A popup form is a small, interactive web interface element (a modal or overlay) that appears on a webpage and asks users to do a specific action. Its job is simple: catch a visitor's eye before they move on.
Unlike static HTML forms embedded in a footer, a popup form is active and appears exactly when a user is interested or about to leave. This ensures your best offer — like a discount or a newsletter — actually gets seen, turning a fleeting visit into a lasting connection.
Main benefits of popup signup forms for business include:
Looking at recent benchmarks, standard signup forms convert at an average 3.53%, giving brands a steady way to turn browsing traffic into subscribers. But the biggest gains come from execution: the top 1% of signup forms average 27.53% (with some climbing past 55%), and nearly 74% of those high-performing examples are popups.
That’s not by accident. Popups show up when attention is at its peak and focus the visitor on a single action, which makes them far harder to ignore than a static form buried on the page.
Another way to guarantee conversions is gamification — interactive elements drastically outperform static forms.
| Form configuration | Avg. CR | Why it performs this way |
|---|---|---|
| Email only | 2.48% | The basic option with the lowest friction. Ideal for first-time visitors who aren't ready to share personal details yet. |
| Email + Promo code | 3.85% | This form provides immediate value straightaway. This levels the “cost” of typing in an email address. |
| Email + Exit intent + Promo | 5.76% | A behaviour trigger catches visitors at the perfect moment (when they want to leave). Plus, the discount offer doubles the CR compared to standard popups. |
| Gamification + Countdown | 16.13% | When fun meets pressure, users act faster to get the prize (discount). |
| Email + Phone | 1.0% | Asking for a phone number along with an email raises a trust barrier and scares off visitors. It’s better to use a 2-step form to collect email first and then ask for the phone number. |
Here's how to create a popup signup form that provides a discount as a small opt-in incentive for subscribing to your newsletter.
Skip the blank canvas — Claspo gives you access to over 1000 templates with a responsive design. Just pick one that corresponds to your goal, and you’re already halfway there. After choosing a template, swap in your own text and adjust the design to reflect your brand identity.
With Claspo’s drag-and-drop editor, personalizing your widget is easy. Click any element to edit text, adjust fonts, switch up colors, change the background, or restyle the CTA button to match your branding.
The template we’re working with includes an image block. Click on the image to open its settings on the right — upload your own file (PNG, JPEG, WebP, or GIF), or choose from our built-in image library.
This template comes with a text roller component that adds dynamic movement to your message. Double-click to open its settings. In the Style tab, you can update the color, add a stroke, or background. Under Options, enter your custom messages to rotate.

And don’t forget about the confirmation screens — Success, Existing, and Error. You’ll find these at the bottom of the editor. Customize each one so users get a clear, consistent message after submitting their email.
Don’t rush the popup — let users settle in first. To target genuinely engaged visitors, set the widget to appear only after someone has viewed at least three pages. You’ll find this trigger in the settings — just toggle it on.
Want more control? Combine different display triggers like:
You can also define who sees the widget — first-time visitors, returning users, mobile vs. desktop traffic, or people browsing specific pages. This helps you deliver the right message to the right audience at just the right time.

The purpose of popup signup forms is always to collect data (emails or phone numbers, or both), but the format you select determines the user experience. Select your type based on whether you want to be proactive or subtle:
Lightbox popup
This is the classic centered overlay that dims the background content. It is the best option for high-value offers, such as first-order discounts, because it attracts the user's full attention.
Floating
When the user scrolls, a sticky bar remains at the top or bottom of the screen and never blocks content on your website. Mobile users benefit most from it. It’s also great for ongoing announcements.
Floating box
This is usually a widget that slides into the corner (bottom right/left). It uses movement to grab attention without covering the main text, offering a "polite" but effective way to ask for a signup
Content-blocking widget (fullscreen mat)
This is usually a widget that slides into the corner (bottom right/left). It uses movement to grab attention without covering the main text, offering a "polite" but effective way to ask for a signup
Gamified popup
These popup forms use interactive mechanics like "Spin-to-Win" wheels or scratch cards. They boost engagement by turning the signup process into a game.
A well-crafted popup signup form has the following features: relevant design, smart timing, high relevance, and practical value. To increase your CR, you need to create a popup form that feels helpful, not intrusive. Here is a brief checklist with best practices to follow:
1. Time it right with smart triggers
Popup signup forms perform best when they’re timed to match visitor behavior. In most cases, guidelines suggest showing a popup signup form after someone has scrolled up to half of a page, spent 10–15 seconds on-site, or shown signs of exit intent. Treat these as starting points, analyze how users behave on your website, and adjust triggers to your needs.
2. Keep it focused & simple
Too many form fields can scare visitors off. Stick to the essentials — usually just a name and email. A minimalist design keeps the process frictionless and improves the user experience.
3. Highlight a clear value exchange
Don’t just ask visitors to subscribe — give them a reason. Offer a discount, downloadable content, or access to a newsletter, etc. Make the benefit of signing up obvious and valuable. This is what drives lead generation.
4. Use a strong CTA button
Your button copy should be clear and action-oriented. Phrases like “Get My Discount,” “Join the List,” or “Subscribe Now” work better than vague CTAs. Also, make sure the button stands out. For this, use contrasting colors that match your popup’s design.
5. Optimize for mobile
As a rule of thumb, your popup form needs to be fully responsive because the share of users browsing on mobile is always growing. Avoid intrusive layouts that disrupt navigation. For example, use a floating box instead of a popup form. Consider creating a separate campaign to target mobile visitors. Make sure the close button is clearly visible. Also, avoid using large images, or don’t use images at all.
6. Automate the follow-up
The signup is just the beginning, not the end. Connect your popup form to your Email Service Provider (ESP) to trigger an instant welcome flow. This is when you deliver the promised incentive (a discount code or PDF), introduce your brand, and begin segmentation. Tagging users based on where they signed up (e.g., “Blog reader” vs. “Cart abandoner”) allows you to send relevant content that keeps them engaged long-term.
A popup form should be attention-grabbing but on-brand. The widget structure usually looks like this:
Optional modal components: dropdowns for preferences, checkboxes for segmented lists, discounts for additional incentives.
The popup signup form performs best when strategically timed based on visitor behaviors and intent. Popup signup forms are ideal for converting:
Trigger your popup forms when users show engagement: scroll 50% of a page, spend 10–15 seconds on a homepage, landing, product, or blog pages, or show exit intent. A single, well-timed popup works better than several obtrusive ones, so avoid overdoing it. Provide value when the user is ready to receive it.
Our benchmarks show that even a high-value offer can fail if the delivery is wrong. Here’s what to avoid in your popup signup forms to save CR:

Yes, absolutely. Our recent study analyzing 779 million impressions shows that while generic forms average just 1.5–3.5% CR, strategic popups in 2026 consistently hit 10–30% CR. The secret to high rates is timing (smart triggers), how you engage visitors into taking action (gamification mechanics), and how you personalize your offer (matching your offer to the user's actions).
It depends on what you want to achieve. We recommend using a single-step form when you need to collect data fast and want zero friction. When you need detailed information (e.g., during onboarding or feedback collection), launch a multi-step form. It’s easier for users to fill out long forms when there are 2-3 fields on a page.
There are two ways to deliver your lead magnet: either through email (using an ESP integration) or through an instant download link right in the popup form.
To set up an instant download in Claspo:
You can use Claspo’s built-in A/B testing. This feature helps compare different variables on your popup forms, such as a discount offer vs. a freebie for subscription, when you doubt which will convert your audience better.
Here’s what you need to do:
The compliance of your popup signup forms depends on their design and transparency. GDPR/CCPA standards strictly require your form to request explicit consent (no pre-checked boxes) and to include a link to your Privacy Policy. Claspo supports this with drag-and-drop legal components and high-level data encryption. For added security, you can sync with your ESP to enable double opt-in verification.
No, if you use Claspo. We optimized our scripts to load asynchronously, so they don’t slow down or block your main content. Claspo popup forms constantly score a perfect 100 on Google PageSpeed Insights.
Stop bots with a multi-layered strategy. First, enable reCAPTCHA to block scripts and use Claspo’s built-in field validation to rule out any possible errors. Next, enforce double opt-in through your EPS to confirm intent. For B2B funnels, you can even block generic domains (like Gmail or Yahoo) with a single toggle to ensure lead quality.
With Claspo, you can fine-tune exactly when and where your popup form appears. Set triggers based on:
You can also target a specific audience, like mobile or desktop users, new or returning visitors, or even people viewing a specific page. This allows you to easily align your popup form with the visitor’s behavior and intent.
Yes, Claspo is fully compatible with your existing email marketing and CRM tools. The platform supports native integrations and Webhooks. This means that it will be very easy to follow up on the leads you have generated since they will be directly integrated into your workflow.
You can add Claspo widgets to your website by copying and inserting our script, installing a plugin (for WordPress or Shopify), or using Google Tag Manager.
You don’t need to be a programmer to use Claspo. Claspo makes it easy to create an email popup form using its intuitive drag-and-drop editor. The platform offers over 1000 ready-made templates — not just for signups, but for a wide range of goals, including promotions, surveys, announcements, and more.
Claspo provides a suite of advanced components designed to optimize performance. You can dynamically insert user data with merge tags for a tailored experience, or utilize text rollers and countdown timers to command attention and drive immediate action.
Claspo has everything you need, whether you're looking for an eye-catching, interactive widget or a simple, minimalist email capture popup form. Our wide feature set allows you to design a popup signup form that supports the exact objectives you have established for your campaign.
Yes, you can use Claspo for free with its Free Forever plan. The free plan doesn’t limit the builder’s functionality, allows creating unlimited widgets on one website, and lets you manage the project with unlimited team members. The only thing that differs on the pricing plan is the number of the website’s monthly pageviews. If you need more pageviews, you can easily upgrade your plan.
Yes. Across industries, it’s a good practice to create separate popup forms for different devices. You can either create a single responsive widget that automatically adapts to screen size or launch separate campaigns for each device.
Yes, definitely. Not only can you schedule campaigns to run automatically during a set date range, but you can also choose custom days and times. For instance, you can run a “Lucky Wednesdays” promo every week or launch a flash sale from 6 PM – 8 PM. Besides, you can set a specific timezone for the popup form if you run a business internationally and want to launch a local campaign for a specific country.
You can set specific display rules for your audience. The frequency depends on your campaign goals. For most campaigns, we recommend setting a cap of “once per session” or “once per day”. If you run a welcome offer, it’s better not to show it more than once. Show reminders more often, like every 30 minutes. If you run seasonal sales, consider showing your popup form every 2-3 days.
Clapo offers the following frequency capping options:
If you think that a user might want to return to your offer later after closing it, you can use the Teaser feature. It’s a small widget that rests on the side of the screen and allows users to reopen the main popup form.
Yes, you can trigger Claspo popup forms when your visitors click a specific button, link, or banner. To set it up, go to Triggering settings, enable HTML element click-based toggle, copy the CSS selector of the required element, and paste it into the field.
Claspo allows you to launch popup forms on specific pages. To show a popup form only on the homepage, go to Triggering rules → Rule-based toggle → On pages option → URL (Equals). Add the correct URL (including https:// and trailing slashes), and you’re good to go. Alternatively, you can exclude pages on which you don’t want to show your popup form.
Yes, it’s possible. The main trick is not to ask for all the information at once. Our studies show that asking for a phone number and email address at the same time on a simple popup form can drop CR to 1%.
If you need to collect info like phone number, birthday, and preferences, use a multi-step form.
It’s a good practice to collect preferences with checkboxes or dropdowns, because it eases the cognitive load for users and they are more likely to finish filling out the form.
Yes, with Claspo integrations, you can manage how new leads will be organized in your ESP. In the settings, you can select destination lists, like Newsletter or Black Friday. For supported integrations, you can add tags to label new subscribers automatically. Besides, you can use Static fields to pass extra data from your popup form to any CRM or ESP.
Yes, this is a default behaviour in Claspo popup forms. First, every data field can be marked as required, so that users don’t skip them. Second, Claspo runs automatic validation in the background and shows the error message if the format is invalid. This eliminates typos and fake leads.
I installed Claspo to get an email newsletter popup when customers are getting ready to leave the page and it looks great! I also noticed that there are so many other popup options! It seems like it has the features of multiple apps all rolled into one. I'm looking forward to experimenting with all the options.
Smooth setup and integration with Shopify. App immediately recognized my store and connected without extra steps. The templates are modern and seasonal options are a big plus. Customization is quick and user-friendly, and I was able to sync email signups directly into Klaviyo with no issues.
Marketing Manager
For us, it actually works and stops people from leaving. The targeting settings let us show the pop-up only to potential clients who are really interested in our services. We synced Claspo with our CRM, and it helps us filter for the serious leads. Customer support was nice and helpful when we had questions.
Claspo’s gamification features are superb — truly a standout compared to other popup and form tools. The interactive elements with smooth animations make it fun and engaging for users, and it’s noticeably boosted our email capture rate by 2X within just a month. It’s also a powerful, no-code all-in-one widget platform — deploying popups, forms, and banners is fast and intuitive, with a large template library and strong personalization options.
Marketing Director
We had some high-traffic pages but they didn't convert. Most visitors didn’t notice our contact form, so they stayed for a while and then left, and we were losing potential clients. We added Claspo exit-intent popups offering a free consultation or audit. Next, we connected the popups to HubSpot in order to sync emails with the sales team. We also ran A/B tests on different messages to see what would be best for our audience. In a month, consultation requests went up by 19%, and we learned which services people were most interested in.
