Building Custom Emails from Notion Data: Need Code Suggestions

Hey everyone! I’m trying to build a custom flow that pulls data from Notion and sends styled emails to new vendor suppliers. I’ve got the HTML with inline CSS ready, but I couldn’t find any working code/action element to plug it into. Tools like Stripo or MailChimp won’t work for this case, so I need a way to generate the styled email output using my own snippet. Any ideas? cc Marvin A.
