Everything Your Popup Needs to Grow the List

Built in your free dashboard, shown on your site with one line of code.

Show It at the Right Moment

Pick the trigger and the audience, so the popup reaches people when they are ready, not the second they land.

  • Exit intent, a delay, a scroll, inactivity, a page count or a click
  • Target pages, devices, new or returning visitors and countries
  • Show it again after a week, or once per visit

The Code Appears After Signup

Your discount stays hidden until the visitor leaves an email. Then it shows with a copy button.

  • Nobody can copy it from the page source
  • On Shopify it applies itself at checkout

Frequently Asked Questions

What is a popup generator?

A tool that builds the popup for you, with no code: pick a template, change the words and colors, and paste one line on your site. ProveSource Boost does it in a free dashboard and keeps every lead for you.

Popup or inline form: which should I use?

A popup gets seen, because it asks for attention at a set moment. An inline form sits in the page and never interrupts. Many sites run both: an exit-intent popup on product pages and an inline form under blog posts.

Where do my leads go?

Every signup is saved in your dashboard, ready to export as CSV. Send each one to Zapier, Make, Klaviyo, Mailchimp, HubSpot or Google Sheets through a webhook, and get an email alert the moment it arrives.

Can it show on exit intent?

Yes. Show it when a visitor is about to leave, after a delay, on scroll, after inactivity, on the Nth page, or on a click. Target specific pages, devices, new or returning visitors, and countries.

Can I give a discount code after signup?

Yes. Add a code and it appears after the visitor signs up, with a copy button. On Shopify it can apply itself at checkout.

Is there a free WordPress popup plugin?

Yes. ProveSource Boost is on wordpress.org. Install it, connect your free account, and your popups show on every page with no code to paste. Signup forms inside a page go wherever you place the Boost block.

Are popups bad for SEO?

Not when they wait their turn. Google warns against popups that cover the main content on mobile as soon as someone lands from search. Show yours after a delay or a scroll, on exit intent, or as a corner card.

Can I put the signup form inside the page instead?

Yes. The inline layout draws the same form inside your content with no overlay, so it fits under a blog post or in a sidebar.

Is it really free?

Yes. The free plan includes 3 widgets and 1,000 views a month with every feature and unlimited leads, and shows a small ProveSource badge. Pro is $24 a month or $195 a year for unlimited widgets and views, with no badge.

Do I need a developer?

No. You paste one line of code, the same on every platform. Your dashboard has step-by-step instructions for Shopify, WordPress, Wix, Squarespace, Webflow, Framer and Google Tag Manager.

Will it slow down my site?

No. The script loads asynchronously from a CDN after your page renders. Widgets draw in an isolated layer, so your theme's CSS can't break them and theirs can't touch your site.

Can I edit it after it's live?

Yes. The tag only carries your widget ID. Save a change in your free dashboard and your site shows it on the next page view. You never touch the code again.

Your Next Subscriber Is on the Page Right Now

Pick a template, write your offer and paste one line. Your popup is live in about 2 minutes.
