Themify Popup – Responsive Popup Builder for WordPress

Themify Popup is a free, lightweight WordPress plugin that enables you to create fully responsive popups, such as newsletter forms, promotion banners, and content lightboxes. It offers powerful triggers (exit intent, timed delay, scroll position, page views), scheduling, animation options, and precise visitor targeting—integrating seamlessly with the Themify Builder for designing popup layouts via live drag-and-drop preview.

Key Features:

• Multiple Trigger Types: Support for exit intent, time‑delay, scroll position, page views, and manual launch buttons
• Flexible Popup Styles: Choose from Classic Center, Slide-Out (from any edge), Fullscreen, Auto-Close, and WordPress content popups.
• Targeting & Scheduling Options: Display popups on all pages or specific posts/pages/categories, to guests or specific user roles, within specific date/time windows.
• Animation & Display Control: Includes over 40 entrance/exit animations, auto-close timers, mobile disable option, and “show once per visitor” cookies.
• Themify Builder Integration: Design popups visually using Themify Builder (or Builder Lite), with frontend live editing. 
• Manual Launch Button Shortcode: Insert a button (e.g. “View Offer”) that triggers a popup manually. 
• Popup Dimension & Overlay Control: Set custom width/height, auto height options, overlay color, and whether overlay itself can close the popup.
• Lightweight & Performance Friendly: Minimal JavaScript footprint—lighter than many premium popup plugins—with no extra bloat.
• Highly Rated & Secure: Rated 4.9/5 with over 9K active installations.
