Install

No release zip yet. The repository archive installs, but the folder name will carry the branch suffix and updates will not flow:

wp plugin install https://github.com/ultimate-multisite/omni-platform-newsletter/archive/refs/heads/main.zip
Readme github.com/ultimate-multisite/omni-platform-newsletter ↗

Write a newsletter once in the WordPress block editor and publish it as:

  • a responsive webpage;
  • responsive, email-safe HTML through Newspack Newsletters; and
  • a two-sided US Letter print/PDF layout through Print My Blog Pro Print.

The plugin is intended for nonprofits and other organizations that need one reviewed source of truth for web, email, and physical mail. It does not import contacts, configure a sending provider, or send campaigns.

Requirements

Authoring contract

Insert the Omni duplex newsletter block pattern into a Newspack newsletter. It creates exactly four top-level groups:

  • opn-source-sidebar
  • opn-source-front
  • opn-source-back
  • opn-source-footer

Sidebar and footer content are stored once. They repeat on both print sides; email output places the stories first and contact/support information once at the end. Unexpected or duplicate top-level content falls back visibly rather than being silently discarded.

The default print palette uses slate, navy, yellow, and white. Themes can override the --opn-* custom properties under .opn-issue without changing the plugin. The fixed two-page layout has a deliberate content budget; excess copy is flagged and is never hidden or automatically shrunk.

Development

composer install
composer test

composer test validates PHP syntax, PSR-12 style, the JavaScript asset, and the section/fallback contract.

Status

Version 0.1 provides the proven Newspack + Print My Blog adapter. Additional authoring, email, and print adapters can be introduced without changing the four-section content contract.
