A ConvertKit integration with Webflow CMS would be amazing — similar to the integration that already exists for WordPress (https://updates.convertkit.com/item/15100). In a nutshell, this integration would not be forms for collecting emails (as it was already mentioned that this exists), but it's publishing posts (as CMS items in Webflow), as broadcasts (emails) are sent out from ConvertKit.
This would save SO much time for people like me who send out weekly email newsletters using ConvertKit and have to manually add them into Webflow CMS so they're on our website, blog-style. Pasting, editing text, and re-uploading pictures is such a pain!
