Description
Addons Manager centralizes the installation, activation, and updating of all Newsletter extensions within a single screen in the WordPress dashboard, eliminating the need to download ZIP files and perform manual uploads via FTP. The addon lists the official catalog of available add-ons, identifies which are already active on the site, and flags when new versions are ready to be applied.
