I would like to add a signup form in the middle of my blog/newsletter posts. Is it possible yet? Because it would drastically increase the signup rate (It is possible on substack for example)
Can you do this by pasting HTML into the post itself.
I wrote about this a month or so ago: https://cove.chat/blog/how-to-add-an-email-subscribe-form-within-a-post-in-ghost/
You could use the example HTML code there or copy the HTML code from your current theme’s subscribe form.
