big difference—without a full redesign.

Here are three quick wins that can boost form completions fast.


🔁 1. Prefilled forms = Less work, more submissions

No one likes filling out the same info over and over.

With PlatoForms, you can send users a form that already has their name, email, or other details filled in—so they just review and hit submit.

Example: A returning client clicks your link and sees their info already there. No typing, no hassle. Done in seconds.

What you can do with prefill:

  • Fill forms using data from a previous submission or your CRM
  • Hide or lock certain fields (like ID numbers or account info)
  • Personalize the form based on the user

💡 Tip: Combine prefill with conditional logic to skip irrelevant questions.

⏰ 2. Don’t be afraid to remind them

Sometimes people just forget.

If someone opens your form but doesn’t finish it, a polite follow-up can bring them back—especially if it arrives at the right time.

With PlatoForms Reminders, you can:

  • Automatically send a reminder email if a form is left incomplete
  • Set the exact number of hours or days before nudging them
  • Customize the email message to feel helpful, not spammy

Example: “Hey {{name}}, just a quick nudge—your form is almost done! Need help finishing it?”

It’s a simple step that often results in a big bump in completions.


📱 3. Make sure your form works on phones (Really works)

Most people open links from their phones. If your form loads slowly, looks weird, or is hard to tap through, users won’t stick around.

Responsive design isn’t a bonus anymore—it’s required.

With PlatoForms:

  • All forms are mobile-responsive by default
  • You can preview your form on a phone layout before publishing
  • Features like dropdowns, auto-complete fields, and big buttons make mobile filling a breeze

Quick fix: Try your form on your own phone right now. If it frustrates you, it’s frustrating your users too.


Recap: 3 Tweaks that drive more form completions

✅ Use prefilled fields so users don’t have to start from scratch
✅ Set gentle reminders to catch people who forget
✅ Make your form mobile-friendly so they can finish it on the go
