Substack Importer

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.
