How to Install the Bulk Messenger Plugin

Here’s my first published plugin! This bulk-messenger plugin helps you send bulk messages via the Message app (Apple-only) that are formatted with personalized variables.

There are two ways to install the plugin: 1) using Claude Desktop, or 2) using Claude Code via the terminal. You will need to add my Marketplace before installing the plugin.

Using Claude Desktop

  1. Open your Claude Code Desktop
  2. Select “Plugins” from the sidebar menu
  3. Select “+” then select “Add Marketplace from GitHub
