Boxzilla

Boxzilla is a versatile plugin designed for WordPress sites.

It allows users to add popup or slidein boxes to their site, which can contain any content and can slide or fade in at any point.

This plugin is ideal for calltoaction prompts, newsletters, and social media integration.

While the core Boxzilla plugin is free, there are several paid addons available that extend its functionality and support its ongoing development.

These addons can be browsed and purchased separately.
