Use SW CTA Popup for one simple popup with a quick setup. Use SW Popup Panel for multiple variants, page-specific rules, more positions, announcement banners, and finer triggers.
SW CTA Popup is the quicker option when you need one simple popup, usually in a bottom corner, with one main variant. It can work for a single offer or a straightforward site-wide promotion.
SW Popup Panel is the more flexible option. Use it when you need multiple variants, different content on different pages, announcement-style panels, more positions, or more detailed trigger behavior.
