while this option currently isn’t available in the drag & drop editor, you could use this workaround that @alyssamwilie & @MatthewShepherd shared in this Community thread.
I understand your use case here and how it would be beneficial to have a quick social share option for the email marketing content in the drag&drop editor, that’s why I wanted to share these two Ideas Forum requests that other users have created:
We use the Ideas forum to collect ideas on how we can improve the product for our customers. Product pays particular attention to the top voted ideas & takes them into consideration along with other feedback channels as well as their own vision to understand what features will be most valuable. It would be great if you upvote the ideas and share your feedback in the comments. Thank you!
I hope this helps,
Mia, Community Team
