Submitting on behalf of the client for account ID 815 - M2 Paleo Plan.
The client is looking to use Annotations in the content so that they would be visible in the Gmail Promotions tab.
The client mentioned that they sent a campaign once from Maropost and it showed images in the inbox similar to how the annotations appear, however, when we tested the same content they were not visible.

The client requested for this feature to be provided for the contents as using annotations would be beneficial for them.
