Substack enables seamless content imports from the following services: Medium, Ghost, Wordpress, Mailchimp, Beehiiv, SeekingAlpha, Tumblr, and Blogspot. Just paste in your blog or newsletter URL to get started.

If you use a different platform from the ones listed, check if they have an RSS feed. Our post importer also takes in RSS feeds from sites like Squarespace and ConvertKit.

Things to note:

1. Some platforms will only include the most recent posts, such as the latest 20 posts, in their RSS.

2. Here are detailed guides on moving from Ghost to Substack or Mailchimp to Substack or Beehiv to Substack.

1. Log into your account and navigate to your publication's Settings page. Click on Import/Export in the left navigation bar. 

2. Click on "Import posts".

3. Paste the URL of the website you'd like to import, such as https://tinyletter.com/your or https://medium.com/@your. If you're importing your posts from Mailchimp, use your email campaign archive as the URL.

Tip: If you're importing content from Seeking Alpha, use the following URL: http://seekingalpha.com/author/<author_id>. Replace "author_id" with your Seeking Alpha author name. For example: http://seekingalpha.com/author/hamish-best

4. Once the Substack importer has found your archive, select "Import". Alternatively, you can upload a .csv file of your posts. If you have payments enabled on your Substack publication, you'll see the option to import the posts as paid posts.
