What a copy needs to do

  • One popup with an email field
  • Shows after a set delay or on exit intent
  • Once per visitor every 7 days
  • Saves each email to a Google Sheet
  • A snippet to paste into any site

How to build it yourself

  1. One script tag on the buyer's site adds the popup as an HTML dialog element.3
  2. The setTimeout method runs the code that opens the popup once its timer expires.4
  3. Exit intent listens for the mouseout event as the cursor leaves the page.5
  4. A timestamp in localStorage, which has no expiration, limits how often a visitor sees the popup.6
  5. The form posts each email to a Next.js endpoint, and CORS headers allow the cross-origin request.7
  6. The buyer connects Google Sheets through their own Composio account with OAuth.8
  7. Composio's Google Sheets toolkit includes a tool that appends each email as a new row.8

What a copy leaves out

  • Targeting by CRM data and referring site
  • Multi-step funnels and scored surveys
  • Video messages and deadline redirects
  • ConvertBox's name, look and templates
