How do I import my posts from another platform, such as Mailchimp, WordPress, Medium, or Ghost?

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

How do import my posts manually?

If you're running into issues with exporting a file or importing it to your Substack publication, you can copy-and-paste each post into the Substack editor.

Once each post has been published, you can go into that post’s settings and change the publication date so that it matches the date of original publication.
