I am also encountering double featured images in my MailChimp email outbound campaigns. I only want 1x featured image (not two!).
Example: https://us19.campaign-archive.com/?u=37fc762c85d0cc8b8f5981860&id=885639fd92
My RSS Feed URL: https://www.fantasybasketball101.com/feed/
I contacted MailChimp and they informed me it’s likely my RSS feed and nothing to do with Mail Chimp.
Do you know how to fix it?
Please let me know.
Thank you.
