Substack Importer Plugin

The Substack Importer will import content from an export file downloaded from your Substack newsletter.

The following content will be imported:

• Posts and images.
• Podcasts.
• Comments (only for publicly accessible posts).
• Author information.

In the future, we plan to improve the importer by:

• Mailing lists.
• Enhancing the performance of processing export files with many posts and media.

This plugin depends on the WordPress Importer plugin which needs to be installed first.

To install the Substack Importer:

1. Upload the substack-importer directory to the /wp-content/plugins/ directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress
