Substack Importer

68 Quality Score

Active Installs

14/30

With only 1,000 active installs, adoption is modest and reflects the narrow audience of writers leaving Substack rather than broad WordPress demand.

Update Freshness

25/25

The plugin was last updated on April 22, 2026, showing a recently maintained codebase that keeps pace with WordPress core releases.

User Rating

7/15

A rating of 56 out of 100 from only 4 reviewers is too small a sample to draw firm conclusions, and the score is mediocre even within that limited set.

Support Health

8/15

With zero support threads and a zero percent resolution rate, there is essentially no track record of the developer responding to user issues in the public forums.

WP Compatibility

15/15

The plugin is tested against WordPress 6.9.4, requires only WordPress 5.2 and PHP 7.4, so it will run cleanly on essentially any modern WordPress install.

What It Does

The Substack Importer imports posts from a Substack newsletter into a WordPress site, letting writers move away from Substack's hosted platform. It handles the core migration task of pulling content into the WordPress editor so posts become regular WP entries rather than living exclusively on Substack.

Who It's For

This plugin fits independent writers, journalists, and content creators who have built an audience on Substack and want to consolidate their archive on a self-hosted WordPress site they fully control. It also suits consultants and founders who want to repurpose newsletter content into a broader knowledge base or personal brand website.

Who Should Skip It

If you have not yet built a substantial archive on Substack, or if you prefer Substack's built-in audience, payment, and email delivery features, there is no reason to migrate. Sites that need ongoing sync between Substack and WordPress should also look elsewhere, as this appears to be a one-time import tool.

The Bottom Line

Substack Importer does a specific job and does it on a recently maintained codebase with broad WordPress compatibility, earning an overall score of 67.65 out of 100. The thin user base, tiny rating sample, and absent support history mean you should test the import on a staging site before committing, and accept that help may be slow if something breaks. For most Substack writers who simply want their posts in WordPress, it is a reasonable option with the caveat that you are trusting a small project.
