Podpage makes it easy to collect email address directly to ConvertKit right from your website. You can add an inline form or a modal to your website.
Go to Settings → Collect Emails in your Podpage Dashboard.
Create an inline form
An inline form will show on the sidebar of your home page and episode pages.
First, go create an "Inline" form at https://app.convertkit.com/forms/. We recommend using the Clare or Mills template.
Copy the embed code and add that to the Podpage dashboard and hit submit.
