There’s an admin page where you can manage the slug and preview (which correspond to the link url and meta description). E.g., if your email subject is “hello world”, your url will be “/hello-world-a1b2c3d.html” and the default preview/meta description will be the first 200 characters of your email. Now, the admin page lets you edit the subject and the preview. So if you change the subject to “Goodbye World”, your url will change to “goodbye-world—a1b2c3d.html”. Notice how a1b2c3d stays unchanged? That’s the string used to identify the email internally. I haven’t exactly implemented post editing but I have a Medium style post editor built into my inbox. Next step will be to surface the email in the inbox and reply to myself with the correct content. Also, sorry for the late reply. I didn’t realize someone had replied to the original comment. Hope it helps.
