Google Annotations - on some emails with drag-and-drop editor?

Hi ​@MMacca,

Interesting that Google Annotations appeared for a couple of the emails you sent to your Gmail. You mentioned that you built this email using the drag-and-drop editor, but at any point, did you or anyone on your team edit the source code of a text block or add an HTML block that allowed Google to see annotations? This article, by Google, explains how to add code to your emails that add annotations, and can technically be done in text/HTML blocks in the drag and drop editor. 

Additionally, were these templates you used uploaded to Klaviyo from your device, or a 3rd party?

Thanks for the reply ​@Byrne C! I’m the only one who edits and I only do it via drag-and-drop - never been brave enough to try html block stuff! And it’s just me working on Klaviyo, no third parties. It’s a real mystery as to why a few emails have shown with Google Annotations!
