Start on a staging site
Download the Free beta ZIP. In WordPress, open Plugins → Add New → Upload Plugin. Choose the ZIP, install and activate it. Open Newsletter Platform from the WordPress menu. This early-access release is for staging evaluation; keep a backup before testing.
Check the essentials
The declared minimums are WordPress 6.5 and PHP 8.0. The beta4 isolated runtime checks used WordPress 7.1.2, PHP 8.4.26 and WooCommerce 11.1.2; broader version and email-client coverage is still in progress. Network-wide multisite activation is not supported.
Make it yours
Use the top navigation to move between your workspace, campaigns, audience, forms and settings. Set your sender details, choose a Free design and save a draft. Free does not need a Newsletter Platform account.
Adding Pro
Follow the five-step guide in the workspace: save sender details, choose a Free design, send yourself an owned-address test, review the audience, then explicitly confirm a schedule. Progress follows the saved draft. Free needs no vendor account.
