Claspo Popup Builders

<p>Claspo popup plugin — gamified opt-in flows for high-intent email & SMS subscribers</p>
<p>Capture high-intent subscribers and drive more sales</p>
<p>Most popup plugins help you collect emails. Claspo helps you build buyers before they ever reach your ESP. Instead of chasing raw signup numbers, it helps you:</p>
<ul>
<li>capture visitors with genuine purchase intent;</li>
<li>qualify and warm them up before they subscribe;</li>
<li>avoid unnecessary discounting;</li>
<li>measure real revenue impact.</li>
</ul>
<p>Your ESP manages subscribers. Claspo influences buying decisions before they become one.</p>

<h3>Triple your conversions with gamified popups</h3>
<p>Based on our <a href="https://claspo.io/blog/popup-statistics/" rel="nofollow ugc">benchmarks</a> — built on the analysis of thousands of live widgets across different industries — gamified popups generate, on average, 3× higher opt-in conversion rates compared to standard popups. And that’s not the ceiling. Well-designed campaigns can perform significantly above that benchmark.</p>
<blockquote>
<p>“We saw a huge improvement in sign-up rates — going from around 3–5% to as high as 50% with the gamified widgets.”<br />
  — Borys Skowron, Founder of WHOSE</p>

<p>Gamification works because it creates anticipation, commitment, and stronger buying intent.</p>
<p>You stay in control:</p>
<ul>
<li>define reward distribution;</li>
<li>set probability of outcomes;</li>
<li>choose incentive types (discounts, free shipping, gifts, etc.).</li>
</ul>
<span class="embed-youtube" style="text-align:center; display: block;"><iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/Ti4weWZ660I?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe></span>
<h3>Understand intent before the opt-in</h3>
<p>Collecting an email is easy. Understanding who you’re adding to your list is more valuable.</p>
<p>Claspo lets you guide visitors through small qualification steps before asking for email. You can identify:</p>
<ul>
<li>what they’re interested in;</li>
<li>how ready they are to buy;</li>
<li>which incentives resonate most.</li>
</ul>
<p>This makes your follow-ups more relevant and increases conversions.</p>
<h3>Convert more visitors across every stage of the journey</h3>
<p>Claspo enables layered campaigns based on real user context:</p>
<ul>
<li>pages, categories, or products;</li>
<li>cart value and state;</li>
<li>traffic source and UTM parameters;</li>
<li>new vs returning visitors;</li>
<li>behavior (time on page, scroll depth, exit intent);</li>
<li>device type;</li>
<li>geolocation.</li>
</ul>
<p>This allows you to show offers only when they make sense — improving signup quality and reducing unnecessary discounts.</p>

<h3>Revenue-focused A/B testing on autopilot</h3>
<p>Claspo allows you to test entire campaign strategies, not just visuals.</p>
<p>Compare:</p>
<ul>
<li>audience segments;</li>
<li>incentive types;</li>
<li>triggers;</li>
<li>layouts;</li>
<li>messaging.</li>
</ul>
<p>Variants rotate automatically, and the best-performing version continues running — so optimization happens continuously without manual work.</p>
<h3>Launch conversion-ready campaigns fast</h3>
<p>Claspo helps you launch campaigns that feel native to your site:</p>
<ul>
<li>1,000+ CRO-focused templates (welcome flows, cart recovery, gamification);</li>
<li>automatic brand styling;</li>
<li>mobile-optimized layouts;</li>
<li>localization support (including RTL);</li>
<li>accessibility-friendly designs.</li>
</ul>
<p>Customize with drag-and-drop editor and go live in minutes.</p>
