To embed a signup form for your Substack publication, head to your publication's Settings page and click Import in the left navigation bar. In this section, you'll see a unique code for your publication (see below for an example).
You can insert the HTML code onto any website to embed a signup form for your Substack publication.
Note: Our embed signup forms work on any platform that supports iFrames (WordPress, Squarespace, custom websites, etc.) but this excludes Medium.
At this time, the embed signup form is not customizable.
If you'd like to hide your publication name and logo from the signup form, slide the toggle to the right next to "Hide your pub logo and name on the sign up form". Copy the new code that appears and paste it into your website.
The form will appear without your Substack publication's name and logo and just a space for new readers to enter their email addresses. After clicking "Subscribe", readers will then see the subscription plan options if you have payments enabled or the pledges options if you have Pledges enabled. If you're recommending other publications on Substack, your new subscriber can easily subscribe to these publications in one spot.
